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.

Understanding mysterious magnetars 🧲 and radio bursts 🌟 with gravitational waves

A flash of radio waves lasting a few thousandths of a second, as bright as millions or billions of stars, and it’s all over: even almost 20 years after their discovery, fast radio bursts remain one of the most mysterious phenomena in our Universe. Scientists believe that neutron stars – very small and extremely dense stellar remnants with huge magnetic fields – emit these bursts.

An international team has now used gravitational waves to study a nearby neutron star that has emitted several radio bursts. The researchers analyzed data from the German-British GEO600 detector to learn more about the origin of these events. Their results contribute to a better understanding of these extreme events and their theoretical description.

Gravitational wave researchers cast new light on Antikythera mechanism mystery

Techniques developed to analyse the ripples in spacetime detected by one of the 21st century’s most sensitive pieces of scientific equipment have helped cast new light on the function of the oldest known analogue computer.
