""Four Problems in Trying to Form Galaxies(and how ISM Physics can Save Us)""

Speaker's website »

Building a comprehensive picture for the evolution of galaxies
from early times through present epoch requires understanding a huge
dynamic range of physical processes.  With observations ranging from
detections of galaxies less than a billion years after the Big Bang to
stellar and molecular cloud mass spectra in the Milky Way, the challenge
has been to develop a concordance theory for galaxy formation than
simultaneously explains this diverse range of observed galaxy properties
across cosmic epoch.  At the heart of many of the central questions in the
astrophysics of galaxy evolution lies the physics of the interstellar
medium, and galactic-scale star formation. In this talk, I will describe
how understanding the complex interplay between small scale star formation
physics and global galaxy evolution processes can lead to considerable
insight in long-standing problems in both fields.
