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:

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.

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.

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.

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!
