A Shocking Model of FRBs
Multiple models have been proposed to explain the intriguing properties of FRBs, but this new model provides one of the most detailed scenarios yet, consistent with properties of current observed FRBs.
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.
