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…
Fast bars in SB0 galaxies
Enrico Maria Corsini, J. A. L. Aguerri, Victor P. Debattista
We measured the bar pattern speed in a sample of 7 SB0 galaxies using the Tremaine-Weinberg method. This represents the largest sample of galaxies for which bar pattern speed has b…
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…
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…
