Although it’s still holiday season for some, 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 four papers, bringing the number in Volume 9 (2026) to 171 and the total so far published by OJAp up to 619.
I 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 was published on Monday 10th August in the folder High-Energy Astrophysical Phenomena. “Search for neutrino emission from blazar γ-ray flares accounting for possible neutrino time delays” by Egor Podlesny & Foteini Oikonomou (Norwegian University of Science & Technology, Trondheim, Norway) investigates high-energy neutrino emissions associated with blazar flares, using data from IceCat-1, MOJAVE, CGRaBS, and Fermi-LAT. A slight correlation was found, consistent with the null hypothesis.

The second paper for this week, published on Tuesday 11th August in the folder Cosmology and Nongalactic Astrophysics is “The velocity coherence scale: a novel probe of cosmic homogeneity and a potential standard ruler” by Leonardo Giani (Swinburne University of Technology), Cullan Howlet (U. Queensland), Chris Blake (Swinburne), Ryan J. Turner (Australia National University) and Tamara M. Davis (U. Queensland) – all in Australia. This paper argues that velocity coherence scale, a measure that identifies the transition point of galaxy motion from correlated to anti-correlated, could potentially characterize the onset of cosmic homogeneity.

The third paper of the week, also published on Tuesday 11th Augus, but in the folder Astrophysics of Galaxies, is “A GLIMPSE of the 99%: a census of the faintest galaxies during the epoch of reionization and its implications for galaxy formation models” by Hakim Atek (Sorbonne Université, Paris, France) and 21 others based around the world.

The fourth and final paper of the week was published on Wednesday 12th August in the folder Astrophysics of Galaxies: “Dust and Grain Size Evolution in Galaxy Simulations: What Matters and What Does Not” by Massimiliano Parente & Desika Narayanan (U. Florida, USA) and Paul Torrey (U. Virginia, USA) presents the first implementation of an evolving dust grain size distribution within a model of galaxy evolution, successfully reproducing key observational constraints and exploring the mechanisms shaping galaxies.

That’s all for this week. We’re just ticking over at the moment, and steadily building up a backlog of papers to publish while we wait for authors to put their final versions on arXiv. I have a feeling there’s going to be a big splurge sometime. Will it be next week? We’ll find out next Saturday!
