New Publication at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , on February 2, 2021 by telescoper

Time to announce the first publication of 2021 in the Open Journal of Astrophysics. This one was actually published a few days ago but  it took a bit of time to get the metadata and DOI registered so I held off announcing it until that was done.

The latest publication is a lengthy and comprehensive review article (67 pages altogether) by Allahverdi et al. which has 26 authors from all round the world. It is entitled The First Three Seconds: a Review of Possible Expansion Histories of the Early Universe and is a study of the various possible evolutionary histories of cosmic expansion possible with a wide range of cosmological models with their implications for baryogenesis, nucleosynthesis, primordial gravitational wave production, and many other things besides.

Here is a screen grab of the overlay:

And so Volume 4 begins. Volume 3 had 15 papers, Volume 2 had 12 , and Volume 1 just 4 so we’re growing slowly but surely! Let’s see how many we publish in 2021. I can tell you  we have some very exciting papers in the pipeline…

New Publication at the Open Journal of Astrophysics

Just time before Christmas to announce another paper in the Open Journal of Astrophysics. This one was actually published a few days ago but because of holiday delays it took some time to get the metadata and DOI registered so I held off announcing it until that was done.

The latest publication is by my colleague* John Regan (of the Department of Theoretical Physics at Maynooth), John Wise (Georgia Tech), Tyrone Woods (NRC Canada), Turlough Downes (DCU), Brian O’Shea (Michigan State) and Michael Norman (UCSD). It is entitled The Formation of Very Massive Stars in Early Galaxies and Implications for Intermediate Mass Black Holes and appears in the Astrophysics of Galaxies section of the arXiv.

Here is a screen grab of the overlay:

I think that will be that for for 2020 at the Open Journal of Astrophysics. We have published 15 papers this year, up 25% on last year. Growth is obviously modest, but there’s obviously a lot of inertia in the academic community. After the end of this year we will have two full consecutive years of publishing.

I’d like to take this opportunity to thank all our authors, readers, referees, and editors for supporting the Open Journal of Astrophysics and wish you all the very best for 2021!

*Obviously, owing to the institutional conflict I recused myself from the editorial process on this paper.

The Christmas rush is definitely upon us and papers are queuing up to be published in the Open Journal of Astrophysics. The latest publication is by Tom Kitching and Anurag Deshpande of MSSL (University College London) and Peter Taylor of JPL (Caltech). It is entitled Propagating residual biases in masked cosmic shear power spectra. This is another one for the folder marked Cosmology and Nongalactic Astrophysics.

Here is a screen grab of the overlay:

When I last posted about a new OJA paper I mentioned that it seemed to be taking authors longer than usual to make revisions. There are signs now that some authors are trying to get papers off their desk before the Christmas break so we may have two or three more to publish before the year is out.

P.S. Last week I received an offer from a commercial organization to buy the Open Journal of Astrophysics. I replied politely that it is not for sale.

New Publication at the Open Journal of Astrophysics!

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , on December 10, 2020 by telescoper

Time to announce another new paper in the Open Journal of Astrophysics. The latest publication is by Johan Comparat and 27 others – too numerous to list individually here –  and is entitled Full-sky photon simulation of clusters and active galactic nuclei in the soft X-rays for eROSITA. This is another one for the Cosmology and Nongalactic Astrophysics folder.

This paper is closely connected to the eROSITA instrument which is why it involves a considerable number of authors in different institutions – the current record length for an OJAp author list – though this is by no means a large collaboration by the standards of astrophysics and cosmology! It’s good to see some big names in there though!

With this paper we have exceeded the number of papers published last year. We do in fact have quite a few in the pipeline but owing to the ongoing pandemic there have been some refereeing delays and in some cases authors are taking more time than expected to do the “revise and resubmit” routine. I think there are plenty of other people around who are just as tired as I am! Perhaps we’ll see a clutch emerging in the New Year!

