Coming of Age in a Low-Density Universe

Posted in Biographical, Open Access, The Universe and Stuff with tags , , , , on August 25, 2024 by telescoper

I was reminded just now that 30 years ago today, on 25th August 1994, this review article by myself and George Ellis was published in Nature (volume 370, pp. 609–615).

Sorry for the somewhat scrappy scanned copy. The article is still behind a paywall. No open access for the open Universe!

Can this really have been 30 years ago?

Anyway, that was the day I officially became labelled a “crank”, by some, although others thought we were pushing at an open door. We were arguing against the then-standard cosmological model (based on the Einstein – de Sitter model), but the weight of evidence was already starting to shift. Although we didn’t predict the arrival of dark energy, the arguments we presented about the density of matter did turn out to be correct. A lot has changed since 1994, but we continue to live in a Universe with a density of matter much lower than the critical density and our best estimate of what that density is was spot on.

Looking back on this, I think valuable lessons would be learned if someone had the time and energy to go through precisely why so many papers at that time were consistent with a higher-density Universe that we have now settled on. Confirmation bias undoubtedly played a role, and who is to say that it isn’t relevant to this day?

New Publication at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , on August 24, 2024 by telescoper

It’s Saturday morning so it’s time for the usual weekly update of publications at the Open Journal of Astrophysics. Once again this week’s report will be short because there is only one paper to report this week, being  the 69th paper in Volume 7 (2024)  and the 184th  altogether. It was published on Wednesday 21st August 2024.

This week has been a bit strange, actually. We have actually accepted four papers that I was expecting to publish this week but only one has been published because the authors of the others have not yet put the final versions on arXiv. I suppose this is due to ongoing holidays and they’ll appear in due course. The other thing that happened was that when I published the paper below I discovered that the Crossref system was down for a scheduled upgrade that took a whole day to complete. Although I published the paper on 21st August I couldn’t register the metadata, etc, until 22nd August. Just as well I didn’t have more to do really!

Anyway, the title of the latest paper is is The compact circumstellar material of SN 2024ggi: another supernova with a pre-explosion effervescent zone and jet-driven explosion and it  is in the folder marked High-Energy Astrophysical Phenomena. The author is Noam Soker of Technion, Haifa, in Israel; the paper presents a possible explanation of then properties of recently-observed supernova SN 2024ggi.

Here is the overlay of the paper containing the abstract:

Three New Publications at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , , , , , , on August 10, 2024 by telescoper

It’s Saturday so it’s time once again for another roundup of business at the  Open Journal of Astrophysics. After last week’s summer lull, this week I have three papers to announce, which brings the total we have published so far this year (Vol. 7) to 67 and the total published by OJAp to 182.

First one up, published on 7th August 2024, is “Brightest Cluster Galaxy Offsets in Cold Dark Matter” by Jonathan Katz of Washington University (St Louis, Missouri, USA),  a simulation-based study of the distribution of the position of brightest cluster galaxies relative to the dark matter distribution and its possible use as a cosmological probe.  The authors are Cian Roche (MIT), Michael McDonald (MIT), Josh Borrow (MIT), Mark Vogelsberger (MIT), Xuejian Shen (MIT), Volker Springel (MPA Garching), Lars Hernquist (Harvard), Ruediger Pakmor (Harvard), Sownak Bose (Durham, UK) and Rahul Kannan (York U., Canada). This paper is in the folder marked Astrophysics of Galaxies.

Here is a screen grab of the overlay, which includes the abstract:

 

 

You can read the paper directly on arXiv here.

The second paper to present is “LAMOST J1010+2358 is not a Pair-Instability Supernova Relic” by five authors based in the USA: Pierre Thibodeaux (Chicago), Alexander P. Ji (Chicago), William Cerny (Yale), Evan N. Kirby (Notre Dame) and Joshua D. Simon (Carnegie Observatories) .  As the title makes clear, the paper presents arguments against previous claims that a particular star is not a pair-instability supernova relic. This paper is in the folder marked Solar and Stellar Astrophysics. It was published on Friday August 9th 2024.

