IRAS 13224-3809

Galaxy containing well-studied supermassive black hole

IRAS 13224-3809 is a highly active and fluctuating Seyfert 1 galaxy in the constellation Centaurus[2] about 1 billion light-years from Earth.[3][5][6] The galaxy is notable due to its centrally-located supermassive black hole that is closely studied by astronomers using x-ray astronomy, particularly X-ray reverberation echo mapping techniques, in an effort to better understand the inner workings, including mass and spin, of black holes.[3][5]
