Fermi maps plumes of active galaxy Centaurus A
Fermi’s Large Area Telescope resolved high-energy gamma rays from an extended region around the active galaxy Centaurus A. The emission corresponds to million-light-year-wide radio-emitting gas thrown out by the galaxy’s supersized black hole. NASA’s Fermi Gamma-Ray Space Telescope maps gamma rays, radiation that typically packs 100 billion times the energy of radio waves. Nevertheless, and to the surprise of many Read more »
Swift and XMM-Newton Satellites spots a Middleweight Black Hole
Good news for all who are interested in black holes! Astronomers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, find that an X-ray source in galaxy NGC 5408 that represents one of the best cases for a middleweight black hole to date. While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with Read more »
Astronomers Spots Intermediate-mass Black Hole
A team of astronomers have discovered a new category of black hole. Named as HLX-1, this new black hole is neither massive nor compact and lightweight. So, it is a medium-sized or intermediate black hole. Before it’s discovery, there was no solid evidence about the existence of intermediate mass black holes
