"Piercing the Dusty Veil: Mapping the Structure of Spiral Galaxies"
Our own Milky Way galaxy is known to have a remarkably subtle disk structure in which stars occur in multiple very thin layers. Andrew will explain how he uses advanced modeling techniques and high-resolution near-infrared imaging from UW's own WIYN telescope to study the detailed anatomy of other galaxies and compare them to our own. Mapping this structure is essential to understanding how spiral galaxies form and evolve.
