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…
The Bar-Halo Interaction in SB Galaxies
Victor P. Debattista, J. A. Sellwood
We describe fully self-consistent N-body experiments of barred galaxies with massive halos. A rotating bar is braked through dynamical friction with the halo, which occurs on a sho…
