Indian astronomers have found an active galaxy in a very bright state that gives out ten times more X-ray emission than normal, equivalent to more than 10 trillion suns. 

Details

• This galaxy, located five billion light-years away, could help probe how particles behave under intense gravity and acceleration to the speed of light.
• It could help study the role of strong gravity and acceleration of matter in the formation, interaction and evolution of galaxies in the early universe.
• Every galaxy in the universe is believed to host a supermassive black hole at its centre. In some galaxies, the black hole is actively devouring a large amount of material and shooting a jet of plasma almost at the speed of light towards us. These are called blazars.
• An active galaxy with X-ray emission 10 times brighter than the normal was observed and located 5 billion light-years away.
• The study unleashed the function of a strong gravity in the formation, interaction and evolution of the early universe.
• The astronomers monitored a black hole named OJ 287 which displayed repeated optical brightness that confirmed the presence of a binary black hole.
