Description
A Tour of Dust in Galaxies
The last time I came to UT, it was 2015, and I talked almost entirely about molecules in galaxies. Now, I'm 10 years older, and work on even more esoteric problems: dust in galaxies!
But seriously, dust is awesome. It impacts almost every astrophysical observation that you make, is a critical ingredient to thermal balance in the ISM, and is used to trace obscured star formation at all redshifts. I'll present the results from a new model for dust in galaxy simulations that we're pushing, talking about extinction, attenuation, dusty starbursts, the formation of the first dust at z>a bajillion, and an awesome new model for PAHs. And, just because all the cool kids are doing it (especially at UT!), I'll have a few side tours into machine learning and simulation based inference.
