The experimental work of Professor Krawczynski includes the development of the balloon-borne X-Calibur scattering X-ray polarimeter scheduled for launch in December 2018 from McMurdo (Antarctic). 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 include X-ray observations of stellar mass and supermassive black holes, blazars, and gravitationally lensed quasars.
