Riding the Spiral Waves: Implications of Stellar Migration for the Properties of Galactic Disks
Rok Roškar, Victor P. Debattista, Thomas R. Quinn +2
Stars in disks of spiral galaxies are usually assumed to remain roughly at their birth radii. This assumption is built into decades of modelling of the evolution of stellar populat…
Clues to Radial Migration from the Properties of Outer Disks
Rok Roškar, Victor P. Debattista, Thomas R. Quinn +3
The outer disks of galaxies present a unique laboratory for studying the process of disk formation. A considerable fraction of observed disks exhibit a break in their surface brigh…
NMAGIC: Fast Parallel Implementation of a Chi-Squared-Made-to-Measure Algorithm for Modelling Observational Data
Flavio de Lorenzi, Victor Debattista, Ortwin Gerhard +1
We describe a made-to-measure algorithm for constructing N-particle models of stellar systems from observational data (Chi-Squared-M2M), extending earlier ideas by Syer and Tremain…
Bar Dynamical Friction and Disk Galaxy Dark Matter Content
Victor P. Debattista
I present some new results, from simulations and observations, of the constraints bar pattern speeds place on the dark matter content of disk galaxies.
The Bar Pattern Speed in NGC 7079
V. P. Debattista, T. B. Williams
We have used 2D Fabry-Perot absorption-line spectroscopy of the SB0 galaxy NGC 7079 to measure its bar pattern speed, $\om$. As in all previous cases of bar pattern speed measureme…
Fabry-Perot Absorption-Line Spectroscopy of NGC 7079
Victor P. Debattista, T. B. Williams
We report on absorption-line Fabry-Perot spectroscopy of the SB0 galaxy NGC 7079. Our data allow us to determine velocity and dispersion maps, which compare well with the results o…
