Weekly Update from the Open Journal of Astrophysics – 23/05/2026

It’s Saturday once again, so time for 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 110 and the total so far published by OJAp up to 558.

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 18th May in the folder Instrumentation and Methods for Astrophysics is “Edges In Coadded Images” by Erin Sheldon (Brookhaven National Laboratory, USA). This paper describes a study exploring how image discontinuities and noise impact weak gravitational lensing measurements, finding no significant biases under typical conditions. Biases occur only in extreme cases, but can be mitigated.

The second paper for this week, also published on Monday 18th May but in the folder Cosmology and Nongalactic Astrophysics, is “Joint cosmological fits to DESI-DR1 full-shape clustering and weak gravitational lensing in configuration space” by A. Semenaite (Swinburne Institute of Technology, Australia) and 72 other authors from all round the world. This paper presents a cosmological analysis of correlations between the DESI-DR1 Bright Galaxy Survey and Luminous Red Galaxy samples and overlapping shear measurements from various weak lensing surveys.

Next one up, the third paper of the week, and the third published on Monday 18th May, also published on Tuesday 12th May, and in the folder Cosmology and Nongalactic Astrophysics is “Probing Dark Energy Microphysics with kSZ Tomography” by Julius Adolff, Selim Hotinli and Neal Dalal (all of the Perimeter Institute, Canada). This paper explores how kinetic Sunyaev-Zel’dovich tomography and galaxy clustering can enhance our understanding of dark energy and its effects, potentially revealing its microphysical properties in future surveys.

The fourth paper this week, published on Wednesday May 20th “A Census of Variable Radio Sources at 3 GHz” by Yjan A. Gordon, Peter S. Ferguson, Michael N. Martinez and Eric J. Hooper (all of the University of Wisconsin, USA). This article, published in the folder Astrophysics of Galaxies, uses data from the Very Large Array Sky Survey to analyze variability in the radio sky, finding most changes consistent with blazars and quasars.

The fifth article of this week was published on Friday 22nd May in the folder Instrumentation and Methods for Astrophysics. The title is “Uncovering the Next Galactic Supernova with the Vera C. Rubin Observatory” by John Banovetz (Lawrence Berkeley Lab., USA), Claire-Alice Hebert & Peter B. Denton (Brookhaven National Lab., USA), Dan Scolnic (Duke University, USA), Anze Slosar (Brookhaven) and Chris Walter (Duke). The paper presents a study simulating how effectively the Vera C. Rubin Observatory can localize supernovae using neutrino triggers, finding a 57-97% success rate based on stellar mass density predictions.

Last, but by no means least, this week we have “Pulsar timing solutions for 17 pulsars at 150 MHz from the Irish LOFAR station” by David J. McKenna (ASTRON, The Netherlands), Evan F. Keane (Trinity College Dublin, Ireland), Peter T. Gallagher (DIAS, Ireland) and Joe McCauley (Trinity). This was published on Friday 22nd May in the folder High-Energy Astrophysical Phenomena. It presents a demonstration of the use of international Low Frequency Array (LOFAR) stations in tracking and characterizing pulsars, providing new insights into these neutron stars’ emission properties.

🐭🎶 New paper by Isko et al, who study #Alston’s singing mouse, a rodent with loud, stereotyped songs.

Using bulk tracing, serial #2P #tomography, & #MAPseq of >76,000 barcoded neurons, they find expanded projections from #orofacial #MotorCortex to #auditory #cortex & #PAG. This suggests that singing / #Vocalization may emerge not from entirely new circuits, but from selective strengthening of existing motor, auditory & vocal-control pathways.

"High-throughput phenomics of global ant biodiversity", Katzke et al. 2026
https://www.nature.com/articles/s41592-026-03005-0

"within the open science initiative ‘Antscan’, we applied high-throughput synchrotron X-ray microtomography to capture phenotypes across a diverse and ecologically dominant insect group: ants. At https://www.antscan.info, we provide 2,193 whole-body three-dimensional ant datasets from 212 genera and 792 species to broadly cover the ant phylogeny with a global scope, also pairing phenomic data with genome sequencing projects."

[theories abound]
"... KEY POINTS
• Employing time dependent global mantle convection models since the Cretaceous. [the authors] simulate the origin of the enigmatic Indian Ocean geoid low
• Plumes forming along the edges of the African Large Low Shear Velocity province (LLSVP) control the regional geoid in the Indian Ocean
• These plumes, in turn are generated by lower mantle Tethyan slabs that perturb the African LLSVP…”

Tim Salditt (http://twitter.com/SaldittLab, substituting Jasper Frohn): #Multiscale #Xray Phase Contrast #Tomography at #GINIX/P10: Concepts, Implementation and Applications

- fantastic collaboration with the P10 team
- directly comparing #STED to #Minflux; old #confocal? not worth mentioning 😂
- overview tomo, then zoom-in
- tumorous human pancreatic tissue #biopsy: quantify the #tumor type
- from electron density to metrics, quantify fibres etc.
- #hippocampus patho punch, #Alzheimer sample

is happy to have spent *so much* time on automated extraction of single fish from 20 combined tomographic scans (20 x 6 fish) a while ago. Because re-doing this on a fresh TB batch of 8 scans (48 fish) of nearly equal fish is done in half a morning.

is happy to hear that https://doi.org/10.1101/2024.11.10.622888 “has been judged scientifically suitable for publication" in PLOS One after a round of peer review. Once "it meets all outstanding technical requirements" it will be published online. For the moment you all have to read the bioRxiv version. And can nonetheless already look into the full dataset yourself, for example at https://webknossos.org/links/U8wuIdhmfzWMr7rm

New paper, just published in Physical Review X Energy, on the muography of the G3 nuclear reactor

by Baptiste Lefevre and co-authors
https://doi.org/10.1103/PRXEnergy.4.013002

The visualization software I developed for #Cosmology contributed in the mapping of the inner, inaccessible structure of the reactor.

Gleich beginnt die nächste Postersitzung beim #DESY Nutzerinnentreffen #UM25 – mein heutiger Beitrag:

"#FPGA Based Live-Reco for #Tomography: Preparing for 4th Generation Data Rates"

Mit dem Upgrade zum #PetraIV #Synchrotron erwarten wir eine rund hundertfach höhere Datenrate, speziell in der Parallelstrahl-#Tomografie an der #GINIX könnten es ca. 3 Petabyte täglich werden. Hier studieren wir eine Live-Rekonstruktion des Datenstroms mittels programmiererbarer Hardware.
