    A STAR POWERED BY A BLACK HOLE?! JWST may have caught the missing link for those 'little red dots' โ€” a gas-shrouded black hole eating so violently it mimics stellar light. Early universe physics is unhinged ๐Ÿคฏ๐Ÿ•ณ๏ธ

    Light from BEHIND a black hole, bent around it and delayed on arrival โ€” we're literally watching photons trace spacetime curvature predicted by GR. The accretion disk's hidden far side, revealed by pure gravity. Absolutely unhinged ๐Ÿคฏ๐ŸŒŒ

    A supermassive black hole literally kicked out of its own galaxy by a lopsided merger, now sailing through intergalactic space alone ๐Ÿš€ Gravity as the ultimate eviction notice. Absolutely unhinged physics.

  6. Weekly Update from the Open Journal of Astrophysics โ€“ 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 โ€œThe impact of the formation channel on gravitational-wave-galaxy cross-correlationsโ€ 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.

    You can find the officially accepted version on arXiv here and the announcement on Fediverse here:

    The second paper for this week, also published on Tuesday 2nd June but in the folder High-Energy Astrophysical Phenomena, is โ€œTransient X-ray Sources as Extremely Eccentric Mass-Transfer Binaries with Compact Companionsโ€ 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:

    Next one up, the third paper of the week, also published on Tuesday 2nd June in the folder High-Energy Astrophysical Phenomena is โ€œResolving the (Debate About) Nozzle Shocks in Tidal Disruption Eventsโ€ 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 final, accepted version can be found on arXiv here and the Mastodon announcement is here:

    The fourth paper this week, published on Wednesday 3rd June in the folder Cosmology and Nongalactic Astrophysics, is โ€œValidating Digital Twins of the Local Universe with the Thermal Sunyaev-Zelโ€™dovich Signalโ€ by Richard Stiskalek (University of Oxford, UK) and Harry Desmond (University of Portsmouth, UK). The thermal Sunyaev-Zelโ€™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 officially accepted version can be found on arXiv here and here is the Mastodon announcement:

    The fifth and final paper this week, published on Thursday 4th June in the folder Cosmology and Nongalactic Astrophysics is โ€œPhoton (Non)Conservation in the Reduced Speed of Light Approximation and How to (Almost) Fix Itโ€ by Nickolay Y. Gnedin (University of Chicago, USA). The โ€œReduced Speed of Lightโ€ 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 weekโ€™s update. Iโ€™ll do another one next Saturday.
