Surveying the Multi-Scale Star Formation Process
Presented by Ian Stephens
Harvard-Smithsonian Center for Astrophysics

Monday August 6, 2018
12:00 noon in 169-336

The formation of stars from the interstellar medium is a complicated, multi-scale process. Survey astronomy can be used to statistically constrain the star formation process. In this talk, I will focus on some of my recent star formation surveys, showing multi-scale scientific results. I will start with scales of entire galaxies, zoom-in to clouds and clumps, continue to filaments and envelopes, and end with disks and dust grains. Among the results, I will show how dense gas of galaxies is related to the constituent dense clumps, how angular momentum is transferred from filaments to protostars, and how (sub)millimeter polarized emission can be used to constrain grain growth in disks. I also will give a quick preview of some upcoming surveys.
