We analyse archival XMM-Newton and Chandra observations of some dwarf MW satellites (Leo T, Fornax, and Ursa Minor) with the aim to fully characterize the X-ray source population (in most of the cases background AGNs) detected towards the targets. We also searched for intermediate mass black holes expected to be hosted in the center of the galaxies. While for Leo T the quality of the data did not allow any useful analysis, we have hints of the existence of IMBHs in Fornax and Ursa Minor.

Abstract
We analyse archival XMM-Newton and Chandra observations of some dwarf MW satellites (Leo T, Fornax, and Ursa Minor) with the aim to fully characterize the X-ray source population (in most of the cases background AGNs) detected towards the targets. We also searched for intermediate mass black holes expected to be hosted in the center of the galaxies. While for Leo T the quality of the data did not allow any useful analysis, we have hints of the existence of IMBHs in Fornax and Ursa Minor.File in questo prodotto:
