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…
Kinematics and photometry as complementary tools in the study of barred galaxies
Juan Carlos Vega Beltran, Peter Erwin, John Beckman +4
Recent advances in observational techniques and theoretical modelling of galaxy kinematics allow us to use more than just optical morphology to discern the structure and dynamics o…
The Quest for the Dominant Stellar Population in the Giant Elliptical NGC 5018
Lucio M. Buson, Francesco Bertola, David Burstein +1
Newly obtained HST/WFPC2 images of the disturbed elliptical galaxy NGC 5018 show that the average amount of internal reddening due to the its complex ``dust web'' is as low as E(B-…
NGC 4672: a new case of an early-type disk galaxy with an orthogonally decoupled core
M. Sarzi, E. M. Corsini, A. Pizzella +4
We report the case of the early-type disk galaxy NGC 4672 as a new example of a galaxy characterized by the orthogonal geometrical decoupling between bulge and disk. The morphologi…
Minor-Axis Stellar Velocity Gradients in Disk and Polar-Ring Galaxies
F. Bertola, E. M. Corsini
Kinematical decoupling between two components of a galaxy suggests the occurrence of a second event. In disk galaxies it is usually observed as a counterrotation of the stellar dis…
Correlation between kinematics and Hubble Sequence in disk galaxies?
J. C. Vega Beltran, E. Pignatelli, W. W. Zeilinger +4
We present a comparison between ionized gas and stellar kinematics for a sample of 5 early-to-intermediate disc galaxies. We measured the major axis V and sigma radial profiles for…
