It’s time for another Saturday 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 249 and the total so far published by OJAp up to 697.
I continue to include the posts made on our Mastodon account (on Fediscience); these announcements also contain a clickable form of the DOI for each paper. Our Mastodon account has regular updates and other announcements from OJAp too, including posts from the OJAp blog.
The first paper this week was published on Tuesday 20th October in the folder Astrophysics of Galaxies. The title is “The Metallicity Distribution of the Ultra-Faint Dwarf Galaxy Segue 1” by Daisy Bissonette (U. Chicago, USA) and 8 others based in the USA, Australia and Canada. The article explains that new data on the metallicity of ultra-faint dwarf galaxy Segue 1 reveal a continuous, short-duration episode of star formation and chemical enrichment, confirming its classification as a galaxy.

The second paper for this week, also published on Tuesday 20th October in the folder Astrophysics of Galaxies, “Ultraviolet diversity of Little Red Dots as a probe for direct-collapse black hole ages” by Elia Cenci & Melanie Habouzit (U. Geneva, Switzerland) and Dale D. Kocevski (Colby College, USA). This article uses simulations to explore UV emissions from galaxies hosting direct-collapse black holes (DCBHs), finding that these emissions evolve rapidly, reflecting changes in stellar mass and metal enrichment.

That concludes this week’s update. I had anticipate that we’ll pass the 250 mark this week, but business has been slower than of late so we’ll have to wait until next week for that. It is noticeable that the arXiv submission process is slower now than it used to be, presumably because of the huge influx of AI slop that the moderators have to deal with.
It’s Saturday again, so it’s time for another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further eight papers, bringing the number in Volume 9 (2026) to 245 and the total so far published by OJAp up to 693. There was no arXiv update on Monday 12th October owing to a US holiday, and I was on strike on Wednesday 14th October, so there were no papers published on either 13th or 14th October.

That concludes this week’s update. I anticipate that we’ll pass the 250 mark for 2026 next week, which means we’re well on target to publish over 300 papers and reach the 750 mark by the end of the year. I’ll do another update next weekend.
It’s Saturday again, so it’s time for another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further eight papers, bringing the number in Volume 9 (2026) to 237 and the total so far published by OJAp up to 685.

