Frank Winkler receives two grants from NASA’s Space Telescope Science Institute for collaborative research

Frank Winkler (Emeritus Professor, Physics) has been awarded funding from the NASA-funded Space Telescope Science Institute for his role in two collaborative research projects, both of which entail new observations using the Hubble Space Telescope. One project, entitled Thermal Equilibration and Cosmic-Ray Acceleration in Astrophysical Shocks: UV Spectra of the SN1006 Remnant, will combine forthcoming Hubble ultraviolet spectra with new data Winkler hopes to gather at the 6.5 meter Magellan telescope in Chile in April, to explore the fundamental physics of shock waves in a cosmic environment. The other project, entitled State Transitions of the Ultra-luminous X-ray Source in M83, is intended as a follow-up to better understand a highly unusual object in the “nearby” (15 million light years away) galaxy M83, where matter falling into a black hole produces so much radiation that fundamental laws of physics are close to being violated. The projects involve collaboration with colleagues at the Harvard-Smithsonian Center for Astrophysics, Johns Hopkins University, and Curtin University in Australia.
