Scientists at the University of Cambridge have used
cutting-edge infrared surveys of the sky to discover a new population of
enormous, rapidly growing supermassive black holes in the early Universe. The
black holes were previously undetected because they sit cocooned within thick
layers of dust. The new study has shown however that they are emitting vast
amounts of radiation through violent interactions with their host galaxies. The
team publish their results in the journal Monthly Notices of the Royal Astronomical
Society.
