  1. "I put my money on LISA" to finally prove the existence of #BlackHoles via #GravitationalWaves: thus Reinhard Genzel concluded his #ag2026garching talk - and then showed the hilarious short youtu.be/8WQXGQYi5kg

    S301 whipping past Sgr A* at 8% lightspeed could let us actually measure OUR black hole's spin via frame-dragging on its orbit. Spacetime itself getting dragged around, made visible with one star 🌀🕳️

  13. 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.

  19. Scientists find evidence of a gravitational wave ‘hum’
    Astrophysicists have found the best evidence yet for a low-frequency “hum” of gravitational waves rippling through the cosmos, based on 15 years’ worth of ultra-precise measurements checking the timing of radio pulses from distant stars.

  20. Well, since we are bracing for the impact of an imminent major announcement on pulsars and, maybe, some gravitational wave background, why not enjoy this 2004 special Science Magazine issue on pulsars!

  21. Will a project "using #pulsars to search for low-frequency #GravitationalWaves" report a significant detection next week? Says nitter.net/NANOGrav/status/167: "Mark your calendars and get ready for a major announcement from the #NANOGrav collaboration on June 29th!" And - coincidence? - a big primer about Pulsar Timing Arrays such as NANOGrav appeared only days ago at spaceaustralia.com/feature/hum
