I've worked quite a bit on this object. The Perseus cluster is one of the most interesting galaxy clusters in the sky and is the X-ray brightest (and so well studied). There's star formation, bubbles of relativistic plasma bubbles generated by the central black hole, presumably heating the surrounding gas and preventing catastrophic cooling, sound waves generated by the inflation of the bubbles, a giant nebula producing emission lines. You could give several talks about this object... Some nice pics here of the central galaxy, NGC1275: http://www-xray.ast.cam.ac.uk/papers/ngc1275/ We'll have…
