Helium and Iron in X-ray galaxy clusters
arXiv:astro-ph/0610466 · doi:10.1007/978-3-540-73484-0_52
Abstract
I discuss the role of the sedimentation of helium in galaxy cluster cores on the observed X-ray properties and present a history of the metal accumulation in the ICM, with new calculations with respect to my previous work following the recent evidence of a bi-modal distribution of the delay time in Supernovae Type Ia.
