The X-ray halo of NGC 4634

The metal content of the interstellar and intergalactic medium is one of themost sensitive and significant imprints of the star formation history overcosmological timescales. In current models feedback mechanisms are crucial toexplain the observed properties of galaxies. In a survey of Xray properties ofedgeon disk galaxies we have identified NGC 4634 as a target best suited tostudy the properties of an outflow governed by the distributed star formation.We propose to obtain Xray spectra with significantly higher S/N to betterconstrain the metal content of the gaseous halo. We want to extract spatiallyresolved spectra which will allow us to discuss the enrichment and mixingprocesses and compare it with wind models. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
