There are stellar-mass and supermassive black holes. But very little evidence of anything in between. Where are all the intermediate-mass black holes that should be the building blocks of the biggest ones?
How do we explain the giant black holes appearing in the young universe? Is it possible to directly collapse a black hole, skipping the formation of stars? What does ultraviolet radiation have to do with this?
Join us on today’s podcast at #365DaysOfAstro as NOIRLab discuss about the discovery of LID-568, a black hole that is feeding at 40 times the theoretical limit.
How do black holes get close enough to merge? What causes them to emit gravitational waves, and where do the waves come from?
Join us today as we deep dive into Hera and Clippers journey to look at other worlds, also news from black holes.
Just how useful are humans in space? What is the death zone radius of a black hole merger? More about staying alive with @CheapAstro at #365DaysOfAstro
The Event Horizon Telescope (EHT) Collaboration has unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy! More about it with @cosmicsavannah at #365DaysOfAstro
Using archival data from the Gemini North telescope, a team of astronomers have measured the heaviest pair of supermassive black holes ever found.
We thought stellar mass black holes came from stars and that there might have been tiny primordial black holes that evaporated away, but that was it. Closed case. Black holes formed with all the normal structures we experience today. Except that now, JWST’s observations require us to find a way to accelerate the formation of those structures, and one way to do that is to seed the universe with black holes.
