On the Dynamics of the Inclination Instability

Ann-Marie Madigan, Alexander Zderic, Michael McCourt +1

Axisymmetric disks of eccentric Kepler orbits are vulnerable to an instability which causes orbits to exponentially grow in inclination, decrease in eccentricity, and cluster in th…

The impact of magnetic fields on thermal instability

Suoqing Ji, S. Peng Oh, Michael McCourt

Cold () gas is very commonly found in both galactic and cluster halos. There is no clear consensus on its origin. Such gas could be uplifted from the cen…

Dynamical Properties of Eccentric Nuclear Disks: Stability, Longevity, and Implications for Tidal Disruption Rates in Post-Merger Galaxies

Ann-Marie Madigan, Andrew Halle, Mackenzie Moody +3

In some galaxies, the stars orbiting the supermassive black hole take the form of an eccentric nuclear disk, in which every star is on a coherent, apsidally-aligned orbit. The most…

Resonant line transfer in a fog: Using Lyman-alpha to probe tiny structures in atomic gas

Max Gronke, Mark Dijkstra, Michael McCourt +1

Motivated by observational and theoretical work which both suggest very small scale (pc) structure in the circum-galactic medium of galaxies and in other environments…

From Mirrors to Windows: Lyman-Alpha Radiative Transfer in a Very Clumpy Medium

Max Gronke, Mark Dijkstra, Michael McCourt +1

Lyman-Alpha (Ly) is the strongest emission line in the Universe and is frequently used to detect and study the most distant galaxies. Because Lya is a resonant line, photons typ…

A Characteristic Scale for Cold Gas

Michael McCourt, S. Peng Oh, Ryan M. O'Leary +1

We find that clouds of optically-thin, pressure-confined gas are prone to fragmentation as they cool below K. This fragmentation follows the lengthscale $\sim{c}_{\text{…
