Probing Black Hole Disk Atmospheres with EPIC and RGS Observations of 4U 1957+11
Abstract
We propose contemporaneous XMM-Newton and HST-COS observations of the black hole candidate 4U1957+11. We plan to search both the X-ray and UV spectra for evidence of a blue-shifted, magnetized wind, similar to that observed in high-resolution X-ray spectra of GRO J1655-40.
