Dr. Krawczynski works on experimental and theoretical astroparticle physics. Dr. Krawczynski's experimental work includes the development of the balloon-borne X-Calibur scattering X-ray polarimeter scheduled for launch in Fall 2016 (Fort Sumner, NM ) and 2018/2019 (McMurdo, antarctic). Furthermore, he works on the ground-based gamma-ray telescopes VERITAS and CTA, on the development of semiconductor X-ray detectors, and on the development of noble gas dark matter detectors. On the theoretical side, Krawczynski has studied general properties of radiation processes, the observational appearance of black holes (based on General Relativistic ray tracing studies), and on models describing the continuum emission from the ultrafast outflows of mass accreting black holes. Krawczynski's experimental and theoretical work aims at using astrophysical observations to test the Standard Model of Particle Physics and to probe General Relativity in the strong gravity regime. The astrophysical sources of Krawczynski's studies include galactic and extragalactic black holes, neutron stars, gamma-ray bursts and galaxy clusters.
