It is suspected that certain blazars harbor binary black holes in them and maybe potential targets for future gravitational-wave searches. The first systematic study on the nature of gamma-ray flux variability on various types of blazars has been performed by researchers from the Indian Institute of Astrophysics (IIA), Bangalore. More about Blazars : There is a huge black hole at the core of most galaxies that can have masses of millions or even billions of suns accreting gas, dust, and stellar debris around it. As this material falls into the black hole, its gravitational energy is transformed into the light that forms active galactic nuclei (AGN). A minority of AGNs (~15%) emit charged particles called jets that fly at speeds similar to the speed of light. Blazars are the most bright and energetic objects in the known universe and in the 1990s they were discovered to be gamma-ray emitters. 1 Reply Share Share Share on Facebook Share on Twitter Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