The overlay looks like this:

 

 

 

You can read this paper directly on the arXiv here.

Last, but by no means least, comes  “A Pilot Search for Gravitational Self-Lensing Binaries with the Zwicky Transient Facility“, results of a trial search for signals of gravitational lensing of one component in a binary system by a compact companion, with a discussion of future prospects for larger surveys. This one, which was also published on 9th August, is in the folder marked High-Energy Astrophysical Phenomena. The authors are Allison Crossland & Eric C Bellm (U. Washington), Courtney Klein (UC Irvine), James R. A. Davenport (U. Washington), Thomas Kupfer (Hamburg Observatory) and Steven L. Groom, Russ R. Laher & Reed Riddle (Caltech).

That’s it for this week. I hope to post another update next weekend.

Open Access Encounters: The Good, The Bad and the Ugly

Posted in Open Access with tags , , , on August 7, 2024 by telescoper

As it was foretold on Saturday, this afternoon I gave a talk at the 32nd General Assembly of the International Astronomical Union currently taking place in Cape Town, or rather at a side event thereof called Open Access Encounters: The Good, The Bad and the Ugly. I actually gave the last talk in the session, which may or may not mean that I was representing The Ugly…

About 50 people attended online plus an unknown number in person, so it was quite a decent size of audiance.

I’m not sure if Slideshare is still working on WordPress, but if not here is a PDF of the slides.

Open Access Updates & Announcements

Posted in Open Access with tags , , , on August 3, 2024 by telescoper

When I wrote last week’s update on papers published at the Open Journal of Astrophysics, I was a little surprised that our publishing activity had not tailed off because of the summer vacations. Well, it has now because we haven’t publish any papers this week! Rather than not post an update at all, however, I thought I’d point out a few interesting things that have happened in the world of open access.

First. I draw your attention to an article in C&EN (Chemical & Engineering News) reflecting on the fact that the Gates Foundation (one of the largest research charities in the world) announced in March 2024 that, starting from Jan. 1, 2025, it would no longer cover publishing costs. I actually wrote about this decision here. The article is largely about the threat this poses to the Gold Open Access model, which in my opinion thoroughly deserves to be threatened. It does, however, talk briefly about Diamond Open Access which commercial publishers don’t like as it removes – or should do – their source of profits:

Another alternative model is diamond OA, in which all research papers and their associated peer-reviewed reports are published without fees for the author or the reader and are also freely available to read and reuse. 

It goes on to say:

Under diamond OA, publishers are no longer gatekeepers of research. Instead, they become service providers that handle manuscript submissions, typesetting, and copyediting. This is in contrast to the current publishing system, in which the publisher controls everything from the copyright to the production process.

I don’t really agree with even the limited role of “service providers” mentioned here, as much of what that role entails just involves a decent reviewing platform. Elsewhere the article says that moving to Diamond OA would entail a significant cost. That may be but, as I’ve said over and over again, the actual cost of online publishing is low compared to the level of profit extracted by commercial publishers. The cost to academia of moving to Diamond OA would be much less than not moving to Diamond OA.

The second item I’d like to draw your attention is called Choosing a publisher? It’s not all about the impact factor and is by Antigoni Messaritaki, a senior publisher at IOP Publishing,  When I saw the title I thought that it might be about the uselessness of Journal Impact Factors and a commitment by IOP Publishing to stop using them. Sadly it’s nothing of the sort. It tries to entice authors to look beyond journal impact factors when choosing a publisher, pushing Open Access as an important factor to consider. It admits that APCs are expensive, but never even mentions Diamond OA. It’s an entirely self-serving piece. I find the IOP’s stance on publishing, and the disingenuous way they try to excuse their own profiteering, unethical and unacceptable. That’s why I resigned my fellowship of the IOP.

