Herschel:Black holes and star formation: a Herschel perspective

The effects of supermassive black holes on their host galaxies pose a tricky puzzle: are black holes able to influence, and possibly even suppress, star-formation activity on galactic scales? Astronomers have been searching for a signature of such a feedback effect, and have been spurred on recently by the large surveys of distant galaxies compiled with ESA&aposs Herschel Space Observatory. A variety of results has emerged from the first joint analyses of these data and other observations, performed either in X-rays or in radio waves, but the only certainty so far is that it remains a vexed question.
