Four New Publications at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , , , , , on December 14, 2024 by telescoper

It’s Saturday morning once again so here’s another quick update of activity at the Open Journal of Astrophysics. Since the last update a week ago we have published  four papers, which takes the count in Volume 7 (2024) up to 114 and the total published altogether by OJAp up to 229. If we publish just one more paper between now and the end of the year, we will have published as many papers in 2024 as we have in all previous years.

Anyway, in chronological order of publication, 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 “Star formation beyond galaxies: widespread in-situ formation of intra-cluster stars” by Niusha Ahvazi & Laura V. Sales (UC Riverside, USA), Julio F. Navarro (U. Victoria, Canada), Andrew Benson (Carnegie Obs. USA), Alessandro Boselli (Aix Marseille U., France) and Richard D’Souza (Vatican Obs.). The paper, which is in the folder marked Astrophysics of Galaxies, The paper presents a simulation-based analysis of a diffuse star forming component in galaxy clusters extending for hundreds of kiloparsecs and tracing the distribution of neutral gas in the cluster host halo.

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, published on 10th December 2024 in the folder Cosmology and NonGalactic Astrophysics, is “Cosmological Constraints from Combining Photometric Galaxy Surveys and Gravitational Wave Observatories” by E.L. Gagnon, D. Anbajagane, J. Prat, C. Chang, and J. Frieman (all of U. Chicago, USA). This article quantifies the expected cosmological information gain from combining the forecast LSST 3x2pt analysis with the large-scale auto-correlation of GW sources from proposed next-generation GW experiments.

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

The third paper, also published on 10th December 2024, but in the folder marked Earth and Planetary Astrophysics, has the title “A potential exomoon from the predicted planet obliquity of β Pictoris b” and is written by Michael Poon, Hanno Rein, and Dang Pham all of the University of Toronto, Canada. It presents discussion, based on the β Pictoris system, of the idea that the presence of exomoons can excite misalignment between the spin and orbit axis (obliquity) in exoplanet systems

Here is the overlay

The final version accepted on arXiv is here.

Last of this quartet, published on 11th December 2024, and in the folder Cosmology and NonGalactic Astrophysics is “Map-level baryonification: Efficient modelling of higher-order correlations in the weak lensing and thermal Sunyaev-Zeldovich fields” and is by Dhayaa Anbajagane & Shivam Pandey (U. Chicago) and Chihway Chang (Columbia U.), all based in the USA.

The paper proposes an extension of the semi-analytic formalism to weak lensing and thermal Sunyaev-Zeldovich (tSZ) fields directly on the full-sky, with an emphasis on higher-order correlations. The overlay is here:

You can find the official accepted version on the arXiv here.

That’s all for this week. I’ll do another update next Saturday, and that will probably be the last one of the year. If we publish just one more paper between now and 31st December, we will have published as many papers in 2024 as we have in all previous years put together!

The Journal of Universal Rejection

Posted in Open Access on December 10, 2024 by telescoper

As (both) my regular readers know I have a strong interest in innovative publication methods, I thought I would share a very intriguing one I have just found out about:

I think this approach might help us at the Open Journal of Astrophysics cut our running costs still further. Gold Open Access journals have an incentive to publish as many papers as possible to increase revenue from Article Processing Charges, whereas we Diamond journals have an incentive in the opposite direction. This journal would appear to take that to its logical conclusion.

I think I’ll apply to be on the Editorial Board. It must be a very prestigious to bea member of the Editorial Board of a journal with such a high rejection rate!

Four New Publications at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , , , on December 7, 2024 by telescoper

It’s Satuday morning once again so here’s another quick update of activity at the Open Journal of Astrophysics. Since the last update a week ago we have published  four papers, which takes the count in Volume 7 (2024) up to 110 and the total published altogether by OJAp up to 225.

In chronological order of publication, 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 “The impact of feedback on the evolution of gas density profiles from galaxies to clusters: a universal fitting formula from the Simba suite of simulations” by Daniele Sorini & Sownak Bose (Durham University, UK), Romeel Davé (University of Edinburgh, UK), and Daniel Anglés-Alcázar (University of Connecticut, USA). The paper, which is in the folder marked Astrophysics of Galaxies, presents a study of the effects of stellar and/or AGN feedback on the shape and evolution of gas density profiles in galaxy haloes using the SIMBA simulations. It was published on Tuesday 3rd December 2024.

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, also published on 3rd December 2024, and is also the folder “Astrophysics of Galaxies, is “Self-regulated growth of galaxy sizes along the star-forming main sequence” by Shweta Jain (U. Kentucky, USA), Sandro Tacchella (U. Cambridge, UK) and Moein Mosleh (Shiraz University, Iran).  This paper suggestes an identification of a possible self-regulating mechanism in galaxy size growth involving the interplay between feedback from star formation and newly accreted gas.