Last, and by all means least, I should draw your attention that the 32nd General Assembly of the International Astronomical Union takes place next week in Cape Town. I’m not attending in person – I’ve done enough travelling this year! – but I have accepted an invitation to give a remote talk at a side event called Open Access Encounters on Wednesday 7th August:

Taighde Éireann

Posted in Maynooth, Open Access, Science Politics with tags , , , , , , , , , , on July 31, 2024 by telescoper

On 1st August 2024, i.e. tomorrow, a new funding organization comes into existence in Ireland, formed by the merger of SFI with the Irish Research Council. The new outfit is called Taighde Éireann – Research Ireland and many of us working in Irish academia were optimistic that it might improve the funding environment in Ireland, especially with regard to basic research.

Taighde Éireann has not got off to a very promising start. In particular, the long-running saga of who would be Chief Executive Officer of the new organization does not inspire confidence. Professor Philip Nolan, former Director-General of Science Foundation Ireland was originally intended to take the helm, but then he was dismissed from his position at SFI which made the prospect of him taking over the new organization seem less likely. Indeed, more recently, it was announced that a new temporary CEO would be appointed “pending the recruitment of a new CEO on a permanent basis”.

Starting with a caretaker manager is far from ideal, although it probably just means that the interim CEO will just look after transferring activity from IRC and SFI to the new organization without actually changing much. I just hope that in the long run a person is appointed who actually understands research rather than a generic management type. Otherwise the only change that will actually happen will be purely administrative rather than the systemic overhaul of attitudes and culture that Ireland really needs. As an outsider, one way of reading the controversy of the CEO the current SFI establishment resisting any possibility of change.

From my own perspective, the fundamental problem is that research funding for fundamental science in Ireland is so limited as to be virtually non-existent by a matter of policy at Science Foundation Ireland, which basically only funds applied research. This is a short-sighted and damaging policy that is causing, among other things, a significant exodus of talented young researchers to opportunities elsewhere (especially in the EU).

I know there will be many competing calls for changes in practice for the new Council but I thought I would add a few suggestions that will probably be ignored but which I’ll make anyway.

  1. A funding stream should be set up to enable scientific exploitation of Ireland’s current memberships of the European Southern Observatory (ESO), European Space Agency (ESA) and future membership of CERN. Ireland’s membership of ESO provides a cautionary tale. The Irish astronomical community was very happy about the decision to join ESO, but that decision was not accompanied by significant funding to exploit the telescopes. Few astronomers have therefore been able to benefit from ESO membership. While there are other benefits of course, the return to science has been extremely limited. The phrase “to spoil a ship for a ha’porth of tar” springs to mind. Even a few PDRA and PhD positions would provide an enormous boost.
  2. There should be far less emphasis on top-down funding ventures, such as the research “Centres”. These lock up a huge amount of money which makes it much more difficult to provide support to exciting curiosity-driven research, which is often where real innovation occurs. Let’s have much more responsive-modem grants, including areas of basic research currently excluded by SFI policy. This could be done by simply expanding the remit of the SFI Frontiers programme.
  3. The current IRC Laureate programme is inadequate. This currently has one call every four years. It should be annual, even if fewer positions are funded in each round, to allow it to be more responsive.
  4. Ban the use of any funds from the new organization being wasted on Gold Open Access, but invest in Diamond Open Access activities across all disciplines (i.e. Arts and Humanities as well as Science).
  5. Work with Government to provide a much more coherent system of funding research infrastructure, including if necessary requiring HEIs to commit a share of their surpluses to capital projects. In the UK, for example, capital projects funded by research councils usually require 50% institutional contribution.

That’s just five off the top of my head. I’m sure others will have suggestions. If so, please feel free to make suggestions through the comments box below.

Four New Publications at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , , , , , , , , , , on July 27, 2024 by telescoper

It’s Saturday morning, so once again it’s time for an update of activity at the Open Journal of Astrophysics. This week we have published another batch of four papers, the same number as last week, which takes the count in Volume 7 (2024) up to 64 and the total published altogether by OJAp up to 179.

Before announcing the week’s papers I’ll add three other updates you might find interesting:

  1.  When I looked at NASA/ADS this morning to help construct this post I saw that papers published in OJAp have now garnered over 2500 citations between them;
  2. We had a good response to our recent call for new members of the Editorial Board and have added four new members here;
  3. Last week we received a significant (unsolicited) cash donation from a higher education institution based in Europe to help with our work in Diamond Open Access. If any other organizations or individuals would like to do similar then please contact me!