That concludes this week’s update. As things are going we seem likely to publish over 300 papers this year, and may reach the 750 mark by the end of the year too. I’ll do another update next week.
Today we published four papers at the Open Journal of Astrophysics all related to the Megatron Project which is co-led by Martin Rey of the University of Bath (UK), Harley Katz of the University of Chicago (USA) and Corentin Cadiou of the Institut d’Astrophysique de Paris in France. I will include this quartet in my regular weekly update on Saturday but there is a press release accompanying these publications so I thought I’d splash them a bit here too.
I’ll show the overlays on Saturday but in the meantime here are some pretty graphics from three of the papers:
New simulations connect the first stars to cosmic fingerprints still visible today
International MEGATRON project links space telescope observations of the infant Universe with the chemical fossil record of the Milky Way.
Researchers have used some of the most detailed simulations yet of the early Universe to investigate how the first stars and galaxies formed.
Led by researchers at the University of Bath, alongside collaborators at the University of Chicago in the US and the Institut d’Astrophysique de Paris in France, the MEGATRON project uses advanced simulations to explore how the first stars and galaxies lit up the previously dark cosmos and enriched it with the chemical elements that would later become the building blocks of everything around us.
Published today in the Open Journal of Astrophysics, four studies from the MEGATRON project combine cutting-edge cosmological simulations with sophisticated models of radiation, chemistry and galaxy formation. Together, these constitute the collaboration’s first substantial body of published results, with further papers expected to follow.
The findings from the study of the first stars show that accurately capturing the interplay between starlight, gas and newly forged elements is essential for connecting two previously separate views of the early Universe: observations of young galaxies by the James Webb Space Telescope (JWST) and the chemical clues preserved in ancient stars in and around the Milky Way – the galaxy that contains our Solar System.
JWST provides a direct view of galaxies in the infant Universe, while ancient stars act as a fossil record of cosmic history. By studying the chemical fingerprints of these ancient stars, astronomers can reconstruct the properties of the first stars and trace how they enriched the cosmos with the first chemical elements.
The simulations follow the evolution of a young galaxy that will eventually grow into a system similar in mass to the Milky Way. Using advanced computer models that simultaneously track the movement of gas, the propagation of starlight and the evolution of chemical concentrations, the team investigated how stars shape the gas in and around galaxies over billions of years.
The study suggests that simplified models may underestimate the influence of stellar radiation and complex chemical processes on the gas surrounding galaxies. By modelling these effects at exceptionally high resolution, the team resolved structures in the gas that are not captured by simpler models, helping to improve predictions for current and future astronomical observations.
A direct glimpse of the infant cosmos
Dr Martin Rey from the Department of Physics at the University of Bath and a lead contributor to the MEGATRON collaboration, said: “The James Webb Space Telescope gives us a direct glimpse of the infant cosmos, while stellar archaeology allows us to study the relics of those earliest times in our own Galactic neighbourhood. MEGATRON provides a physical bridge between the two.”
The simulations begin with pristine gas containing no heavy elements, mirroring conditions shortly after the Big Bang. They then follow the birth of the first stars, the radiation they emit, the supernova explosions that mark their deaths and the dispersal of newly forged elements into subsequent generations of stars and galaxies.
Understanding this process is central to one of astronomy’s most fundamental questions: where the elements that make up today’s Universe came from.
Dr Rey said: “The elements that make our world and life possible – carbon, oxygen, iron and many others – were forged by stars. To understand where those elements came from, we need to understand how the first stars formed and enriched their surroundings. MEGATRON allows us to test these ideas directly by comparing detailed simulations with observations from JWST and the chemical fingerprints preserved in ancient stars.”
Looking ahead, the team plans to use MEGATRON to strengthen links between theory and emerging observational data. As JWST continues to transform our understanding of the earliest galaxies, large-scale stellar surveys will provide increasingly detailed information about ancient stars in and around the Milky Way.
Dr Rey and his colleagues at Bath are already developing the next generation of simulations. The project has been awarded 40 million processor hours on the UK’s national supercomputers, equivalent to running five million laptops in parallel for a year. These resources will enable simulations with higher resolution and more complete physical models, allowing even more direct comparisons with JWST observations and the chemical fossil record preserved in ancient stars.
“MEGATRON provides a common physical framework for interpreting two of astronomy’s most exciting new datasets: JWST’s view of the earliest galaxies and the stellar fossil record,” said Dr Rey. “Together, these complementary observations allow us to test competing models of the first stars in ways that weren’t previously possible.”
The MEGATRON project started in 2023 and is scheduled to run until 2030.
It’s time once more for another Saturday update of activity at the Open Journal of Astrophysics. Since the last update we have published a further eight papers, including one correction to an article already published, bringing the number in Volume 9 (2026) to 217 and the total so far published by OJAp up to 664. This is the third week running that we have published 7 new papers.

That concludes this week’s update. I’ll just add a mention of yesterday’s post announcing that the Open Journal of Astrophysics is a Q1 Journal. It will be interesting to see if that stimulates another increase in submissions. As things are going we seem likely to publish about 300 papers this year. I’ll also mention that an exciting development is in the pipeline for next week, but I can’t say more until it happens.
It’s time once more for another Saturday update of activity at the Open Journal of Astrophysics. Since the last update we have published a further seven papers, bringing the number in Volume 9 (2026) to 209 and the total so far published by OJAp up to 656. This is the second week running that we have published 7 papers.
I continue to include the posts made on our Mastodon account (on Fediscience); these announcements also contain a clickable form of the DOI for each paper. Our Mastodon account has regular updates and other announcements from OJAp too.
The first paper this week was published on Monday 14th September in the folder Cosmology and Nongalactic Astrophysics. The title is “The Power of DESI for Photometric Redshift Calibration: A Case Study with KiDS-1000” and it is by Diana Blanco (UC Santa Cruz, USA) and 66 others distributed internationally. This study explores using the Dark Energy Spectroscopic Instrument (DESI) to calibrate photometric redshift distributions for gravitational lensing, which could improve understanding of dark energy and cosmic structure. In fact this paper was ready for publication a few months ago, but the first author left for another job before putting the final version on arXiv so it took a while to finish it.

