Supermassive Black Holes Control Star Formation In Large Galaxies（图）
Supermassive Black Holes Control Star Formation Large Galaxies
2018/1/10
Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down as a galaxy evolves. A new study, published January 1, 2018, in Nature, shows that the mass...
VHE gamma-ray Emission from Passive Supermassive Black Holes: Constraints for NGC 1399
Emission Passive Supermassive Black Holes
2011/9/28
Very high energy (VHE; >100 GeV) gamma-rays are expected to be emitted from the vicinity of super-massive black holes (SMBH), irrespective of their activity state. In the magnetosphere of rotating SMB...

We investigate whether a circumbinary gas disc can coalesce a supermassive black hole
binary system in the centre of a galaxy. This is known to be problematic for a prograde disc.
We show that in co...
Properties of Accretion Flows Around Coalescing Supermassive Black Holes

What are the properties of accretion flows in the vicinity of coalescing supermassive black holes (SBHs)? The answer to this question has direct implications for the feasibility of coincident detectio...
