Intracluster Medium Abundances Revisited | | Brad K. Gibson

13 Feb 1998 | | Subject: | astro-ph | | Affiliation: | MSSSO), Emma J. Woolaston (MSSSO | | Abstract: | We examine the origin of heavy elements in the intracluster medium (ICM) of galaxy clusters, concentrating upon the roles played by supernovae (SNe) Types Ia and II. The most accurately determined elemental abundances, Si and Fe, imply a mild predominance of Type II SNe as the source of ICM Fe, contributing approximately 60-80% of its total (and approximately 100% of the alpha-elements). (Currently) intractable uncertainties in measuring X-ray alpha-element ICM abundances, the initial mass function (IMF), and stellar evolution ingredients, make a more precise determination of the Ia:II ICM iron ``ratio’’ impossible. | | Source: | arXiv, astro-ph/9802172 | | Services: | Forum | Review | PDF | Favorites | |
