A novel approach to estimate their mass may help reveal the relationship between supermassive black holes and the galaxies they inhabit.
Today’s post presents SIMBA, a cosmological simulation that focuses on understanding the growth and evolution of black holes and their host galaxy.
The NANOGrav collaboration is using dense, rotating neutron stars that act as lighthouses in the cosmos to search for gravitational waves at the nanohertz scale that are emitted by pairs of supermassive black hole binaries!
The discovery of medium-sized black holes allow us to trace the history of the giant black holes in the center of galaxies.
After decades of searching, X-ray observations have revealed the existence of stellar-mass black holes close to a supermassive black hole.
Today’s post looks at the investigation of a very small galaxy hosting a black hole that’s 15% of its total mass. This paper investigates whether this was once a much bigger galaxy, but has been robbed of its stars by a close call with another nearby galaxy.
