Weekly Update from the Open Journal of Astrophysics – 07/03/2026
It’s Saturday once more, so it’s time for another update of activity at the Open Journal of Astrophysics. After a bumper week last week, this week has been slower on the publication side. Since the last update we have published a further two papers, bringing the number in Volume 9 (2026) to 47 and the total so far published by OJAp up to 495.
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 is “Comments on “Little ado about everything” by A. Lapi et al. and on cosmological back-reaction” by Julian Adamek (Universität Zürich, Switzerland). This was published on Wednesday 4th March 2026 in the folder Cosmology and Nongalactic Astrophysics. The author critiques A. Lapi et al.’s ηCDM model, arguing that their claim of accelerated universe expansion driven by density field fluctuations is implausible.

The second (and last) paper for this week is “Linear map-making with LuSEE-Night” by Hugo Camacho (Brookhaven National Laboratory, USA) and 34 others based in the USA, France, and the Netherlands. This was published on Thursday 5th March in the folder Instrumentation and Methods for Astrophysics. The paper discusses LuSEE-Night (the Lunar Surface Electromagnetics Experiment), a proposed lunar radio telescope using four antennas to map the sub-50 MHz sky with a 5-degree resolution, using the Wiener filter algorithm to manage systematic effects.

That concludes this week’s (brief update). Based on the number of papers accepted and waiting to be published it is likely we will pass 50 for the year and 500 in total by next week.
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!
