Just accepted in !

How do we spot merging supermassive black holes? Our new 3D GRMHD simulations reveal a "smoking gun" signal: a sharp jump in light and jet power at the moment of merger, driven by strong shocks.

A crucial step for multimessenger astronomy!

I am excited to share our new paper, "The merger of spinning, accreting supermassive black hole binaries"! We found that when these black holes collide, their "light show" actually dims right before the merger, then suddenly gets much brighter. This unique signature could help us find black hole mergers in the future, even without gravitational wave signals.
