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...
