  3. GAS MOTIONS IN THE ICM Rebusco et al. 2006 Roediger et al. 2007 Simionescu et al. 2008 Markevitch&Vikhlinin 2007 Ascasibar&Markevitch 2006 Simionescu et al. in prep Einstein Fellows Symposium CfA, Oct. 28, 2009 Aurora Simionescu

  7. SLOSHING AND METAL TRANSPORT MFe=13.7e6 Msun MFe=4.5e6 Msun Simionescu et al. in prep Einstein Fellows Symposium CfA, Oct. 28, 2009 Aurora Simionescu

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

  9. 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

  10. CONCLUSIONS & ACKNOWLEDGEMENTS • 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.
