Western Sydney

Posted in Biographical, Open Access with tags , , , , , , on February 26, 2024 by telescoper

Today I made a journey by train to Kingswood, a suburb of Sydney which is the location of one of the campuses of Western Sydney University (WSU). The journey of about 50 km takes about an hour on the stopping train (T1) from Sydney Central Station. I was intrigued that the final destination for the train I got was Emu Plains; I had visions of vast herds of Emus gathered there, but I had to get off the stop before the terminus so never saw them. There’s about a 20-minute walk to the campus from Kingswood Station. It was quite warm so I was grateful when one of my hosts offered me a lift back to Kingswood Station at the end of my visit.

The reason for my visit was set another seminar about Open Access Publishing in Astrophysics. Here are the slides:

Although I’ve given a talk based on more-or-less the same slides recently, it always comes out slightly different. There was a bigger audience than I expected in the room, supplemented by even more on Zoom. The topic of Open Access Publishing does seem to be pretty hot these days in Australia and there was quite a lively discussion. I have a feeling we might have a manuscript or two submitted from WSU before too long.

Kingswood is a far less affluent area than where I am staying in Ultimo, and WSU is an institution that’s very different from the University of Sydney itself, but it was good to see another side of the city, geographically as well as socially. Thank you to everyone who attended and, especially, to Luke Barnes for inviting me and for lunch and coffee!

On the train back into Sydney I noticed that trains going in the opposite direction where crammed full, with (mostly) teenage girls heading to Olympic Park for a Taylor Swift concert. My train, heading into Sydney was fairly empty by contrast and the journey back pleasant enough.

Two New Publications at the Open Journal of Astrophysics

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

It’s Saturday morning in Sydney, and time to post another update relating to the  Open Journal of Astrophysics.  Since the last update we have published two more papers, taking  the count in Volume 7 (2024) up to 15 and the total published by OJAp up to 130. I should have posted these before leaving but it slipped my mind.

The first paper of the most recent pair – published on  Thursday 22nd February – is “Modelling cross-correlations of ultra-high-energy cosmic rays and galaxies” by Federico Urban (Prague, Czech Republic), Stefano Camera (Torino, Italy) and David Alonso (Oxford, UK). It presents a discussion of the possible statistical correlations between Ultra-High-Energy Cosmic-Ray (UHECR) directions in various models and structure in the galaxy distribution and whether or not this signal could be measurable.  This one is in the folder marked “High-Energy Astrophysical Phenomena“.

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

The second paper was published on Friday 23rd February and has the title “The IA Guide: A Breakdown of Intrinsic Alignment Formalisms” and the authors are: Claire Lamman (Harvard, USA);  Eleni Tsaprazi (Stockholm, Sweden);  Jingjing Shi (Tokyo, Japan); Nikolina Niko Šarčević (Newcastle, UK); Susan Pyne (UCL, UK); Elisa Legnani (Barcelona, Spain); and Tassia Ferreira (Oxford, UK). This one, which is in the folder marked Cosmology and NonGalactic Astrophysics, presents a review of Intrinsic Alignments, i.e. physical correlations involving galaxy shapes, galaxy spins, and larger scale structure, especially important for weak gravitational lensing

That concludes this week’s update!

Open Access Talk at UNSW

Posted in Biographical, Open Access, The Universe and Stuff with tags , , , on February 21, 2024 by telescoper

After an exciting start to the day involving a fire alarm and consequent evacuation of my hotel, I today ventured into the suburbs of Sydney via the Light Rail system (i.e. the tram) to the University of New South Wales. The tram ride took about 20 minutes from Central and, incidentally, took me right past the Sydney Cricket Ground. Anyway, the UNSW campus at Kensington is very impressive:

After a few gremlins with the WIFI connection, the talk I gave was a longer version of the one I did at the University of Sydney on Monday. In discussions with the Astrophysics group at UNSW, I found they were particularly unhappy about the decision of Monthly Notices of the Royal Astronomical Society to charge a high level of APC (Article Processing Artificial Profit Charge) so is looking at alternative journals that aren’t so exploitative. A journal has no right to call itself “open access” if it excludes researchers on grounds of cost. The problem with the Open Journal of Astrophysics in this case is that they need their publications to be in “high impact journals” for research assessment purposes, and OJAp doesn’t have an “official” journal impact factor yet. The fascination of bureaucrats with the obviously flawed journal impact factor disturbs me greatly but I hope we will have one soon so we may be able to help them out before too long.

Anyway, here are the slides from today’s talk:

Talking Down Under

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , on February 19, 2024 by telescoper

This morning I gave a short talk at the “Astronomy Tea” at the Sydney Institute for Astronomy. No prizes for guessing what I talked about. The talk was followed by questions and then by a huge thunderstorm.

Here are the slides:

P.S. Today was the first day of teaching of the new academic year at the University of Sydney, so the campus was much busier today than it has been.

New Publication at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , on February 16, 2024 by telescoper

It’s Saturday morning here in Sydney, which means it is time for another weekly update from the Open Journal of Astrophysics. In fact there is only one paper to report this week, being  the 13th paper in Volume 7 (2024)  and the 128th altogether. It was published on February 15th 2024.

