Supermassive black holes continue to surprise: a recent extragalactic explosion proved to be the most luminous optical transient we have observed so far. Read about “Scary Barbie” and a potential explanation for her origin!
In today’s bite, we look at a paper that investigates if self-interacting dark matter can accelerate the inspiral of supermassive black holes binaries, and if we can detect this with gravitational waves.
Gravitational waves hum in various frequencies. Can we hear the ultralow frequency ones ? Find out in today’s bite.
Black holes are hungry, loud eaters! Find out what they sound like as they burp the remains of a star!
Does dark matter density spike around a supermassive black hole ? New evidence might seem to suggest so. Check out more in today’s bite!
The wonderful population of massive black holes gardens seen in today’s galaxies were once seeds in the early universe. What were the seeds like ? Find out in today’s bite.
