Dark matter in early-type spiral galaxies: the case of NGC 2179 and of NGC 2775. (1999)
Corsini, E.M., Pizzella, A., Sarzi, M., Cinzano, P., Vega Beltran, J., Funes, J., ...
Kinematics of Gas and Stars in Early-type Disk Galaxies (1998)
Beltran, J. C. Vega, Pignatelli, E., Zeilinger, W. W., Pizzella, A., Corsini, E. M., Bertola, F., ...
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 radial profiles for both...
Dark matter in early-type spiral galaxies: the case of NGC 2179 and of NGC 2775 (1998)
Corsini, E. M., Pizzella, A., Sarzi, M., Cinzano, P., Beltran, J. C. Vega, Funes, J. G., ...
We present stellar and ionized-gas velocity curves and velocity dispersion profiles for the Sa galaxies NGC 2179 and NGC 2775. Using their luminosity profiles and modeling both their stellar and...
Circumnuclear Keplerian Disks in Galaxies (1998)
Bertola, F., Cappellari, M., Funes, J. G., Corsini, E. M., Pizzella, A., Beltran, J. C. Vega
In this paper we demonstrate the possibility of inferring the presence of Keplerian gaseous disks using optical ground-based telescopes properly equipped. We have modeled the peculiar bidimensional...
The Circumnuclear Ring of Ionized Gas in NGC3593 (1998)
Corsini, E. M., Pizzella, A., Beltran, J. C. Vega, Bertola, F.
We present the results of narrow-band Halpha+NII imaging of the early-type spiral NGC3593 in combination with a study of the flux radial profiles of the NII (lambda: 654.80, 658.34 nm), Halpha, and...
Beltran, J. C. Vega, Zeilinger, W. W., Amico, P., Schultheis, M., Corsini, E. M., ...
Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (P.A.=5, 50, 95, 125 and 155 degrees) of the nearby...
Counterrotation in Galaxies (1998)
The phenomenon of counterrotation is observed when two galaxy components have their angular momenta projected antiparallel onto the sky. It follows that if the two components rotate around the same...
Figure-of-eight velocity curves: UGC10205 (1997)
Vega, J. C., Corsini, E. M., Pizzella, A., Bertola, F.
We measured the velocity curve and the velocity dispersion profile of the ionized gas along the major axis of the edge-on galaxy UGC~10205. The observed kinematics extends up to about 40 arcsec from...
Figure-of-eight velocity curves: UGC 10205 (1997)
J.C. Vega, E. M. Corsini, A. Pizzella, F. Bertola, Francesca Rampazzi
We measured the velocity curve and the velocity dispersion profile of the ionized gas along the major axis of the edge-on galaxy UGC 10205. The observed kinematics extends up to about 40 00 from the...
