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{…
Simulations of Magnetic Fields in Tidally-Disrupted Stars
James Guillochon, Michael McCourt
We perform the first magnetohydrodynamical simulations of tidal disruptions of stars by supermassive black holes. We consider stars with both tangled and ordered magnetic fields, f…
The Impact of Star Formation Feedback on the Circumgalactic Medium
Drummond Fielding, Eliot Quataert, Michael McCourt +1
We use idealized 3D hydrodynamic simulations to study the dynamics and thermal structure of the circumgalactic medium (CGM). Our simulations quantify the role of cooling, stellar f…
Using gas clouds to probe the accretion flow around SgrA*: G2's delayed pericenter passage
Ann-Marie Madigan, Michael McCourt, Ryan O'Leary
We study the dynamical evolution of the putative gas clouds G1 and G2 recently discovered in the Galactic center. Following earlier studies suggesting that these two clouds are par…
