Looking for Supermassive Black Holes
The amplitude of the gravitational wave background is too high for the number of supermassive black holes that we’ve observed! Find out how we can resolve this issue in today’s bite
Weight Gain: Growing Little Black Holes in the Early Universe
Astronomers are actively researching how massive black holes arise in the early universe. Is it possible for small black holes to grow fast enough to become one of these supermassive black holes? Today’s authors think there’s a chance!
Does dark matter play a role in the origin story of supermassive black holes?
Find out in today’s bite if dark matter has any role in the formation of supermassive black holes!
“Barbie” Breaks Another Record: ZTF20abrbeie is the most energetic optical transient observed so far
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!
Don’t Be So Cold – Self-Interacting Dark Matter as a Solution to the ‘Final Parsec Problem’
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.
Can you hear the (ultralow-frequency gravitational wave) music?
Gravitational waves hum in various frequencies. Can we hear the ultralow frequency ones ? Find out in today’s bite.
