Elemental Abundances in X-ray Binary Outflows
Noa Keshet, Ehud Behar, Jon M. Miller
Line resolved X-ray spectra of outflows from X-ray binaries are interesting since they provide quantifiable measures of the accreted material on to the compact object (black hole o…

Supernova Archaeology with X-Ray Binary Winds -- The Case of GRO J1655-40
Noa Keshet, Ehud Behar, Timothy R. Kallman
Supernovae are responsible for the elemental enrichment of the galaxy and some are postulated to leave behind a black hole. In a stellar binary system the supernova pollutes its co…

Ionization Distributions in Outflows of Active Galaxies: Universal Trends and Prospect of Future XRISM Observations
Noa Keshet, Ehud Behar
The physics behind the ionization structure of outflows from black holes is yet to be fully understood. Using archival observations with the Chandra\HETG gratings over the past two…
