Ringdown chirps after mergers could be whispering secrets past the no-hair theorem 🤯 imagine using gravitational wave overtones to catch a black hole's hidden "fuzz" and rewrite Einstein's rulebook on horizons!

A STAR POWERED BY A BLACK HOLE?! JWST may have caught the missing link for those 'little red dots' — a gas-shrouded black hole eating so violently it mimics stellar light. Early universe physics is unhinged 🤯🕳️

Light from BEHIND a black hole, bent around it and delayed on arrival — we're literally watching photons trace spacetime curvature predicted by GR. The accretion disk's hidden far side, revealed by pure gravity. Absolutely unhinged 🤯🌌

Weekly Update from the Open Journal of Astrophysics – 06/06/2026
Another Saturday, 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 119 and the total so far published by OJAp up to 567.
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 Tuesday 2nd June, is “The impact of the formation channel on gravitational-wave-galaxy cross-correlations” by Kabir Chakravarti (Chennai Mathematical Institute, India) and Federico R Urban (CEICO-FZU, Czech Republic). This article, published in the folder Cosmology and Nongalactic Astrophysics, explores how uncertainties in binary formation affect the cross-correlation signal between gravitational wave events and galaxy catalogues, finding that time-delay distribution significantly impacts the signal.
The overlay for this paper is here
You can find the officially accepted version on arXiv here and the announcement on Fediverse here:
https://fediscience.org/@OJ_Astro/116679308847047911
The second paper for this week, also published on Tuesday 2nd June but in the folder High-Energy Astrophysical Phenomena, is “Transient X-ray Sources as Extremely Eccentric Mass-Transfer Binaries with Compact Companions” by Jonathan I Katz and Michael A Nowak (Washington University, St Louis, USA). This article suggests that X-ray transients, similar to tidal disruption events, are produced in eccentric stellar-compact object binaries, with their frequency gradually increasing over time.
The overlay for this one looks like this:
The official version of the paper can be found on arXiv here and the Fediverse announcement here:
https://fediscience.org/@OJ_Astro/116679395198117735
Next one up, the third paper of the week, also published on Tuesday 2nd June in the folder High-Energy Astrophysical Phenomena is “Resolving the (Debate About) Nozzle Shocks in Tidal Disruption Events” by Zachary L. Andalman & Eliot Quataert (Princeton U., USA), Eric R. Coughlin (Syracuse U. USA) and C. J. Nixon (U. Leeds, UK). This paper presents a model to understand the role of nozzle shocks in the circularization of stellar debris during a tidal disruption event when a star approaches a supermassive black hole (SMBH)
The overlay for this one is here:
The final, accepted version can be found on arXiv here and the Mastodon announcement is here:
https://fediscience.org/@OJ_Astro/116679426224933831
The fourth paper this week, published on Wednesday 3rd June in the folder Cosmology and Nongalactic Astrophysics, is “Validating Digital Twins of the Local Universe with the Thermal Sunyaev-Zel’dovich Signal” by Richard Stiskalek (University of Oxford, UK) and Harry Desmond (University of Portsmouth, UK). The thermal Sunyaev-Zel’dovich effect and constrained simulations are used to analyze the thermal pressure of ionized gas in galaxy clusters and produce a set of digital twins for cosmological study.
The overlay is here:
The officially accepted version can be found on arXiv here and here is the Mastodon announcement:
https://fediscience.org/@OJ_Astro/116684470440285496
The fifth and final paper this week, published on Thursday 4th June in the folder Cosmology and Nongalactic Astrophysics is “Photon (Non)Conservation in the Reduced Speed of Light Approximation and How to (Almost) Fix It” by Nickolay Y. Gnedin (University of Chicago, USA). The “Reduced Speed of Light” approximation in cosmological simulations can lead to photon non-conservation, and while some missing photons can be counted, adding them back is challenging.

And that concludes this week’s update. I’ll do another one next Saturday.

New header picture:
This month the volunteer distributed computing project @einsteinathome turns 20 years old.
The Einstein@Home volunteers have already discovered more than 90 new neutron stars, and we hope to discover many more in the future. Our long-term goal is the first direct detection of continuous gravitational waves.

Hello! #introductions #introduction
I am finishing grad student in #numericalrelativity (#generalrelativity, #astrodon) at #UArizona. I study #blackholes and #gravitationalwaves. I work a lot with #HPC and #Python. I am strong advocate for #OpenSource and #OpenScience.
My computer boots directly into #Emacs. I am involved with #vterm and other #elisp packages.
I am a massive fan of #nationalparks and enjoy #hiking and #cycling. I like to read about #history.
