It’s Saturday once more, so it’s time for another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further four papers, bringing the number in Volume 9 (2026) to 51 and the total so far published by OJAp up to 499. I hoped we would reach 500 this week, but that milestone will have to wait. We have however passed the 50 mark for this year, so we have now published more papers so far in 2026 than we published in all of 2023.
I will continue to include the posts made on our Mastodon account (on Fediscience) to encourage you to visit it. Mastodon is a really excellent service, and a more than adequate replacement for X/Twitter (which nobody should be using); these announcements also show the DOI for each paper.
The first paper to report this week is “Effect of temperature on the structure of porous dust aggregates formed by coagulation” by Lucas Kolanz, Davide Lazzati and Job Guidos (Oregon State University, USA). This study uses 3D simulations to examine how temperature and monomer size distribution affect the structure of dust formed in supernovae at high redshift. It was published on Monday March 9th in the folder Astrophysics of Galaxies.

The second paper for this week is “Intrinsic alignment of disks and ellipticals across hydrodynamical simulations” by M. L. van Heukelum and N. E. Chisari (Utrecht University, The Netherlands). This is one of two papers published on Tuesday 10th March. This one is in the folder Astrophysics of Galaxies: it examines the inconsistent correlations between galaxy positions and shapes, comparing disk and elliptical shapes in different simulations. The results highlight the importance of sub-grid physics at non-linear scales.Abstractfor Intrinsic alignment of disks and ellipticals across hydrodynamical simulations.

Next one up is “A Comparison of Galacticus and COZMIC WDM Subhalo Populations” by Jack Lonergan (U. Southern California), Andrew Benson (Carnegie Observatories) and Xiaolong Du (UCLA), all based in the USA. This paper was published on 10th March 2026 in the folder Cosmology and Nongalactic Astrophysics. The study compares warm dark matter subhalo populations using the Galacticus model and COZMIC simulations, finding both can reliably reproduce these distributions, with Galacticus offering computational efficiency.Abstractfor A Comparison of Galacticus and COZMIC WDM Subhalo Populations.

And finally for this week we have “Simulation-Based Inference for Probabilistic Galaxy Detection and Deblending” by Ismael Mendoza (U. Maryland, USA) and 7 others (all based in the USA) on behalf of the LSST Dark Energy Science Collaboration. This was published on Thursday March 12th in the folder Instrumentation and Methods for Astrophysics. The article introduces the Bayesian Light Source Separator (BLISS), for detecting and measuring galaxy properties in wide-field cosmological surveys. BLISS demonstrates improved performance, particularly for faint and blended objects.

And that concludes this week’s update.
P.S. Thank you once again to the many people who have responded to the latest call for editors. I’ve been sending out invitations and getting people onboard as quickly as I can, but I still have a number to get to, so please bear with me!
