ABSTRACT: Many galaxies exhibit the need for a continual source of star formation fuel. Halo gas is a common feature of these galaxies, though utilizing this gas as fuel may require the gas to go through multiple phases. I will discuss new...

ABSTRACT: With the imminent start of Advanced LIGO/VIRGO observations, and the less imminent but much hoped-for advent of LISA, gravitational wave science will transition from a specialty of theoretical astrophysics and experimental interferometry...

ABSTRACT: I will review our present understanding of super-Eddington atmospheres, as borne from theory and observations. In particular, I will show how atmospheres can sustain super-Eddington fluxes, while accelerating only ``moderate'' mass loss...

ABSTRACT: The 20th Century has seen a notable temperature rise, generally attributed to the greenhouse effect of anthropogenic gases, and a future "business as usual" policy is generally believed to be catastrophic. I will show, however, that the...

ABSTRACT: Recent observations have shown that in many exoplanetary systems, the spin axis of the parent star is misaligned with the angular momentum axis of the planet's orbit. This is unexpected as planets are formed in protostellar disks which are...
