New link found between mass of Supermassive black holes and their host galaxies

A team of astronomers has discovered a novel way to “weigh” supermassive black holes at the centres of galaxies by measuring the distances between the galaxies that contain them. Mysterious, massive dark objects lurk at the centre of nearly all galaxies and can be observed with high enough sensitivity. Astronomers believe these to be black … Read more

How to observe a ‘black hole symphony’ using gravitational wave astronomy

Shrouded in mystery since their discovery, the phenomenon of black holes continues to be one of the most mind-boggling enigmas in our universe. In recent years, many researchers have made strides in understanding black holes using observational astronomy and an emerging field known as gravitational wave astronomy, first hypothesized by Albert Einstein, which directly measures … Read more

Researchers apply the squeeze to better detect stellar-mass black holes

Stellar-mass black holes are formed by the gravitational collapse of a star. Their collisions are some of the most violent events in the universe, creating gravitational waves or ripples in space-time. These ripples are miniscule and detected using laser interferometers. Until now, many signals have been drowned out by so-called quantum noise on the laser … Read more

Massive filaments fuel the growth of galaxies and supermassive black holes

An international group of scientists led by the RIKEN Cluster for Pioneering Research have used observations from the Multi Unit Spectroscopic Explorer (MUSE) at the ESO Very Large Telescope (VLT) in Chile and the Suprime-Cam at the Subaru telescope to make detailed observations of the filaments of gas connecting galaxies in a large, distant proto-cluster … Read more
