On the verge of revealing a singularity
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!
Distances in the Dark: Using Binary Black Holes to Study the Universe’s Expansion
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.
Putting Supermassive Black Holes on the Scale
A novel approach to estimate their mass may help reveal the relationship between supermassive black holes and the galaxies they inhabit.
The Circle of Life… of Black Holes
Today’s post presents SIMBA, a cosmological simulation that focuses on understanding the growth and evolution of black holes and their host galaxy.
Searching for Gravitational Waves From Binary Supermassive Black Holes Using Cosmic Lighthouses
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 Search for Black Hole Teenagers
The discovery of medium-sized black holes allow us to trace the history of the giant black holes in the center of galaxies.
