Weekly Update from the Open Journal of Astrophysics – 25/04/2026

So here we are again, on a Saturday morning, with another 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 87 and the total so far published by OJAp up to 535.

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 this week is “Bayesian Cosmic Void Finding with Graph Flows” by Leander Thiele (U. Tokyo, Japan). This was published on Monday 20th April in the folder Cosmology and Nongalactic Astrophysics. The paper presents a method using a deep graph neural network to identify cosmic voids in sparse galaxy surveys, improving upon traditional deterministic algorithms by considering the problem’s probabilistic nature. The overlay is here:

The second paper for this week, published on Wednesday 22nd April in the folder Astrophysics of Galaxies, is “Sifting for a Stream: The Morphology of the 300S Stellar Stream” by Benjamin Cohen (U. Chicago, USA) and 20 others distributed around the world. This study analyzes the morphology of the $300S$ stellar stream, revealing three density peaks, a possible gap, and a kink, suggesting significant influence from the Large Magellanic Cloud on its structure.

Next one up, the third paper of the week, is “IRMaGiC: Extending Luminous Red Galaxy Selection into the Infrared with Joint Rubin Observatory’s Large Survey of Space Time and Roman’s High Latitude Imaging Survey” by Zhiyuan Guo & Chris. W. Walter (Duke U., USA) and Eli S. Rykoff (Stanford U., USA) on behalf of the LSST Dark Energy Science Collaboration. This was published on Wednesday April 22nd in the folder Cosmology and Nongalactic Astrophysics. The paper introduces IRMaGiC, an algorithm that improves the selection and redshift estimation of Luminous Red Galaxies (LRGs) by incorporating infrared data, enhancing future cosmological surveys.

The fourth paper this week, published on Thursday April 23rd, is “The Diagnostic Temperature Discrepancy as Evidence for Non-Maxwellian Coronal Electrons” by Victor Edmonds (Final Stop Consulting, USA). This paper, in the folder Solar and Stellar Astrophysics, presents two methods of measuring electron temperature in the quiet solar corona yielding different results, suggesting non-Maxwellian electron velocity distributions may be responsible for the discrepancy.

The fifth and final paper for this week was published on Friday 24th April in the folder Astrophysics of Galaxies. The title is “Galaxy evolution in the post-merger regime. IV – The long-term effect of mergers on galactic stellar mass growth and distribution” by Sara L. Ellison (U. Victoria, Canada) and Leonardo Ferreira (Universidade Federal do Rio Grande, Brazil). This study uses a large sample of post-merger galaxies to demonstrate that galaxy mergers trigger significant and extended stellar mass growth in their central regions, independent of stellar population modelling.

Weekly Update from the Open Journal of Astrophysics – 18/04/2026

It is Saturday morning, and therefore time for yet another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further six papers, bringing the number in Volume 9 (2026) to 82 and the total so far published by OJAp up to 530.

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 this week is “Beyond Spherical geometry: Unraveling complex features of objects orbiting around stars from its transit light curve using deep learning” by Ushasi Bhowmick & Shivam Kumaran (Indian Space Research Institute, Ahmedabad, India). This study uses deep neural networks to predict the shape of objects orbiting stars based on their transit light curves, demonstrating the potential to extract geometric information from these systems. It was published on Monday 13th April in the folder Earth and Planetary Astrophysics and the overlay can be seen here:

https://fediscience.org/@OJ_Astro/116395992732332356

The second paper for this week, also published on Monday 13th April Apil in the folder but in the folder Astrophysics of Galaxies, is “statmorph-lsst: Quantifying and correcting morphological biases in galaxy surveys” by Elizaveta Sazonova (U. Waterloo, Canada) and an international cast of 18 others. This paper presents an investigation of potential biases in quantitative morphology metrics used in galaxy evolution studies, proposing two new measurements to resolve biases, and provides a related Python package (statmorph-lsst), which can be found here on github.

https://fediscience.org/@OJ_Astro/116396069424189312

Next one up, the third paper of the week, one of four published on Friday 17th April, is “Disentangling the galactic and intergalactic components in 313 observed Lyman-alpha line profiles between redshift 0 and 5” by Siddhartha Gurung-López (Universitat de València, Spain) and 7 others based in Spain and Germany. Published in the folder Astrophysics of Galaxies, this paper uses the zELDA package to analyze Lyman-alpha photons from star-forming galaxies, revealing IGM effects dominate Lyman-alpha observability at high redshifts, while galactic outflows become more important at lower z.

