Quasars are luminous objects with supermassive black holes at their centres, visible over vast cosmic distances. Infalling matter increases the black hole mass and is also responsible for a quasar’s brightness. Now, using the W.M. Keck observatory in Hawaii, astronomers led by Christina Eilers have discovered extremely young quasars with […]

Discovery in the early universe poses black hole growth puzzle




Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a surprising connection between a supermassive black hole and the galaxy where it resides. Powerful radio jets from the black hole – which normally suppress star formation – are stimulating the production of cold gas in the galaxy’s extended halo […]
