Cold gas in cluster cores - past, present and future

Alastair Edge, Durham University

For many years one of the most contentious issues with cooling flows was the lack of any direct detection of the cold molecular gas that was predicted. In the past decade the observational evidence for a non-negligible mass of cold (T<50K) molecular gas existing in the cores of all cooling flows with short cooling times (<2Gyr) has become compelling. What role does this gas play in the AGN feedback process and the growth of the host BCG? I will review the current observations and look forward to future prospects with Herschel, ALMA and JWST.
