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...
