Dynamical modelling of the Galactic bulge and bar: the Milky Way's bar pattern speed, stellar, and dark matter mass distribution
Matthieu Portail, Ortwin Gerhard, Christopher Wegg +1
We construct a large set of dynamical models of the galactic bulge, bar and inner disk using the Made-to-Measure method. Our models are constrained to match the red clump giant den…
MOA-II Galactic Microlensing Constraints: The Inner Milky Way has a Low Dark Matter Fraction and a Near Maximal Disk
Christopher Wegg, Ortwin Gerhard, Matthieu Portail
Microlensing provides a unique tool to break the stellar to dark matter degeneracy in the inner Milky Way. We combine N-body dynamical models fitted to the Milky Way's Boxy/Peanut…
The old nuclear star cluster in the Milky Way: dynamics, mass, statistical parallax, and black hole mass
Sotiris Chatzopoulos, Tobias Fritz, Ortwin Gerhard +4
We derive new constraints on the mass, rotation, orbit structure and statistical parallax of the Galactic old nuclear star cluster (NSC) and the mass of the supermassive black hole…
