Astronomy Colloquium
Dynamical Structure in the Galactic disk -- a new Decade of Galactic Discovery
Time: 3:30 pm
Place: 4421 Sterling Hall
Speaker: Alice Quillen, Univeristy of Rochester, Astronomy & Astrophysics
Abstract: Soon GAIA observations will increase our knowledge of the positions and velocities of millions of stars in the our Galaxy.
I will explore how star formation, spiral structure, perturbations and remnants from dwarf galaxies, and the Galactic bar cause substructure in local stellar velocity distributions.
I will discuss challenges in better measuring the shape and stellar distribution of the Milky Way, understanding dynamical processes in the disk and its formation and past evolution.
Host: Prof Elena D'onghia
