How can we measure how fast an object is spinning when we can’t even see it? Read on to hear about measurements of a black hole pirouetting at breakneck speeds!
Astronomers can now measure the expansion rate of the universe using gravitational wave signals from binary black hole mergers, a new step forward in the era of precision cosmology.
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.