That concludes this week’s update. At the rate we’re going we could well reach 300 by the end of the year, but we’ll just have to wait and see about that. I’ll do another next weekend.
It’s time once more for another Saturday update of activity at the Open Journal of Astrophysics. Since the last update we have published a further seven papers, bringing the number in Volume 9 (2026) to 202 and the total so far published by OJAp up to 649. This means that the total in Vol. 9 (2026) has now passed that of Vol. 8 (2025), with more than three months to go.
I continue to include the posts made on our Mastodon account (on Fediscience); these announcements also contain a clickable form of the DOI for each paper. Our Mastodon account has regular updates and other announcements from OJAp too.
The first paper this week was published on Monday 7th September in the folder Astrophysics of Galaxies. The title is “Not all cores are equal: Phase-space origins of dynamical friction, stalling and buoyancy” and the authors are Shashank Dattathri & Frank C. van den Bosch (Yale U., USA), Uddipan Banik (Princeton U., USA), Martin Weinberg (U. Mass., USA), Priyamvada Natarajan (Yale U., USA), Zhaozhou Li (Nanjing U., China) and Avishai Dekel (The Hebrew U., Israel). The paper describes how the distribution function of a galaxy, not just its central density gradient, influences the efficiency and direction of dynamical friction, affecting the movement of massive objects within it.

It is worth mentioning that there was one deferred arXiv mailing this week, due to the Labor Day holiday in the USA, so some papers were therefore published a day later than usual.
That concludes this week’s update. I’ll do another next weekend.
After a very busy week, it’s time once more for another Saturday update of activity at the Open Journal of Astrophysics. Since the last update we have published a further five papers, bringing the number in Volume 9 (2026) to 194 and the total so far published by OJAp up to 642. As explained at the end of this post, one of the five publications is a correction of an earlier paper.
I continue to include the posts made on our Mastodon account (on Fediscience); these announcements also show the DOI for each paper. The Mastodon account has regular updates and other announcements from OJAp too.

CORRECTION issued at the Open Journal of Astrophysics: "CORRECTION – DESI Data Release 1: Stellar Catalogue" by Koposov et al. (2026) (DOI:10.33232/001c.155260)
In the past when we have had minor correctionsto make we have simply asked the authors to create a new version, then when it has been checked, to place it on arXiv with a comment on the correction made. We then change the overlay to point to the new version with a comment on the change. I was recently advised, however, that best practice is to create a specific entry in Crossref for the corrected version, linked to the old one. Our Scholastica platform now has a mechanism to do this so from now on we will adopt this approach.
After a very busy week, it’s time once more for another Saturday update of activity at the Open Journal of Astrophysics. Since the last update we have published a further twelve papers, bringing the number in Volume 9 (2026) to 189 and the total so far published by OJAp up to 637. As I pointed out on Wednesday this week is the first during which we have published at least one paper in each of the six categories on astro-ph.
I continue to include the posts made on our Mastodon account (on Fediscience); these announcements also show the DOI for each paper. The Mastodon account has regular updates and announcements from OJAp too.
In the past on these posts I have included the article keywords as tags, but this is quite a lot of effort to do for little benefit so I’ve decided just to tag the arXiv category (i.e. folder) and arXiv ID for each paper as well as the lede from the journal platform.
The first one up this week was published on Monday 24th August 2026 in the folder Astrophysics of Galaxies. “Energy-Space Analysis of Tidal Stripping in Stellar-Dark Matter Systems“, by Bradley Arias (UC Berkeley, USA), Nicole E. Drakos (U. Hawaii, USA) and James E. Taylor (U. Waterloo, Canada), uses simulations to explore how tidal stripping shapes the stellar distribution of dwarf galaxies, also suggesting a pathway for the formation of galaxies deficient in dark matter
