At the centre of the Milky Way galaxy resides a supermassive black hole four million times the mass of our sun called Sagittarius A* that some scientists have called a gentle giant because of its quiescence. But some day it could become a beast. Researchers on Tuesday said they have observed in real time a dramatic brightening at the heart of another galaxy, apparently caused by a supermassive black hole awakening from dormancy and beginning to gorge itself with nearby material.
“These nuclei are characterised by emitting large amounts of energy at a variety of wavelengths, from radio to gamma rays. They are considered one of the most luminous objects in the universe,” said astrophysicist Paula Sanchez Saez of the European Southern Observatory in Germany, lead author of the study published in the journal Astronomy and Astrophysics. “Studying active galactic nuclei is crucial to understanding galaxy evolution and the physics of supermassive black holes,” Sanchez said.