The final, accepted version can be found on arXiv here and the Mastodon announcement is here:

https://fediscience.org/@OJ_Astro/116418831864134501

The fourth paper this week, also published on Friday 17th April is “Using Symbolic Regression to Emulate the Radial Fourier Transform of the Sérsic Profile for Fast, Accurate and Differentiable Galaxy Profile Fitting” by Tim B. Miller (Northwestern University, USA) and Imad Pasha (Yale University, USA). This one is published in the folder Instrumentation and Methods for Astrophysics: it develops an emulator for galaxy profile fitting in Fourier space, improving speed by 2.5 times with minimal accuracy loss, aiding in managing increasing data flow.

The finally accepted version of this paper can be found here and the Mastodon announcement follows:

https://fediscience.org/@OJ_Astro/116418855010158656

The fifth paper for this week is “The THESAN project: Lyman-alpha emitters as probes of ionized bubble sizes” by Meredith Neyer (MIT, USA) and 6 others based in the USA, Colombia, Canada, Japan and UK. The study uses THESAN simulations to explore how Lyman-alpha emitters (LAEs) trace ionized bubble sizes during the Epoch of Reionization, providing a framework for interpreting LAE surveys. This was published on Friday 17th April in the folder Astrophysics of Galaxies.

https://fediscience.org/@OJ_Astro/116418887225003954

The sixth and final paper for this week is “Closed-Form Statistical Relations Between Projected Separation, Semimajor Axis, Companion Mass, and Host Acceleration” by Timothy D Brandt (Space Telescope Science Institute, USA). This was published on Friday 17th April in the folder Solar and Stellar Astrophysics. In this paper the author derives statistical relationships between radial velocity, a companion’s mass, and projected separation, useful for calculations requiring derivatives. The results are verified with empirical comparisons to existing literature.

Rubin Observatory spustil alertový systém
📡 Historický milník: Observatoř Vera C. Rubin v Chile spustila 24. 2. real-time alertový systém. První noc — 800 000 alertů: supernovy, proměnné hvězdy, aktivní jádra galaxií, asteroidy.
Cíl: až 7 milionů alertů/noc. Změny hlášeny do 2 minut od snímku. Největší digitální kamera (3 200 Mpx) začíná plnit účel. Letos startuje desetiletý průzkum LSST.

#LSST performs very well for large impactors ☄️, discovering about 79.7% of objects larger than 140 m before impact. Only 50.3% of 50–140 m impactors, 26.8% of 20–50 m impactors, and 10.5% of 10–20 m impactors are discovered 🔭 at all. About 60% of large impactors fail to reach a one-year warning threshold. Upper mid-size objects are usually discovered only a few months before impact 💥 https://www.newplanetarium.com/journal/2026-01-29

#RubinObservatory #AsteroidThreat

"Rubin Observatory sends out thousands of data alerts" by GeekWire / @alanboyle - The first night of astronomical alerts from the high-resolution sky survey of #RubinObservatory #LSST was a batch of 800,000 possible new object detections. This is apparently the new normal. Astronomers have a flood of new data to process every day. https://www.geekwire.com/2026/rubin-observatory-data-alert/ #space #astronomy #tech

Rubin Observatory spots an #asteroid that spins fast enough to set a record
The asteroid, known as #2025MN45, is nearly half a mile (710 meters) in diameter and makes a full rotation every 1.88 minutes, based on an analysis of data from the #VeraCRubinObservatory in #Chile.
2025 MN45 is one of more than 2,100 solar system objects detected during the observatory’s commissioning phase. Over time, the #LSST Camera tracked variations in the light reflected by those objects.

"Software suggests Rubin Observatory will discover millions of solar system objects" by GeekWire / @alanboyle - Getting a grasp on what effect the high-resolution sky survey of #RubinObservatory #LSST will have: using previous rates of discovery of asteroids to estimate what we don't yet know, multi-university Sorcha simulation forecasts LSST may discover half of all then-known asteroids within a year. And its majority share will continue to grow. https://www.geekwire.com/2025/sorcha-software-rubin-observatory-millions/ #space #astronomy
