Revisiting the (V/sigma)-epsilon anisotropy diagram of early-type galaxies using integral-field kinematics
M. Cappellari, R. Bacon, M. Bureau +11
We use integral-field observation of the stellar kinematics obtained with SAURON in combination with Schwarzschild dynamical models to revisit our understanding of the classic (V/s…
The Nuclei of Late-type Spiral Galaxies
T. Boeker, C. -J. Walcher, H. -W. Rix +8
We summarize some recent results from our observational campaign to study the central regions of spiral galaxies of late Hubble type (Scd - Sm). These disk-dominated, bulgeless gal…
Central DM density cuspiness in LSB's: a stellar kinematics approach
A. Pizzella, E. M. Corsini, F. Bertola +4
We present preliminary results from spectroscopic observations of a sample of 11 low surface brightness galaxies (LSB). We measured the stellar and gaseous kinematics along their m…
Measuring Black Hole Masses Using Ionized Gas Kinematics
Aaron J. Barth, Marc Sarzi, Luis C. Ho +5
We describe techniques for measuring the central masses of galaxies using emission-line kinematics observed with the Hubble Space Telescope. For accurate results, it is necessary t…
Supermassive Black Holes from the SUNNS survey
Marc Sarzi, Hans-Walter Rix, Joseph C. Shields +5
We report three new accurate mass measurements for the supermassive black holes hosted by the early-type disk galaxies NGC2787, NGC4459 and NGC4596. The targets were selected from…
Variability in LINERs
J. C. Shields, H. -W. Rix, D. H. McIntosh +6
A small number of LINERs have been seen to display variable H-alpha emission with a very broad, double-peaked profile. Recent observations with the Hubble Space Telescope indicate…
