XMM Observations of the X-ray Halo of M87 Böhringer et al. 2001, 2002 Matsushita et al. 2002a, b Finoguenov et al Sakelliou et al. 2002

O & Si Abundance Profiles in M87 The O profile is almost flat (consistent with a flat profile within %) The O/Si ratio increases from about 0.4 to 0.7 (from r = 2 – 50 kpc) - (using MEKAL models) Si 1-temp O Si Matsushita, Finoguenov, Böhringer temp

X-IGM vs starformation Alexis Finoguenov Conclusion from the Abundance Pattern Most of the Fe in the center comes from SN Ia -- This Fe can be produced by SN Ia from M87 within the last Gyr (with a Cappelaro rate of SN in early type galaxies) The abundance pattern clearly favor slow deflagration/detonation models – with incomplete burning of the  -elements Second order effect: there may be a variation in the types of SN Ia (later SN Ia show on average more  -elements -- slower explosions) The total Fe contribution by SN II falls about a factor of short in explaining the wide-spread Fe abundance with classical IMF models  we can test chemical evolution parameters  we can test SN-nucleosynthesis models

X-IGM vs starformation Alexis Finoguenov Summary Fossil records study consistently require both strong feedback and top heavy IMF at high-z Protoclusters are sights of missing metals at high-z, which are at high temperatures Feedback energy, released at high-z, appears to cool down by now. Observations of groups support AGNs as a dominant source of feedback. Current deep surveys are capable of finding and study groups at high-z.
