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.

The dwarf galaxies under observation were still accumulating gas which should re-start star formation in a red, dead galaxy but wasn't.

The study published in the journal Nature Astronomy sheds light on a class of black holes having a mass upwards of one million times the mass of the Sun.
NASA's SOFIA detects cool dust around active black holes!
SOFIA flies above 99 percent of the Earth's water vapour, enabling the research group to characterise the properties of the torus-shaped dust structures at far-infrared wavelengths.

Monster black holes, it seems, also sometimes lurk behind gas and dust, hiding from the gaze of most telescopes.
Jan 08, 2017, 23:35 PM ISTWhy some galaxies have become barren
Over the last few billion years, a mysterious kind of galactic warming has caused many galaxies to change from a lively place where new stars formed every now and then to a quiet place devoid of fresh young stars.
