Cosmic Collision Fires Up Quasar SDSS J0123+00

Using two of the world’s largest telescopes, the Very Large Telescope (VLT) in Chile and the Gran Telescopio Canarias (GTC) on La Palma in the Canary Islands, an international team of astronomers have found evidence of a collision between galaxies driving intense activity in a highly luminous quasar, SDSS J0123+00.  Several types of galaxies, known as active galaxies, emit enormous amounts of energy from their central region or nucleus, with the most luminous objects known as quasars. Many scientists argue that quasars contain a central black hole, with a mass of at least several million Suns. read more