The title is “Jet – counter-jet asymmetry in the jittering jets explosion mechanism of supernovae” and it  This one is in the folder called High-Energy Astrophysical Phenomena. The paper presents a discussion of the production of jets in core-collapse supernovae and the resulting formation of neutron stars, and the implications for the morphology of the supernova remnant.

The sole author of the paper is Noam Soker of Technion, Haifa, in Israel.

Here is the overlay of the paper containing the abstract:

New Publication at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , on February 12, 2024 by telescoper

With all the excitement of my first weekend in Sydney I completely forgot to post an update from the Open Journal of Astrophysics. In fact there is only one paper to report from last week, being  the 12th paper in Volume 7 (2024)  and the 127th altogether. This one was published on 9th February 2024 and is the first published from Down Under.

The title is “Galaxy Clusters Discovered via the Thermal Sunyaev-Zel’dovich Effect in the 500-square-degree SPTpol Survey” and it presents a catalogue of 689 galaxy clusters detected through the thermal Sunyaev-Zel’dovich using the dual-frequency polarization-sensitive camera SPTPol on the South Pole Telescope. This one is in the folder called Cosmology and NonGalactic Astrophysics.

This paper has lead author Lindsey Bleem  of the Argonne National Laboratory in the USA and has 127 other authors – too many to list individually here – but you can see them on the overlay below. I see quite a few names of people I know well!

Here is the overlay of the paper containing the abstract:

P.S. Incidentally, while I’m here I thought I’d share this little graphic I’ve generated (for other purposes) that shows how the rate of submissions to OJAp has increased over the last 5 years:

Two New Publications at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , on February 5, 2024 by telescoper

Now that I’m settled in Sydney it’s time to post another update relating to the  Open Journal of Astrophysics.  Since the last update we have published two more papers, taking  the count in Volume 7 (2024) up to 11 and the total published by OJAp up to 126. I should have posted these before leaving but it slipped my mind.

Both the current papers discussed here are in the folder marked Cosmology and NonGalactic Astrophysics, our most popular category.

Anyway, the first paper of the most recent pair – published on February 1st – is “LimberJack.jl: auto-differentiable methods for angular power spectra analyses”, Jaime Ruiz-Zapatero (Oxford, UK), David Alonso (Oxford, UK), Carlos García-García (Oxford, UK) , Andrina Nicola (Bonn, Germany), Arrykrishna Mootoovaloo (Oxford, UK), Jamie Sullivan (Berkeley, USA), Marco Bonici (Milan, Italy), and Pedro Ferreira (Oxford, UK). This paper presents a fully auto-differentiable code for cosmological analyses of two-point auto- and cross-correlation measurements from galaxy clustering, CMB lensing and weak lensing data written in Julia.

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

The second paper was published on Friday 2nd February and has the title “Can we constrain structure growth from galaxy proper motions?” which, as its title suggests, looks at the feasibility of using transverse peculiar velocities (i.e. proper motions) of galaxies for cosmological studies. The authors are Iain Duncan (Oxford, UK), David Alonso (Oxford, UK), Anže Slosar (Brookhaven National Laboratory, USA), and Kate Storey-Fisher (New York University, USA). To find out the answer to the question posed in its title you’ll have to read the paper!

Because of the high rate of publications coming out, we’re moving to a system where we register papers in batches once a week rather than individually as they are published. This is just a temporary measure until we can automate this process more fully. Anyway, you can expect another update in a week or so.

As the first month of 2024 is now over, I thought I’d post an update relating to the  Open Journal of Astrophysics.  Since the last update we have published two papers, taking  the count in Volume 7 (2024) up to 9 (the total for January) and the total published by OJAp up to 124. We will have others soon, but I will be travelling for the first few days of February so the next update will be in a week or so.

Using our sophisticated forecasting algorithm, based on the first month of 2024 as input, I predict that we will publish around 9×12=108 papers in 2024, more than double last year’s total of 50.

Both the current papers discussed here are in the folder marked Cosmology and NonGalactic Astrophysics, our most popular category.

Anyway, the first paper of the most recent pair – published on January 30th – is “Capse.jl: efficient and auto-differentiable CMB power spectra emulation”, by Marco Bonici (INAF Milano, Italy & Waterloo, Canada), Federico Bianchini (Stanford, USA) and Jaime Ruiz-Zapatero (Oxford, UK). This paper presents an emulator for rapid and accurate prediction of Cosmic Microwave Background (CMB) temperature, polarization, and lensing angular power spectra, that works much faster than traditional methods. The code is written in Julia, in which language we are seeing an increasing number of submissions to OJAp.

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

 

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.

