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 🌀🕳️

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 🤯🕳️

August Muller is a Fulbright research fellow in the “Astrophysical and Cosmological Relativity” department, working with Dr. Elisa Maggio.

She investigates how the upcoming @LISA gravitational-wave observatory can be used to test general relativity. LISA will see the first gravitational-wave signals from merging supermassive black holes, including the ringdown phase of the signal which is produced after the two black holes have already merged. Her research investigates how this ringdown signal may differ if the two black holes merge into an exotic object rather than a black hole in general relativity, in order to determine how well LISA will be able to distinguish these post-merger objects.

🚨 Gravitational-wave update to start the week

Over the weekend, three new potential gravitational-wave signals were detected. All three were detected using both @LIGO instruments and Virgo and, if real, come from black hole mergers. ⚫🌀⚫➡️⚫
