 XMM-Newton maps black hole surroundings

 Material falling into a black hole casts X-rays out into space – and now, for the first
 time, ESA’s XMM-Newton X-ray observatory has used the reverberating echoes of
 this radiation to map the dynamic behaviour and surroundings of a black hole itself.

Stormy cluster weather could unleash black hole power and explain lack of cosmic cooling

“Weather” in clusters of galaxies may explain a longstanding puzzle, according to a team of researchers at the University of Cambridge. The scientists used sophisticated simulations to show how powerful jets from supermassive black holes are disrupted by the motion of hot gas and galaxies, preventing gas from cooling, which could otherwise form stars. The team publish their work in the journal Monthly Notices of the Royal Astronomical Society.
