METAL ENRICHMENT OF ICM cD initial Leccardi et al Einstein Fellows Symposium CfA, Oct. 28, 2009 Aurora Simionescu

METAL ENRICHMENT OF ICM Mg, O: core collapse products Fe: SN Ia product Enrichment by BCG at late times: only SN Ia -> not the only contribution to the peak Enrichment in protocluster phase much more peaked than previously thought Einstein Fellows Symposium CfA, Oct. 28, 2009 Aurora Simionescu

CONCLUSIONS & ACKNOWLEDGEMENTS Einstein Fellows Symposium CfA, Oct. 28, 2009 Aurora Simionescu Cold fronts are very important means of broadening the metal abundance profile in the ICM The enrichment patterns are similar close to and far away from the central cluster galaxy -> most metals produced at early times THANKS TO N.
