I study the Physics of accretion of matter onto compact objects with X-ray observations (XMM-Newton, NuSTAR, Chandra). I specifically focus on super-Eddington accretion and the production of high-velocity winds in these systems at all mass scales. This includes neutron stars and stellar mass black holes in ultraluminous X-ray sources, and (likely) supercritical supermassive black holes in Narrow-line Seyfert 1 galaxies.
