Cold molecular gas in cooling flow clusters of galaxies
190 citations recorded by the source corpus.
The results of a CO line survey in central cluster galaxies with cooling flows are presented. Cold molecular gas is detected with the IRAM 30 m telescope, through CO(1–0) and CO(2–1) emission lines in 6–10 among 32 galaxies. The corresponding gas masses are between $3\times10^{8}$ and $4\times10^{10}$ $M_\odot$. These results are in agreement with recent CO detections by [CITE]. A strong correlation between the CO emission and the H α 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.

- On the Nature of Feedback Heating in Cooling Flow Clusters (2004, background): “(i) In the hot feedback models the optical filaments observed in many CF-clusters (Heckman et al. 1989), and the cooler molecular gas detected via CO observations (Edge 2001; also Edge & Frayer 2003; Salomé & Combes 2003; Salomé & Combes 2004) come from stripping gas from cluster galaxies.”
- Cold molecular gas in the Perseus cluster core - Association with X-ray cavity, Halpha filaments and cooling flow - (2006, methodology): “A strong correlation of Hα with CO, at ∼10-100 K (Edge 2001; Salomé & Combes 2003) has been discovered, which is reinforced by a clear association, both in morphology and dynamics, revealed in the IRAM PdBI CO(1-0) and CO(2-1) maps of Abell 1795.”
- Radiative efficiency, variability and Bondi accretion on to massive black holes: the transition from radio AGN to quasars in brightest cluster galaxies (2012, background): “Edge 2001; Salomé & Combes 2003) we suggest that cold gas fuelling is a likely source of accretion power in these objects.”
