New Publication at the Open Journal of Astrophysics

It’s time to announce yet another new paper at the Open Journal of Astrophysics.

The latest paper is the 9th paper in Volume 6 (2023) and the 74th in all. This one is another one for the folder marked Instrumentation and Methods for Astrophysics. The title is “panco2: a Python library to measure intracluster medium pressure profiles from Sunyaev-Zeldovich observations”. The code described in the paper The Python code is available on GitHub and there isextensive technical documentation to complement this paper.

The authors are Florian Kéruzoré (Argonne National Laboratory, USA, and the University of University of Grenoble, France), Frédéric Mayet, Emmanuel Artis, Juan-Francisco Macías-Pérez, Miren Muñoz-Echeverría and Laurence Perotto (all of the University of Grenoble, France) and Florian Ruppin (of the University of Lyon, also in France).

It’s time to announce yet another new paper at the Open Journal of Astrophysics Open Journal of Astrophysics. This was published last week (on 15th February 2023) but there was a slight delay in getting the DOI activated and all the metadata registered so I waited until that was done before announcing the paper here.

The latest paper is the 8th paper in Volume 6 (2023) as well as the 73rd in all. This one is another one for the folder marked Cosmology and Nongalactic Astrophysics. The title is “The N5K Challenge: Non-Limber Integration for LSST Cosmology”. The paper is about ways of avoiding using the ubiquitous Limber Approximation which, I discovered this morning, is now 70 years old, Nelson Limber’s original paper on the subject having been published in January 1953.

The lead author of the paper is Danielle Leonard of Newcastle University and there are ten co-authors from around the world in countries including UK, USA, Brazil, Germany, Spain, Switzerland and France on behalf of the LSST Dark Energy Science Collaboration.

New Publication at the Open Journal of Astrophysics

It’s time to announce another new paper at the Open Journal of Astrophysics. This was published yesterday (13th February 2023). The rate of submissions has increased greatly in recent weeks, so  I am thinking seriously about switching to a weekly round-up on here instead of individual posts, but for the meantime I’ll carry on.

The latest paper is the 7th paper in Volume 6 (2023) as well as the 72nd  in all. This one is another one for the folder marked Instrumentation and Methods for Astrophysics. The title is “FRBSTATS: A web-based platform for visualization of fast radio burst properties”. This paper describes a software platform which can be accessed directly here. If you want to read more about Fast Radio Bursts, you can look here.

The authors of the paper are Apostolos Spanakis-Misirlis, who gives his affiliations as the University of Piraeus and University of Crete (Greece), and Cameron Van Eck of ANU in Canberra, Australia

New Publication at the Open Journal of Astrophysics

We’re on a bit of a roll at the Open Journal of Astrophysics and it’s time to announce yet another paper. We actually published this one yesterday (7th February 2023), which makes it two in two days. I don’t think we’ll keep up that rate but we have seen a big increase in submissions recently and these are working their way through the system very nicely. We aim to publish accepted papers within a day of the revised version appearing on arXiv.

The latest paper is the 6th paper in Volume 6 (2023) as well as the 71st in all. This one is another one for the folder marked Cosmology and Nongalactic Astrophysics. The title is “Almanac: Weak Lensing power spectra and map inference on the masked sphere”. The nub of the problem addressed by this paper is that the usual statistical analysis of data presented in projection on the sky involves spherical harmonics, which are orthogonal functions on the celestial sphere, but when the sky is not completely covered (i.e. part of it is masked), these functions are not orthogonal on what remains.

The authors of this paper are Arthur Loureiro (University of Edinburgh, UK), Lorne Whiteway (University College London, UK), Elena Selentin (Leiden University, NL), Javier Silva Lafaurie (Leiden University, NL), Andrew Jaffe (Imperial College London, UK) and Alan Heavens (Imperial College London, UK)

Well, it may be a Bank Holiday here in Ireland but there’s no break for the Open Journal of Astrophysics and it’s time to announce yet another paper hot off the press.

The latest paper is the 5th paper in Volume 6 (2023) as well as the 70th in all. This one is in the folder marked Instrumentation and Methods for Astrophysics. The title is “PSFs of coadded images”; for those of you not up with the lingo, “PSF” stands for point spread function.

The authors of this paper are Rachel Mandelbaum (1), Mike Jarvis (2), Robert H. Lupton (3), James Bosch (3), Arun Kannawadi (3), Michael D. Murphy (1) and Tianqing Zhang (1) and the LSST Dark Energy Science Collaboration. The affiliations of the individual authors are: (1) Carnegie Mellon University, Pittsburgh PA; (2) University of Pennsylvania, Philadelphia PA; (3) Princeton University, Princeton NJ; all in the USA of course.

New Publication at the Open Journal of Astrophysics

The articles are coming in thick and fast at the Open Journal of Astrophysics. and why trying to get them refereed and published as quickly as we can. It’s time to announce yet another paper. This one was published officially yesterday (2nd February 2023) but I just found time to post about it here today before I go to my 9am tutorial.

The latest paper is the 4th paper in Volume 6 (2023) as well as the 69th in all. This one is in the Astrophysics of Galaxies folder.

The latest publication is entitled “Wide Binaries from GAIA EDR3: preference for GR over MOND?”.  The authors of this paper,  Charalambos Pittordis and Will Sutherland, are both based at Queen Mary, University of London. We published a related paper last month.

P.S. You may be wondering about the image shown in the overlay. This paper doesn’t contain any figures or images so I tried out the collection of stock photographs that comes free with the Scholastica platform by typing in “gauge”. The result was a quite amusing collection of pictures of various kinds of dials and other gauges. I quite liked the one above so used it just for show!

New Publication at the Open Journal of Astrophysics

Continuing the process of catching up with business at the Open Journal of Astrophysics, here is the first paper of 2023. This one was accepted before Christmas but the final version only appeared on arXiv after the holiday and was published officially on 4th January 2023.

The latest paper is the first paper in Volume 6 (2023) as well as the 66th in all. It’s yet another in the Cosmology and Non-Galactic Astrophysics folder.

The latest publication is entitled “It takes two to know one: Computing accurate one-point PDF covariances from effective two-point PDF models“. This is a British-French-German collaboration led by Cora Uhlemann of Newcastle University with co-authors  Oliver Friedrich, Aoife Boyle, Alex Gough, Alexandre Barthelemy, Francis Bernardeau, and Sandrine Codis.

This is such an interesting paper that we discussed it at our cosmology journal club at Maynooth University a while ago when it first appeared on arXiv and reading it again since then has suggested a nice project to me!

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

New Publication at the Open Journal of Astrophysics

I’ve been catching up on publishing matters over the past day or so, including dealing with a bit of a backlog generated by the Christmas break. The Open Journal is run entirely by volunteers and we all need some time off at some point.

To start with I’m delighted to be able to announce the last paper of 2022 at the Open Journal of Astrophysics.  The latest paper is the 17th paper in Volume 5 (2022) as well as the 65th in all. It’s yet another in the Cosmology and Non-Galactic Astrophysics folder.

The latest publication is entitled “The Cosmic Graph: Optimal Information Extraction from Large-Scale Structure using Catalogues“. It is written by a distinguished collection of cosmologists from around the world (and Alan Heavens).
