“X-ray Dust Tomography: The New Frontier in Galactic Exploration” by Sebastian Heinz, Ph.D., Fluno Bascom Professor, Department Chair, Astronomy Department, University of Wisconsin-Madison

Abstract:  Light echoes from Galactic transients offer a powerful new tool to measure distances, map Galactic structure, and probe the properties of interstellar dust. I will discuss the physics of dust scattering using recent examples of extraordinarily bright echoes from Circinus X-1 and V404 Cygni and the prospects for future echo searches.