Time to announce another new paper in the Open Journal of Astrophysics. The latest publication is by Amy Louca and Elena Sellentin, both of the Sterrewacht Leiden in the The Netherlands, and is entitled The impact of signal-to-noise, redshift, and angular range on the bias of weak lensing 2-point functions. This is another one for the Cosmology and Nongalactic Astrophysics folder.

Here is a screen grab of the overlay:

We actually published this one a few days ago but there was a slight delay registering the metadata and also I was very busy, so this post is a little late. With this paper, we have published as many papers so far in 2020 as we did in 2019 so with several more in the pipeline this looks like being our busiest year

A day may come when I don’t write a blog post every time we publish a new paper in the Open Journal of Astrophysics, but it is not this day…

Today’s new publication is by Liliya Williams (of the University of Minnesota, Twin Cities) and David Zegeye of the University of Chicago and is entitled Two-component mass models of the lensing galaxy in the quadruply imaged supernova iPTF16geu.

Incidentally, you may notice that Scholastica have added MathJax to the platform to render mathematical expressions in the abstract.

Another new paper  has been published in the Open Journal of Astrophysics! This is another for the folder marked Cosmology and Nongalactic Astrophysics and is entitled Low-scatter galaxy cluster mass proxies for the eROSITA all-sky survey.

The authors of this paper are Dominique Eckert of the University of Geneva, Alexis Finoguenov (Helsinki), Vittorio Ghirardini (MPE Garching), Sebastian Grandis (LMU), Florian Käfer (MPE Garching), Jeremy Sanders (MPE Garching) and Miriam Ramos-Ceja (MPE Garching).

For those of you unfamiliar with eROSITA, it is an X-ray instrument that was built at the Max Planck Institute for Extraterrestrial Physics, where several of the authors work.

So another new paper has been published in the Open Journal of Astrophysics! This one is in the folder marked Astrophysics of Galaxies and is entitled Massive Star Formation in Metal-Enriched Haloes at High Redshift. I should explain that “Metal” here is the astrophysicist’s definition which basically means anything heavier than hydrogen or helium: chemists may look away now.

The authors of this paper are John Regan (of the Department of Theoretical Physics at Maynooth University), Zoltán Haiman (Columbia), John Wise (Georgia Tech), Brian O’Shea (Michigan State) and Michael Norman (UCSD). And before anyone asks, no I don’t force members of staff in my Department to submit papers to the Open Journal of Astrophysics and yes I did stand aside from the Editorial process because of the institutional conflict.

Another new paper has been published in the Open Journal of Astrophysics! This one was actually published last Friday but it being the Bank Holiday weekend I just got round to blogging about it today. This is another one for the Cosmology and NonGalactic Astrophysics section. It’s called Cosmic event horizons and the light-speed limit for relative radial motion and is a sort of pedagogical review of the subject aimed at dispelling some common misconceptions about radial velocities and horizons. The author is Markus Pössel of the Max Planck Institute for Astronomy at Heidelberg.

Here is a screen grab of the overlay:

I’ve taken the liberty of adding the background teaser image in full here, as it is rather groovy:

New Publication at the Open Journal of Astrophysics!

Posted in OJAp Papers, Uncategorized with tags , , , , on July 29, 2020 by telescoper

To celebrate yesterday’s news, I have great pleasure today in publishing another paper in The Open Journal of Astrophysics.

A reason to be especially pleased with this article is that this is our first publication in the Solar and Stellar Astrophysics category of astro-ph. It’s good to be spreading out beyond cosmology and extragalactic astrophysics which is where most of our papers appear.

The intriguing title of the latest paper is The one that got away: a unique eclipse in the young brown dwarf Roque 12. There’s also a blog post by one of the authors that tells the fascinating behind-the-scenes story of this paper.

The authors of the paper are Aleks Scholz (University of St Andrews, UK), Dirk Froebrich (University of Kent, Canterbury, UK); Koraljka Muzic (University of Lisbon, Portugal) and Jochen Eislöffel (TLS Tautenburg, Germany).

Here is a screen grab of the overlay:

You might notice that we now have the volume number appearing on the overlay, a change we requested recently from Scholastica.

You can find the arXiv version of the paper here.
