What happens when a black-hole gets indigestion? Galaxy hiccups!

Embargoed until: Publicly released:
Space boffins have spotted a galaxy with the hiccups - that is, a galaxy which has been producing strong, regular bursts of X-rays that can be detected from Earth. The international team, which includes Australian researchers, have observed X-ray bursts from a galaxy called GSN 069 that last for around one hour, repeating every 9 hours. The researchers suggest the eruptions of X-rays are coming from material flowing into the black hole located at the centre of the galaxy. As the material approaches the event horizon - or point of no return - at varying temperatures, it releases these X-ray bursts.
