Why is the Galactic disk so cool?
Chris Hamilton, Shaunak Modak, Scott Tremaine
The bulk of old stars in the Galactic disk have migrated radially by up to several kpc in their lifetimes, yet the disk has remained relatively cool, i.e., the ratio of radial heat…
The Black Hole Mass and Photometric Components of NGC 4826
Kayhan Gültekin, Karl Gebhardt, John Kormendy +6
We present IR photometry and HST imaging and spectroscopy of Sab galaxy NGC 4826. Schwarzschild dynamical modeling is used to measure its central black hole mass . Photometric d…
Galactokinetics
Chris Hamilton, Shaunak Modak, Scott Tremaine
Galactic disks lie at the heart of many of the most pressing astrophysical puzzles. There are sophisticated kinetic theories that describe some aspects of galaxy disk dynamics, but…
Iron Snails: non-equilibrium dynamics and spiral abundance patterns
Neige Frankel, David W. Hogg, Scott Tremaine +2
Galaxies are not in a dynamical steady state. They continually undergo perturbations, e.g., from infalling dwarf galaxies and dark-matter substructure. After a dynamical perturbati…
Studying Binary Formation under Dynamical Friction Using Hill's Problem
Mark Dodici, Scott Tremaine
Using the equations of motion from Hill's problem, with added accelerations for different forms of dynamical friction, we provide the (to-date) broadest scale-free study of frictio…
