This week we have published four papers at the Open Journal of Astrophysics, which I now present to you here. These four take the count in Volume 7 (2024) up to 60 and the total published altogether by OJAp up to 175. It is gratifying to see the range of high-quality papers published steadily increasing. We are getting several papers submitted every day now.
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 population of neutron star candidates in wide orbits from Gaia astrometry” by Kareem El-Badry (Caltech, USA) and 12 others based across the world. The paper presents a spectroscopic study of neutron star candidates identified using GAIA astrometry to be in wide binary orbits around main sequence stars, was published on 15th July 2024 and is in the folder marked Solar and Stellar Astrophysics. For more information about this one, see here.
Here is a screen grab of the overlay, which includes the abstract:

The second paper to announce is “Systematic Effects in Galaxy-Galaxy Lensing with DESI” and was written by Johannes Ulf Lange (University of Michigan, Ann Arbor, USA) and 58 others, again distributed internationally. This one reports a study of systematic effects (such as incompleteness and intrinsic alignment) on galaxy-galaxy lensing results from the Dark Energy Spectroscopic Instrument (DESI) survey. This one is in the folder called Cosmology and NonGalactic Astrophysics and was published on 16th July 2024.

The next paper is also in the folder called Cosmology and NonGalactic Astrophysics. It is entitled “Unleashing cosmic shear information with the tomographic weak lensing PDF” and is by by Lina Castiblanco (Newcastle Univresity, UK), Cora Uhlemann (Bielefeld University, Germany), Joachim Harnois-Déraps (Newcastle University, UK) and Alexandre Barthelemy (Ludwig-Maximilians-Universität, Germany). This one was published on 17th July 2024.

Last but by no means least, published on 18th July 2024, we have a paper entitled “When to interfere with dark matter? The impact of wave dynamics on statistics“. The primary classification for this one is again Cosmology and Nongalactic Astrophysics and it discusses the imprint of wave-mechanical behaviour, perhaps associated with ultra-light scalar field dark matter on the statistical properties of large-scale structure. The authors are Alex Gough (Newcastle University, UK) and Cora Uhlemann (Bielefeld University, Germany; who also featured in the author list of the previous paper). This is a paper close to my own interests, but because I know both authors well and was the PhD examiner of the first author I thought it best to recuse myself from an editorial role on this one.

It did look likely at one stage that we might publish a paper every day last week, but the final version of one other paper didn’t make it onto arXiv in time to be announced on Friday so I will publish that one on Monday.
