Scientific paper

Cold molecular gas has been found in several cooling flow clusters cores with single dish telescopes. We present here single dish observations of the NGC 1275 galaxy, at the center of the Perseus cluster. We have detected hints of large molecular gas filaments around the galaxy, with the multipixel camera HERA, through CO(2-1) emission lines. We have recently confirmed these detections with new 30m observations, showing that the cold gas follow the very peculiar H_α filamentary structure around the central galaxy and is certainly tracing, in some part, accreted gas toward the central object.
