How did supermassive black holes in the early universe get so massive? Today’s bite uses simulations to investigate whether galaxy mergers can help beef up black holes.
GW231123 defies our best models of stellar collapse, hosting two black holes that shouldn’t exist. A new paper proposes a radical solution: these monsters may have been born in the early universe as primordial black holes, quietly feeding for billions of years until they became the record-breakers we detected today.
Black hole accretion must be SANE or MAD, right? Maybe not…read to learn more!
Little Red Dots may just be the Shaqs of the galaxy world: extreme and impressive, but not a new kind of object.
Tidal disruption events can happen when stars are torn apart by a supermassive black hole at the centre of a galaxy. Guest author, Mary Ogborn, explains how tidal disruption events can help us see when supermassive black holes wander away from their galaxy’s centre.
Another day, another interesting LIGO-Virgo-KAGRA detection! Find out why the extreme parameters of GW231123 create problems for gravitational wave modelers and may have some new information about black hole formation!
