New Publication at the Open Journal of Astrophysics!

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , on September 15, 2020 by telescoper

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.

Here is a screen grab of the overlay:

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

You can find the arXiv version of the paper here.

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.

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!

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.

Proving further the point that the The Open Journal of Astrophysics is definitely fully open we have published yet another paper. This one was actually published yesterday, which means that we had two in two days..

This one is in the Cosmology and Nongalactic Astrophysics section and is entitled Source Distributions of Cosmic Shear Surveys in Efficiency Space. The authors are Nicolas Tessore and Ian Harrison, both from the University of Manchester. The paper is concerned with the extraction of cosmological information from cosmic shear surveys.

Well, Maynooth University may well be still (partially) closed as a result of the Covid-19 pandemic but the The Open Journal of Astrophysics is definitely fully open.

In fact we have just published another paper! This one is in the Astrophysics of Galaxies section and is entitled A Bayesian Approach to the Vertical Structure of the Disk of the Milky Way. The authors are Phillip S Dobbie and Stephen J Warren of Imperial College, London.

Here is a screen grab of the overlay:

I’d like to take this opportunity to thank the Editorial team and various referees for their efforts in keeping the Open Journal of Astrophysics going in these difficult times.

Well Maynooth University may have been closed by the Coronavirus but the The Open Journal of Astrophysics certainly has not!

In fact we have just published another paper! This one is called Discrete Chi-square Method for Detecting Many Signals and the author is Lauri Jetsu of the University of Helsinki in Finland.

Here is a grab of the overlay as it appears on my phone:

Well Maynooth University may have shut down but the The Open Journal of Astrophysics certainly has not.

In fact we have just published another paper! This one is called Halo Spins from Primordial Inner Motions and the first author is Mark Neyrinck (based in Bilbao). The other authors are Miguel Aragon-Calvo (based in Mexico), Bridget Falck and Alex Szalay (based in the USA) and Jie Wang (China).

Here is a grab of the overlay:

As an added bonus there are some groovy videos to go with this paper:

You might have to read the paper, however, to understand exactly what they mean (although they are very pretty anyway).

It’s two in two days because we have published another new paper at The Open Journal of Astrophysics. The title is A Beginner’s Guide to working with Astronomical Data. Here is a grab of the overlay:

You can find the arXiv version of the paper here.

The author is Markus Pössel of the Haus der Astronomie at the Max Planck Institute for Astronomy in Heidelberg (Germany). This is a long paper – 71 pages with over a hundred figures – that gives a comprehensive introduction to the various kinds of astronomical data and techniques for working with such data. I think this paper will attract a lot of interest from many different kinds of people but it will be particularly interesting to students doing undergraduate projects involving astronomical data (and their supervisors).

Another point worth noting is that there’s a small addition to the overlay for this paper, which will apply to all future papers (and retrospectively once we have worked through the back catalogue) and that is in the bottom left of the image above. It shows that the article is published with the latest form of Creative Commons License (CC-BY-4.0). It has always been our policy to publish under a CC-BY licence but Scholastica have very helpfully set up a new facility to make this explicit on each page. This is part of our efforts to ensure that we are compliant with Plan S which makes CC-BY licenses mandatory.

UPDATE: the CC-BY-4.0 license has now been applied retrospectively to all our publications.