The second paper was published yesterday (31st January 2024) and has the title “Cosmological Inflation in N-Dimensional Gaussian Random Fields with Algorithmic Data Compression” which is a  study of inflationary models with Gaussian random potentials for multiple scalar fields, tracking the evolutionary trajectories numerically. The authors are Connor Painter and Emory Bunn, both the Physics Department at the University of Richmond, Virginia (USA). Ted Bunn (as he is usually known) is a longstanding member of the Editorial Board of the Open Journal of Astrophysics (and was thereby excluded from any involvement in the editorial process for this paper).

Replacing Academic Journals

Posted in Open Access with tags , , on January 21, 2024 by telescoper

I just saw an interesting paper published by the Royal Society last year with the abstract:

Replacing traditional journals with a more modern solution is not a new idea. Here, we propose ways to overcome the social dilemma underlying the decades of inaction. Any solution needs to not only resolve the current problems but also be capable of preventing takeover by corporations: it needs to replace traditional journals with a decentralized, resilient, evolvable network that is interconnected by open standards and open-source norms under the governance of the scholarly community. It needs to replace the monopolies connected to journals with a genuine, functioning and well-regulated market. In this new market, substitutable service providers compete and innovate according to the conditions of the scholarly community, avoiding sustained vendor lock-in. Therefore, a standards body needs to form under the governance of the scholarly community to allow the development of open scholarly infrastructures servicing the entire research workflow. We propose a redirection of money from legacy publishers to the new network by funding bodies broadening their minimal infrastructure requirements at recipient institutions to include modern infrastructure components replacing and complementing journal functionalities. Such updated eligibility criteria by funding agencies would help realign the financial incentives for recipient institutions with public and scholarly interest.

https://royalsocietypublishing.org/doi/10.1098/rsos.230206

The article is well worth reading in full. It says things that I have said on this blog (e.g. here) but rather more eloquently than I managed. I’ll just make a couple of comments.

First, in the first paragraph of the first section it says:

Replacing traditional journals with a more modern solution is not a new idea […], but the lack of progress since the first calls and ideas more than 20 years ago has convinced an increasing number of experts that the time for small tweaks is long gone and a disruptive break is now overdue.

I agree, of course, and I think one of the problems is the perennial problem of academia: there’s a huge excess of talking over doing. With the Open Journal of Astrophysics I’m proud to be one of the doers. Incidentally, a senior member of the Royal Astronomical Society recently told me that they were finding OApJ “disruptive”. That is, of course, the point. We need a lot more disruption.

Another issue I’ve written about before is whether there is any future in academic journals as such at all. The concept dates from the 17th Century – when it was extremely valuable and useful – but is now very outdated. As I wrote here more than a decade ago:

I’d say that, at least in my discipline, traditional journals are simply no longer necessary for communicating scientific research. I find all the  papers I need to do my research on the arXiv and most of my colleagues do the same. We simply don’t need old-fashioned journals anymore.  Yet we keep paying for them. It’s time for those of us who believe that  we should spend as much of our funding as we can on research instead of throwing it away on expensive and outdated methods of publication to put an end to this absurd system. We academics need to get the academic publishing industry off our backs.

The revolution has been a slower process than I expected, but I do sense that the worm is at last turning.

Three New Publications at the Open Journal of Astrophysics

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

As promised yesterday, it’s time for a roundup of the week’s business at the  Open Journal of Astrophysics. This past week we have published three papers, taking  the count in Volume 7 (2024) up to 4 and the total published by OJAp up to 119. There are quite a few more ready to go as people return from the Christmas break.

In chronological order, the three 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 “Prospects for studying the mass and gas in protoclusters with future CMB observations” by  Anna Gardner and Eric Baxter (Hawaii, USA), Srinivasan Raghunathan (NCSA, USA), Weiguang Cui (Edinburgh, UK), and Daniel Ceverino (Madrid, Spain). This paper, published on 17th January 2024, uses realistic hydrodynamical simulations to probe the ability of CMB Stage 4-like (CMB-S4) experiments to detect and characterize protoclusters via gravitational lensing and the Sunyaev-Zel’dovich effect. This paper is in the category of Cosmology and Nongalactic 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 “SDSS J125417.98+274004.6: An X-ray Detected Minor Merger Dual AGN” and is by Marko Mićić, Brenna Wells, Olivia Holmes, and Jimmy Irwin (all of the University of Alabama, USA).  This presents the discovery of a dual AGN in a merger between the galaxy SDSS J125417.98+274004.6 and dwarf satellite, studied using X-ray observations from the Chandra satellite. The paper was also published on 18th January 2024 in the category Astrophysics of Galaxies . You can see the overlay here:

 

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

The last paper of this batch is  entitled “Population III star formation: multiple gas phases prevent the use of an equation of state at high densities” and the authors are:  Lewis Prole (Maynooth, Ireland), Paul Clark (Cardiff, UK), Felix Priestley (Cardiff, UK), Simon Glover (Heidelberg, Germany) and John Regan (Maynooth, Ireland). This paper, which presents a comparison of results obtained using chemical networks and a simpler equation-of-state approach for primordial star formation (showing the limitations of the latter) was published on 19th January 2024 and also in the folder marked Astrophysics of Galaxies.

Here is the overlay:

 

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

And that concludes the update. There’ll be more next week!
