Galactic outflow

Astronomers studying the supermassive black hole at the centre of the galaxy IRAS F11119+3257 have found proof that the winds blowing from the black hole are sweeping away the host galaxy’s reservoir of raw star-building material.

This finding was made using ESA’s Herschel space observatory, together with the Suzaku X-ray astronomy satellite. Combining these data, the astronomers detected the winds being driven by the central black hole in X-rays, and their global effect, pushing the galactic gas away, at infrared wavelengths.