Now, in chronological order, the four papers published this week, with their overlays, are as follows. You can click on the images of the overlays to make them larger should you wish to do so.

First one up is: “Widespread disruption of resonant chains during protoplanetary disk dispersal by Bradley M S Hansen (UCLA), Tze-Yeung Yu (UCLA) and Yasuhiro Hasegawa (JPL), all based in California, USA.  The paper presents a discussion of the effect of a dispersing protoplanetary disk on the evolution of low-mass planets around a Solar mass star.  It was published on 21st July 2024 and is in the folder marked Earth and Planetary Astrophysics.

Here is a screen grab of the overlay, which includes the abstract:

 

You can find the officially accepted version of the paper on the arXiv here.

The second paper to announce is “Using A One-Class SVM To Optimize Transit Detection” by Jakob Roche of the University of South Florida, also in the USA (but not in California). This articles discusses the advantages of One-Class Support Vector Machines (SVMs) over Convolutional Neural Networks (CNN) in the context of exoplanet detection. Its in the folder called Instrumentation and Methods for Astrophysics and was published on 25th July 2024.

You can see the overlay here:

 

 

 

The accepted version of this paper can be found on the arXiv here.

The next paper, also published on 25th July 2024, is in the folder marked High-Energy Astrophysical Phenomena. Its primary classification on arXiv is General Relativity and Quantum Cosmology (gr-qc), but it is cross-listed on astro-ph so we considered it for publication and had it refereed, with favourable results. It is entitled “What no one has seen before: gravitational waveforms from warp drive collapse” and is by Katy Clough (QMUL, UK), Tim Dietrich (Potsdam, Germany) and Sebastian Khan (Cardiff, UK).  Looking at the title of this paper you might be tempted to dismiss it on the grounds that warp drives are the stuff of science fiction (which they are), but this paper is really a rigorous technical study of the dynamical evolution and stability of spacetimes that violate the null energy condition, inspired by the idea of a warp drive.

Here is the overlay:

 

 

You can find the full text for this one on the arXiv here.

Last, published on 26th July 2024, we have a paper with the title “A study of gamma-ray emission from OJ 287 using Fermi-LAT from 2015-2023” by Vibhavasu Pasumarti and Shantanu Desai of the Indian Institute of Technology, Hyderabad, India. It is an investigation of the properties of gamma-ray emission from OJ287 (a BL Lac object) using the Fermi Large Area Telescope (LAT).  This one is also in the folder marked High-Energy Astrophysical Phenomena; here is the overlay

That’s all for this week. Stay tuned for another update next week.

Four New Publications at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , on July 20, 2024 by telescoper

This week we have published four papers at the Open Journal of Astrophysics, which I now present to you here. These four take the count in Volume 7 (2024) up to 60 and the total published altogether by OJAp up to 175. It is gratifying to see the range of high-quality papers published steadily increasing. We are getting several papers submitted every day now.

In chronological order, the four papers published this week, with their overlays, are as follows. You can click on the images of the overlays to make them larger should you wish to do so.

First one up is: “A population of neutron star candidates in wide orbits from Gaia astrometry” by Kareem El-Badry (Caltech, USA) and 12 others based across the world.  The paper presents  a spectroscopic study of neutron star candidates identified using GAIA astrometry to be in wide binary orbits around main sequence stars,  was published on 15th July 2024 and is in the folder marked Solar and Stellar Astrophysics. For more information about this one, see here.

Here is a screen grab of the overlay, which includes the abstract:

 

You can find the officially accepted version of the paper on the arXiv here.

The second paper to announce is “Systematic Effects in Galaxy-Galaxy Lensing with DESI” and was written by Johannes Ulf Lange (University of Michigan, Ann Arbor, USA) and 58 others, again distributed internationally.  This one reports a study of systematic effects (such as incompleteness and intrinsic alignment) on galaxy-galaxy lensing results from the Dark Energy Spectroscopic Instrument (DESI) survey. This one is in the folder called Cosmology and NonGalactic Astrophysics and was published on 16th July 2024.

