The role of cooling flows in the star formation history of central cluster galaxies

Using a recent determination of the X-ray luminosity function of galaxy clusters, accurate mass deposition rates and L-X in cooling how clusters from the literature, and reliable constraints on the star fomation episodes in cooling flows obtained by our group, we quantify the relevance of such star formation in comparison with the SFR in the local universe. We conclude that the SFR density in CF is less than or similar to 0.1% the total local reference(1).
