Team Led By University Of Leicester Sets New Record For Cosmic X-Ray Sightings
Scientists led by the University of Leicester have set a new record for cosmic X-ray sources ever sighted – creating an unprecedented cosmic X-ray catalogue that will provide a valuable resource allowing astronomers to explore the extreme Universe.
The XMM-Newton Survey Science Centre, led by a team from the University of Leicester’s Department of Physics and Astronomy, used the University’s ‘ALICE’ supercomputer to help them produce a new X-ray catalogue, dubbed “3XMM”.
This new catalogue contains over half a million X-ray source detections, representing a 50% increase over previous catalogues and is the largest catalogue of X-ray sources ever produced. This vast inventory is also home to some of the rarest and most extreme phenomena in the Universe, such as tidal disruption events – when a black hole swallows another star, producing prodigious outbursts of X-ray emission.
