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.
Looking for a dark matter needle in an X-ray stack
Can an unexplained signal found inside multiple galaxy clusters tell us something about dark matter? Find out about a tantalising indirect detection by X-ray astronomers.
Connecting galaxy properties to their star-formation histories
Star-forming galaxies form stars at different rates. Could this be the model that reveals the underlying physics?
Finding a supermassive black hole’s stellar-mass friends
After decades of searching, X-ray observations have revealed the existence of stellar-mass black holes close to a supermassive black hole.
Small, but Mighty! A galaxy robbed of its stars but contains a supermassive secret.
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.
How to Diagnose the Light from Early Galaxies
Understanding the physics of a certain emission line will allow astronomers to study galaxies that existed a long time ago far, far away.
