Frank Winkler receives grant 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 a collaborative research project involving researchers at Curtin University in Australia and Johns Hopkins University. This project entails observations from the Hubble Space Telescope and is titled Diagnosing the super-Eddington accretion/outflow regime using the microquasar MQ1 in M83. The goal of the observations, which come as a follow-up to previous studies from Hubble and from NASA’s Chandra X-ray Observatory, is to better understand an unusual black hole in the southern spiral galaxy M83, also known as the southern pinwheel. Previous studies suggest that the black hole provides the energy source for radiation in excess of what simple physics models allow (the “Eddington limit”) , and has done so for thousands of years. The team hopes to learn how this is possible, or else why this interpretation may be incorrect.
