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 four papers, bringing the number in Volume 9 (2026) to 126 and the total so far published by OJAp up to 574.
I will continue to include the posts made on our Mastodon account (on Fediscience); these announcements also show the DOI for each paper.
The first paper to report this week, published on Monday 15th June, is “SN 2025adpq: A Type Ia supernova in a collisional ring formed during a major galaxy merger” by Brendan O’Connor (Carnegie Mellon University, USA) and 18 others based in the USA, Germany and Australia. The study reports the discovery of a Type Ia supernova, SN 2025adpq, within a collisional ring formed by a major galaxy merger., offset from the nucleus of the primary galaxy. It is published in the folder Astrophysics of Galaxies.

The second paper for this week, published on Tuesday June 16th in the folder Astrophysics of Galaxies is “The Colors of Ices: Measuring ice column density through photometry” by Adam Ginsburg (U. Florida, USA) and ten others based in the USA, Germany and Spain. This study demonstrates that JWST photometry can identify and quantify interstellar ices, using new open-source models, interstellar ices, finding significant abundance in non-star-forming gas, suggesting many avenues for further research.

The third paper of the week, published on Wednesday 17th June in the folder Cosmology and Nongalactic Astrophysics is “The Non-Gaussian Weak-Lensing Likelihood: A Multivariate Copula Construction and Impact on Cosmological Constraints” by Veronika Oehl and Tilman Tröster (both of ETH Zurich, Switzerland). This study presents a framework for computing non-Gaussian likelihoods for correlation functions, particularly useful in large-scale weak-lensing surveys. It suggests Gaussian likelihoods are sufficient for stage-IV surveys.

The final, accepted version can be found on arXiv here and the Mastodon announcement is here:
The fourth and final paper of the week, also ublished on Wednesday 17th June but in the folder Astrophysics of Galaxies, is “Black Hole Feedback, Galaxy Quenching and Outflows at Cosmic Dawn: Analysis of the SEEDZ Simulations” by Lewis R. Prole (Maynooth University, Ireland) and 15 others based in Ireland, Germany, USA and UK. The study analyzes the growth and feedback effects of massive black holes in SEEDZ simulations, suggesting that black hole feedback, not nearby supernovae or gas exhaustion, limits initial growth.

And that concludes this week’s update. It has been another slow week on the publishing front, but the main reason is that we have a big backlog of papers accepted – about 10 of them – but still waiting for the authors to put their final versions on arXiv and we can’t do anything about that! I’ll do another update next Saturday.










Bayesian Inductive Inference and the Anthropic Cosmological Principle
Posted in The Universe and Stuff with tags Anthropic Cosmological Principle, Antony J.M. Garrett, Bayesian Inductive Inference, Comments on Astrophysics 17(1) 23-47, Gordon and Breach, NASA/ADS, Taylor and Francis on June 17, 2026 by telescoperMany moons ago I wrote a paper with a person called Anthony J.M. Garrett with the title Bayesian Inductive Inference and the Anthropic Cosmological Principle; the full reference is A.J.M. Garrett and P. Coles, Comments on Astrophysics 17(1) 23-47 (1993). It got a few citations here and there, and has been discussed in a few books and other texts. In 1999, the journal Comments on Astrophysics was merged with some other journals to form Comments on Modern Physics which was then acquired by publishers Taylor and Francis in 2001, when it took over Gordon and Breach. The new publisher never put the old papers online in digital format. Most of the back catalogue of Comments on Astrophysics is indexed in NASA/ADS (bibstem: ComAp), but No. 1 of Volume 17 is not there. That classic paper is not, as far as I know, available anywhere on the internet. Or at least it wasn’t until now.
I was recently asked for a PDF of the paper so I made a scan and sent it. Now that I have a scan, however, and WordPress now has a PDF upload gadget, I thought I’d put it up here. I did a Google search for it earlier this evening and the AI Summary described the paper as “seminal”, which just goes to show that AI isn’t always wrong!
Anyway, here is a scanned PDF of the paper:
Apologies that it’s a bit grubby and wonky, but the scan is made from an old photocopy. I did have a proper offprint somewhere, but I can’t find it.
The real reason for doing this post, however, is to use it as a counter-example to something people often bring up when I criticize academic publishers: “..but they curate the literature!”. They don’t, actually. Libraries do that. The Garrett-Coles paper is available as a hard copy in libraries, but the publisher has nothing to do with that!
P.S. I did a blog post a while ago based on part of the paper.
P.P.S. If I get time I’ll contact ADS to see if they want to put this up in the official biblipgraphic collection…