You can see the overlay here:

 

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

The third paper, published on Thursday 6th December 2024 in the folder marked Cosmology and NonGalactic Astrophysics, is called  “BLAST: Beyond Limber Angular power Spectra Toolkit. A fast and efficient algorithm for 3×2 pt analysis” by Sofia Chiarenza, Marco Bonici & Will Percival (Waterloo, Canada) and Martin White (Berkeley, USA). It presents BLAST, an efficient algorithm for calculating angular power spectra without employing the Limber approximation or assuming a scale-dependent growth rate, based on the use of Chebyshev polynomials. The code is written in Julia.

Here is the overlay

 

 

The final version accepted on arXiv is here.

Last in this batch, published on 6th December 2024, and in the folder Astrophysics of Galaxies, is “On the universality of star formation efficiency in galaxies” by Ava Polzin & Andrey V. Kravtsov (U. Chicago) and Vadim A. Semenov & Nickolay Y. Gnedin (CfA Harvard), all based in the USA. The paper presents an argument that the universality of observational estimates of star formation efficiency per free-fall time can be plausibly explained by the turbulence-driven and feedback-regulated properties of star-forming regions.

You can find the official accepted version on the arXiv here.

We seem to have recovered from a small Thanksgiving lull and, looking at the OJAp workflow, I think we’ll have a similar number of publications next week. I’ll do another update next weekend!

New Publication at the Open Journal of Astrophysics

Posted in Maynooth, OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , on November 30, 2024 by telescoper

It’s Saturday morning once again so it’s time for the usual weekly update of publications at the Open Journal of Astrophysics. This week’s report will be short because, like last week, there is only one paper to report this week, being  the 106th paper in Volume 7 (2024)  and the 221st  altogether. It was published on Thursday 28th November 2024. We have some more papers in the publishing pipeline, which I thought might appear, but they didn’t come out this week possibily because of the Thanksgiving holiday in the USA.

Anyway, The title of the latest paper is “Growth of Light-Seed Black Holes in Gas-Rich Galaxies at High Redshift” by Daxal Mehta, John Regan and Lewis Prole (all of the National University of Ireland, Maynooth*. This paper presents a discussion of the rate of growth of black holes in the early Universe on the basis of simulations run using the Arepo code.

Here is the overlay of the paper containing the abstract:

Galactic Outflows

Posted in Open Access, The Universe and Stuff with tags , , , on November 22, 2024 by telescoper

We have a visiting speaker for a colloquium this afternoon in the form of Dr Martin Rey, formerly of Oxford University and now a lecturer at the University of Bath. Last night at dinner I learned that he has a YouTube channel called Cosmic Rey (geddit?) so I thought I’d share one of the videos here.

The paper relating to this video can be found on the arXiv here.

P.S. Martin has now joined the Editorial Board of the Open Journal of Astrophysics.

The Future of Diamond Open Access in Astrophysics

Posted in Biographical, Open Access with tags , , , , , , on November 17, 2024 by telescoper

The Open Journal of Astrophysics is now reasonably well established as a Diamond Open Access journal for the astrophysics community. We have published over a hundred articles so far this year at such a low cost that we can make our publications free to read and to publish. Thanks for all this is due to the volunteers on our Editorial Board, the excellent team at Maynooth University library, who have supported this project for 6 years, to the arXiv, as well of course to the authors who have chosen to publish with us.

Although we have established a good base, we’re still much smaller than the mainstream journals publishing just a few percent of their output. There is no sign of a slowdown at OJAp. Indeed there are signs that pace will pick up. I heard last week, for example, that Oxford University Press (the publisher of Monthly Notices of the Royal Astronomical Society) has decided to cancel the ‘Read-and-Publish’ agreement that allowed authors from Australian institutions to avoid APCs. I imagine we’ll get quite a few more submissions from Down Under thanks to that decision.

Nevertheless, we’ve a long way to go to catch up with the likes of A&A, MNRAS and ApJ in terms of numbers. If activity continues to grow then we will incur greater costs – our provider, Scholastica, charges us per paper. Those costs will still be smaller than regular journals, but I think it’s unfair that the expense of running a journal that serves the global astrophysics community should fall entirely on one small University in Ireland.

Expense is only one issue. I never envisaged that OJAp would be unique. It was more intended to be a proof of concept. I would like to see a range of Diamond Open Access journals offering a choice for authors and serving different sub-disciplines. Most universities nowadays have publishing operations so there could be network of federated journals, some based on arXiv and some based on other repositories. Perhaps institutions are worried about the expense but, as we have shown the actual cost, is far less than they are wasting on Article Processing Charges. I rather think it’s not the money that is the issue, just the unimaginatively risk-averse thinking in what passes these days for university management.

There are two simple – but not mutually exclusive – possibilities.

