Close Galactic Encounter Leaves Nearly Naked Supermassive Black Hole
2016/11/29
Astronomers using the super-sharp radio vision of the National Science Foundation's Very Long Baseline Array (VLBA) have found the shredded remains of a galaxy that passed through a larger galaxy, lea...
THE MURMUR OF THE HIDDEN MONSTER: CHANDRA'S DECADAL VIEW OF THE SUPERMASSIVE BLACK HOLE IN M31
X-ray source flaring emission
2014/12/20
The Andromeda galaxy (M31) hosts a central supermassive black hole (SMBH), known as M31*, which is remarkable for its mass (~108 M ) and extreme radiative quiescence. Over the past decade, the Chandra...
