The Effect of General Relativistic Precession on Tidal Disruption Events from Eccentric Nuclear Disks
Heather N. Wernke, Ann-Marie Madigan
An eccentric nuclear disk consists of stars moving on apsidally-aligned orbits around a central black hole. The secular gravitational torques that dynamically stabilize these disks…

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…

Going with the flow: using gas clouds to probe the accretion flow feeding Sgr A*
Michael McCourt, Ann-Marie Madigan
The massive black hole in our galactic center, Sgr A*, accretes only a small fraction of the gas available at its Bondi radius. The physical processes determining this accretion ra…