You can see the overlay here:

 

The accepted version of this paper can be found on the arXiv here.

The next paper is also in the folder called Cosmology and NonGalactic Astrophysics.  It is entitled “Unleashing cosmic shear information with the tomographic weak lensing PDF” and is by by Lina Castiblanco (Newcastle Univresity, UK), Cora Uhlemann (Bielefeld University, Germany), Joachim Harnois-Déraps (Newcastle University, UK) and Alexandre Barthelemy (Ludwig-Maximilians-Universität, Germany). This one was published on 17th July 2024.

Here is the overlay:

 

You can find the full text for this one on the arXiv here.

Last but by no means least, published on 18th July 2024, we have a paper  entitled “When to interfere with dark matter? The impact of wave dynamics on statistics“. The primary classification for this one is again Cosmology and Nongalactic Astrophysics and it discusses the imprint of wave-mechanical behaviour, perhaps associated with ultra-light scalar field dark matter on the statistical properties of large-scale structure. The authors are Alex Gough (Newcastle University, UK) and Cora Uhlemann (Bielefeld University, Germany; who also featured in the author list of the previous paper). This is a paper close to my own interests, but because I know both authors well and was the PhD examiner of the first author I thought it best to recuse myself from an editorial role on this one.

 

You can click on the image of the overlay to make it larger should you wish to do so. You can find the officially accepted version of the paper on the arXiv here.

It did look likely at one stage that we might publish a paper every day last week, but the final version of one other paper didn’t make it onto arXiv in time to be announced on Friday so I will publish that one on Monday.

Academic Publishing is a Lucrative Scam

Posted in OJAp Papers, Open Access with tags , , , , , , , , on July 17, 2024 by telescoper

I saw an article in the Guardian yesterday with the title Academic journals are a lucrative scam – and we’re determined to change that. It’s written by Arash Abizadeh who is Professor of Political Science at McGill University in Canada. I urge you to read the piece if you’re interested in Open Access and the issues surrounding it.

I agree with virtually everything in the article. Indeed I’ve been saying much the same thing for about 15 years! I’m also determined to change things too, which is why we set up the Open Journal of Astrophysics, a “Diamond” Open Access Journal. Talking about the system of Gold Open Access, Prof. Abizadeh writes:

There is an obvious alternative: universities, libraries, and academic funding agencies can cut out the intermediary and directly fund journals themselves, at a far lower cost. This would remove commercial pressures from the editorial process, preserve editorial integrity and make research accessible to all. The term for this is “diamond” open access, which means the publishers charge neither authors, editors, nor readers (this is how our new journal will operate). Librarians have been urging this for years. So why haven’t academics already migrated to diamond journals?

I think the reason more academics haven’t already migrated to Diamond Open Access journals is that there are relatively few such journals. The reason for that is that although there are lots of people talking about Diamond Open Access there are many fewer actually taking steps to implement it. The initiative mentioned in the Guardian article is therefore very welcome. Although I think in the long run this transition is inevitable, it won’t happen by itself. It certainly won’t be helped by the Academic Publishing Industry either. We academics have to provide the push.

Here’s another excerpt:

Career advancement depends heavily on publishing in journals with established name recognition and prestige, and these journals are often owned by commercial publishers. Many academics – particularly early-career researchers trying to secure long-term employment in an extremely difficult job market – cannot afford to take a chance on new, untested journals on their own.

This is true, up to a point.

First of all any institution that has signed up to the San Francisco Declaration On Research Assessment (DORA) should not be relying on (often bogus) indicators of prestige such as the Journal Impact Factor or the journal’s presence in the Scopus index. If Diamond Open Access is to gain further traction it has to be accompanied to a wholesale change towards fairer research assessment practices.

Second, although it is true that it has taken some years to reach the volume it has now, I have been pleasantly surprised how many early career researchers in astrophysics have been keen to try out the Open Journal of Astrophysics. I think that’s because (a) early career researchers have not been indoctrinated into the absurdities of existing publishing practices and (b) they can see that the citation rates on OJAp are no worse than other allegedly more “prestigious” journals.
