The Coma Cluster hard X-ray spectrum revisited: still no evidence for a hard tail

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/124010In this note, we reply to Fusco-Femiano et al. (2004) and Fusco-Femiano et al. (2006), who cast doubts on our analysis of the PDS observations of the Coma Cluster which we describe in Rossetti & Molendi (2004). We discuss the main issues in Fusco-Femiano et al. (2006) and we confirm that the available data do not allow to firmly establish the presence of a non-thermal component in the hard X-ray spectrum of the Coma cluster.electronic pre-print only, 5 pages, 3 figuresAstrophysicsThe Coma Cluster hard X-ray spectrum revisited: still no evidence for a hard tailtext
