VLA Reveals New Object Near Supermassive Black Hole in Famous Galaxy
VLA New Object Near Supermassive Black Hole Galaxy
2017/7/20
Pointing the National Science Foundation’s Very Large Array (VLA) at a famous galaxy for the first time in two decades, a team of astronomers got a big surprise, finding that a bright new object had a...

We consider a scenario where supermassive black holes form through direct accumulation of gas at the centre of proto-galaxies. In the first stage, the accumulated gas forms a super-massive star whose ...
Ever since supermassive black holes were found to lurk at the heart of most large galaxies, astronomers have wondered what came first: the galaxies or the black holes themselves? Now astronomers in th...
Lurking at the centre of nearly every galaxy and gobbling up stars in their vicinity, supermassive black holes are a truly menacing feature of the universe. Now, an international team of astronomers c...
