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{…
Magnetized Gas Clouds can Survive Acceleration by a Hot Wind
Michael McCourt, Ryan M. O'Leary, Ann-Marie Madigan +1
We present three-dimensional magnetohydrodynamic simulations of magnetized gas clouds accelerated by hot winds. We initialize gas clouds with tangled internal magnetic fields and s…
Two paths of cluster evolution: global expansion versus core collapse
Ryan M. O'Leary, Steven W. Stahler, Chung-Pei Ma
All gravitationally bound clusters expand, due to both gas loss from their most massive members and binary heating. All are eventually disrupted tidally, either by passing molecula…
The Peculiar Pulsar Population of the Central Parsec
Jason Dexter, Ryan M. O'Leary
Pulsars orbiting the Galactic center black hole, Sgr A*, would be potential probes of its mass, distance and spin, and may even be used to test general relativity. Despite predicti…
