Photometry and Kinematics of Self-Gravitating Eccentric Nuclear Disks
Heather N. Wernke, Ann-Marie Madigan
The Andromeda Galaxy hosts an elongated nucleus with (at least) two distinct brightness peaks. The double nucleus can be explained by the projection of a thick, apsidally-aligned e…

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…
