Today’s post presents SIMBA, a cosmological simulation that focuses on understanding the growth and evolution of black holes and their host galaxy.
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.
Star-forming galaxies form stars at different rates. Could this be the model that reveals the underlying physics?
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.
Understanding the physics of a certain emission line will allow astronomers to study galaxies that existed a long time ago far, far away.
