Weekly Update from the Open Journal of Astrophysics 08/08/2026
Although it’s 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 167 and the total so far published by OJAp up to 615.
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 Tuesday 4th August in the folder Astrophysics of Galaxies with the title “Small-scale turbulence alongside large-scale turbulence in a z=1.87 star-forming galaxy with an outflowing wind, revealed by multi-point structure functions” by Itzhak Goldman (Afeka College, Israel). A previous study by the author found evidence of large and small scale turbulence in the star-forming galaxy CSWA13, suggesting that star clusters and large clumps within the galaxy could be driving this turbulence.

The second paper for this week, published on Thursday 6th August in the folder Astrophysics of Galaxies, is “From Clumps to Sheets: Geometry Controls the Temperature PDF of Multi-Phase Gas” by Zirui Chen and S. Peng Oh (UC Santa Barbara, USA). This study uses 3D hydrodynamic simulations to show that the temperature probability distribution functions (PDFs) of multi-phase turbulent gas differ significantly under interstellar medium (ISM) and circumgalactic medium (CGM) conditions.
The overlay looks like this:

The third paper of the week, published on Thursday 6th August in folder Instrumentation and Methods for Astrophysics is “First Detection of Extensive Air Showers Using a Small-Aperture Fluorescence Telescope” by M. Zotov (M.V. Lomonosov Moscow State University, Russia) and 7 others based in Russia and Armenia. The study reports the first-ever detection of extensive air showers from ultra-high-energy cosmic rays using a compact fluorescence telescope, employing both conventional and deep learning analysis methods.

The fourth and final paper of the week was published on Friday 7th August in the folder Cosmology and Nongalactic Astrophysics: “TDCOSMO XXVI: Uniform Lens Modeling of Eight Doubly Imaged Quasars“, by Ryan Brady (Stony Brook University, USA) and 9 others based all around the world, presents a new method for analyzing doubly imaged quasars using the Hubble Space Telescope, revealing that arc surface brightness is key to precision in mass model measurements.

That’s all for this week. We have about a dozen more papers accepted and waiting for the authors to put the final version on arXiv, which they will presumably do when they’re back from holiday. I’ll do an update next weekend and we’ll see!

A Supernova in Motion
In 1604, astronomers first caught sight of Kepler’s Supernova Remnant, a massive explosion some 17,000 light-years away. Twenty-five years of observations from the Chandra X-ray Observatory went into making this timelapse, which shows the supernova remnant‘s material pushing into the surrounding gas and dust.
In its fastest regions, the supernova remnant is moving around 2% of the speed of light–some 22 million kilometers per hour. Slower parts of the remnant are moving at just 0.5% of light-speed. (Image credit: NASA/CXC/SAO/Pan-STARRS; via Gizmodo)

The Best of FYFD 2025
Happy 2026! This will be a big year for me. I’ll be finishing up and turning in the manuscript for my first book — which flows between cutting edge research, scientists’ stories, and the societal impacts of fluid physics. It’s a culmination of 15 years of FYFD, rendered into narrative. I’m so excited to share it with you when it’s published in 2027.
As always, though, we’ll kick off the year with a look back at some of FYFD’s most popular posts of 2025. (You can find previous editions, too, for 2024, 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, and 2014.) Without further ado, here they are:
- Charged Drops Don’t Splash
- Strata of Starlings
- Espresso in Slow-Mo
- The Incredible Engineering of the Alhambra
- Uranus Emits More Than Thought1
- Kolmogorov Turbulence
- Bow Shock Instability
- How Particles Affect Melting Ice
- The Puquios System of Nazca
- Cooling Tower Demolition
- A Glimpse of the Solar Wind
- Bubbling Up
- A Sprite From Orbit
- Cornflower Roots Growing
- How Sunflowers Follow the Sun
What a great bunch of topics! I’m especially happy to see so many research and research-adjacent posts were popular. And a couple of history-related posts; I don’t write those too often, but I love them for showing just how wide-ranging fluid physics can be.
Interested in keeping up with FYFD in 2026? There are lots of ways to follow along so that you don’t miss a post.
And if you enjoy FYFD, please remember that it’s a reader-supported website. I don’t run ads, and it’s been years since my last sponsored post. You can help support the site by becoming a patron, buying some merch, or simply by sharing on social media. And if you find yourself struggling to remember to check the website, remember you can get FYFD in your inbox every two weeks with our newsletter. Happy New Year!
