Central rotations of Milky Way Globular Clusters
Maximilian H. Fabricius, Eva Noyola, Surangkhana Rukdee +6
Most Milky Way globular clusters (GCs) exhibit measurable flattening, even if on a very low level. Both cluster rotation and tidal fields are thought to cause this flattening. Neve…
Re-growth of stellar disks in mature galaxies: The two component nature of NGC 7217 revisited with VIRUS-W
Maximilian H. Fabricius, Lodovico Coccato, Ralf Bender +6
Previous studies have reported the existence of two counter-rotating stellar disks in the early-type spiral galaxy NGC7217. We have obtained high-resolution optical spectroscopic d…
The stellar kinematics and populations of boxy bulges: cylindrical rotation and vertical gradients
Michael J. Williams, Michel Zamojski, Martin Bureau +4
Boxy and peanut-shaped bulges are seen in about half of edge-on disc galaxies. Comparisons of the photometry and major-axis gas and stellar kinematics of these bulges to simulation…
The Tully-Fisher relations of early-type spiral and S0 galaxies
Michael J. Williams, Martin Bureau, Michele Cappellari
We demonstrate that the comparison of Tully-Fisher relations (TFRs) derived from global HI line widths to TFRs derived from the circular velocity profiles of dynamical models (or s…
Dark matter and the Tully-Fisher relations of spiral and S0 galaxies
Michael J. Williams, Martin Bureau, Michele Cappellari
We construct mass models of 28 S0-Sb galaxies. The models have an axisymmetric stellar component and a NFW dark halo and are constrained by observed Ks-band photometry and stellar…
Kinematic constraints on the stellar and dark matter content of spiral and S0 galaxies
Michael J. Williams, Martin Bureau, Michele Cappellari
(Abridged) We present mass models of a sample of 14 spiral and 14 S0 galaxies that constrain their stellar and dark matter content. For each galaxy we derive the stellar mass distr…
