Cold molecular gas in cooling flow clusters of galaxies.

SALOME P. and COMBES F.

Abstract (from CDS):

The results of a CO line survey in central cluster galaxies with cooling flows are presented. Cold molecular gas is detected with the IRAM 30m telescope, through CO(1-0) and CO(2-1) emission lines in 6-10 among 32 galaxies. The corresponding gas masses are between 3x108 and 4x1010M☉. These results are in agreement with recent CO detections by Edge et al. (2001MNRAS.328..762E). A strong correlation between the CO emission and the Hα luminosity is also confirmed. Cold gas exists in the center of cooling flow clusters and these detections may be interpreted as evidence of the long searched for very cold residual of the hot cooling gas.
