Constraining the Mass Profiles of Stellar Systems: Schwarzschild Modeling of Discrete Velocity Datasets
Julio Chanamé, Jan Kleyna, Roeland van der Marel
(ABRIDGED) We present a new Schwarzschild orbit-superposition code designed to model discrete datasets composed of velocities of individual kinematic tracers in a dynamical system.…
M31 Transverse Velocity and Local Group Mass from Satellite Kinematics
Roeland P. van der Marel, Puragra Guhathakurta
We present several different statistical methods to determine the transverse velocity vector of M31. The underlying assumptions are that the M31 satellites on average follow the mo…
The Toomre Sequence Revisited with HST/NICMOS: Nuclear Brightness Profiles and Colors of Interacting and Merging Galaxies
Joern Rossa, Seppo Laine, Roeland P. van der Marel +4
We discuss the near-infrared properties of the nuclei in the 11 merging galaxies of the Toomre sequence, based on high spatial resolution J, H, and K imaging data using NICMOS onbo…
