Into the starlight: Learning the Milky Way

Date: 
03/06/2020 - 3:30pm to 5:00pm
Location: 
CP 155
Speaker(s) / Presenter(s): 
Yuan-Sen Ting (IAS)

Understanding physical processes responsible for the formation and evolution of galaxies like the Milky Way is a fundamental but unsolved problem in astrophysics. Most stars are long-lived, using the stars as "fossil records" (what is known as Galactic archaeology) can offer unparalleled insight into the assembly of galaxies.  The landscape of Galactic archaeology is rapidly changing thanks to on-going large-scale surveys (astrometry, photometry, spectroscopy, and asteroseismology), which provide a few orders of magnitude more stars than before. I will discuss various "phenomenological" opportunities enabled by large surveys.  I will also discuss how we can describe substructures in the Milky Way through the lens of deep learning, and how machine learning can maximally harness information from stellar observables.

 

Host: Yan

Colloquium will be held at Chemistry-Physics building (CP), 505 Rose street, room 155.

Refreshments with the speaker will be served at 3:00 pm in CP-179.
