3C196.1 is a massive elliptical galaxy, the brightest member of a cluster of galaxies about three billion light-years away that is notable for its strong X-ray and radio emission. The radiation is a characteristic signature of accretion processes around a supermassive black hole at the galaxy’s nucleus. Supporting this interpretation is the galaxy’s disturbed shape, which indicates the galaxy has undergone a recent merger, perhaps triggering such accretion onto the black hole and thus powering the emission.
