Indian researchers discover 3 black holes from 3 galaxies merging together to form a triple active galactic nucleus
Supermassive black holes are difficult to detect because they do not emit any light, but they can reveal their presence by interacting with their surroundings.

Chinese space telescope to observe 'big eaters'
When a black hole swallows too much, the excess matter is converted into two jet-flows perpendicular to the accretion disk of the black hole, which is like a glutton with a bloated belly belching.
