🕳️ oddquark // Black Hole Watch — 2026-09-08
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 🤯🌌

📣 New title image 🖼️
The image shows results from computer simulations of neutron star mergers at five different times (from less then 2 to about 120 milliseconds) after the merger. Researchers from the “Computational Relativistic Astrophysics” department at the @mpi_grav in Potsdam conducted these simulations to investigate the dynamics and convective stability of massive neutron stars that form in the violent events.
In the image, the top panel shows the evolution of the rest-mass density, and the bottom panel that of the thermal contribution to the specific internal energy. The image is from Fig. 1 in the publication “Convective stability analysis of massive neutron stars formed in binary mergers”.

New catalog more than doubles the number of gravitational-wave detections made by LIGO, Virgo, and KAGRA observatories
The latest crop of space-time wobbles includes a variety of heavy, fast-spinning, and lopsided colliding black holes.

🎉 Happy belated birthday, GW230529!
Two years and a few days ago, the @LIGO Livingston gravitational-wave detector observed a remarkable gravitational-wave signal.
ℹ️ https://www.aei.mpg.de/1138125/mysterious-object-in-the-gap
Detected soon after the beginning of the fourth joint observing run of the LIGO-Virgo-KAGRA collaborations, the signal came from the merger of a compact object with 1.3 to 2.1 times the mass of our Sun with another compact object with 2.6 to 4.7 times the solar mass.
Astronomers believe that the lighter object is a neutron star and the heavier is a lightweight black hole.
How that lightweight black hole formed is unknown. Its masse falls into the “lower mass gap” between the heaviest neutron stars and the lightest black holes.