One is that astrophysics institutions club together and donate funds not only to keep OJAp going, but also to allow us to invest in improvements. A donation equivalent to the cost of just one APC for a typical journal would help us enormously. We do actually get some donations already, but more would always be welcome. In the long run, an investment in Diamond Open Access would pay back many times in savings; OJAp has already saved the worldwide community over £500,000.

The other is that other members of the community follow the lead of OJAp and set up their own journals. I wouldn’t see others as much as competitors, more as allies with community-led federated system. In the light of the OUP decision mentioned above, why don’t Australian research institutions set up their own version of OJAp? I’d be happy to discuss how to start up such a journal with anyone interested.

If you would like to discuss either of these possibilities please use the comment box below or email me here.

P.S. There is another issue concerning the future of OJAp, which is that I will be retiring in a few years, but now isn’t the time to discuss that one!

Two New Publications at the Open Journal of Astrophysics

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

Once again it’s time for a Saturday morning update on activity at the  Open Journal of Astrophysics.  Since the last update we have published two more papers, taking  the count in Volume 7 (2024) up to 104 and the total published by OJAp up to 219.

The first paper of the most recent pair, published on November 13 2024,  in the folder Cosmology and NonGalactic Astrophysics, is “Stochastic Super-resolution of Cosmological Simulations with Denoising Diffusion Models” by Andreas Schanz, Florian List and Oliver Hahn (all based in the University of Vienna, Austria). It presents a  discussion of denoising diffusion in generative models for achieving super-resolution in simulations of cosmic large-scale structure.

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

Once again it’s time for a quick update of activity at the Open Journal of Astrophysics. Since the last update a week ago we have published  four papers, which takes the count in Volume 7 (2024) up to 102 and the total published altogether by OJAp up to 217.   This means not only that we have reached a century for the year but also that so far in 2024 we have published more than double the number of papers that we published in all of 2023. I blogged about the significance of the figure 217 here.

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 generative model for Gaia astrometric orbit catalogs: selection functions for binary stars, giant planets, and compact object companions” by Kareem El-Badry (Caltech, USA), Casey Lam (Carnegie Observatories), Berry Holl & Jean-Louis Halbwachs (U. Geneva), Hans-Walter Rix (MPA Heidelberg, Germany), Tsevi Mazeh (Tel Aviv, Israel) and Sahar Shahaf (Weizmann Institute of Science, Israel). This one is in the folder Solar and Stellar Astrophysics. The paper presents a forward method for estimating the selection function (i.e. the probability of a system with a given set of parameters being included in a catalog). It was published on November 4th 2024.

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, published on 5th November 2024. is “Primordial magnetogenesis in a bouncing model with dark energy” by Marcus V. Bomfim (Rio de Janeiro, Brazil), Emmanuel Frion (Western U. Canada), Nelson Pinto-Neto (Espírito Santo, Brazil), and Sandro D. P. Vitenti (Paraná, Brazil). This paper, in the section on Cosmology and NonGalactic Astrophysics, presents a discussion of the possible generation of magnetic fields on cosmological scales by in a model involving a scalar field coupled to electromagnetism

You can see the overlay here:

 

 

 

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

The third paper, published on 6th November 2024 in the folder marked Astrophysics of Galaxies, is called  “Evidence for large scale compressible turbulence in the ISM of CSWA13, a star-Forming Lensed Galaxy at z = 1.87 with outflowing wind” by Itzhak Goldman (Tel Aviv, Israel). It presents a statistical analysis of the spatial distribution and kinematics of nebular gas with discussion of the nature of the turbulence present.

That’s all for now. I will post another update in a week.

Saving Money via Diamond Open Access

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

This morning I published a paper at the Open Journal of Astrophysics that brought the total number of publications there to 217. That may not seem a very significant number but I’ve had it in the back of my mind for some time. Some time ago Monthly Notices of the Royal Astronomical Society (MNRAS) decided to go Gold Open Access, charging a baseline APC of £2310 per article. I know that cost is not paid directly by authors from institutions with Read and Publish agreements with Oxford University Press (the publisher ofn MNRAS) but that doesn’t mean that it’s free: funds are still siphoned off from library budgets.

Anyway, taking the indicative cost of an APC to be the £2310 charged by MNRAS – some journals charge a lot more – the fact that we have published 217 papers means we have now saved the astronomical community around 217 × £2310 which is over £500k (€600k) in APCs. The cost to us is just a few percent of that figure.

The issue of University funding is a very live one in England, in Ireland and in The Netherlands. None of the financial crises can be solved completely by moving away from APCs but there is no justification at all for continuing to hand millions per year out of a shrinking pot over to greedy publishers. Surely this is an excellent time for Higher Education Institutions collectively to make a decisive move in the direction of Diamond Open Access?
