An entirely new way to probe how active black holes behave when they eat has been discovered by an international team of astronomers.
A sample of active black holes at the centre of 136 galaxies were found to shine in microwave and X-ray light in the same way, no matter their appetite for the surrounding galactic matter like clouds of gas and dust.
Led by scientists at Cardiff University, the team says the process is not something predicted by our current understanding of how black holes eat.
Currently understood to be intrinsically different depending on their appetites, active black holes are characterised by the layout of their cores and the way they draw in galactic matter.
