SUMMARY:Four Problems in Trying to Form Galaxies(and how ISM Physics c
an Save US)\, Astronomy Colloquium\, Desika Narayanan\, Haverford Coll
ege
DESCRIPTION:Building a comprehensive picture for the evolution of gala
xies
\nfrom early times through present epoch requires understandi
ng a huge dynamic range of physical processes. With observations rang
ing from detections of galaxies less than a billion years after the Bi
g Bang to stellar and molecular cloud mass spectra in the Milky Way\,
the challenge has been to develop a concordance theory for galaxy form
ation than simultaneously explains this diverse range of observed gala
xy properties across cosmic epoch. At the heart of many of the centra
l questions in the astrophysics of galaxy evolution lies the physics o
f the interstellar medium\, and galactic-scale star formation. In this
talk\, I will describe how understanding the complex interplay betwee
n small scale star formation physics and global galaxy evolution proce
sses can lead to considerable insight in long-standing problems in bot
h fields.
