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…
The sigma_c-V_c correlation in high and low surface brightness galaxies
A. Pizzella, E. Dalla Bonta', E. M. Corsini +2
We investigate the relation between the central velocity dispersion, sigma_0, and the circular velocity, V_c, in galaxies. In addition to previously available data, we consider an…
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…
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…
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…
Kinematics of Gas and Stars in Early-type 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 disk galaxies. We measured the major axis V and velocity dispersion radia…
