The work of Professor Krawczynski’s group includes the development of the balloon-borne XL-Calibur scattering X-ray polarimeter scheduled for launch in Summer 2022 from Kiruna (Sweden). The group develops furthermore room temperature and cryogenic X-ray and gamma-ray detectors.The group is a science collaborator of the Imaging X-ray Polarimetry Explorer (IXPE), and uses the Chandra, Swift, NuSTAR, and Fermi X-ray and gamma-ray satellites. The activities of the group include observational and theoretical work focussing on magnetars, stellar mass and supermassive black holes, blazars, and gravitationally lensed quasars.
