Pseudobulges in Barred S0 Galaxies
Peter Erwin, John E. Beckman, Juan Carlos Vega Beltran
We present preliminary results from an ongoing study of the bulges of S0 galaxies. We show that in a subsample of 14 barred S0 galaxies, fully half the photometrically defined bulg…
When Is a Bulge Not a Bulge? Inner Disks Masquerading as Bulges in NGC 2787 and NGC 3945
Peter Erwin, Juan Carlos Vega Beltran, Alister W. Graham +1
We present a detailed morphological, photometric, and kinematic analysis of two barred S0 galaxies with large, luminous inner disks inside their bars. We show that these structures…
Stellar Nuclear Rings in Barred Galaxies: Fossils of Past Circumnuclear Starbursts?
Peter Erwin, Juan Carlos Vega Beltran, John Beckman
We have found four barred S0 galaxies -- NGC 936, NGC 3945, NGC 4340, and NGC 4371 -- which contain smooth, luminous, purely stellar nuclear rings within their bars. These rings ha…
Double Bars, Inner Disks, and Nuclear Rings in Barred Galaxies
Peter Erwin, Linda S. Sparke, Juan Carlos Vega Beltran +1
We present results of a high-resolution imaging survey of barred S0--Sa galaxies which demonstrate that the central regions of these galaxies are surprisingly complex. We see many…
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…
The Circumnuclear Ring of Ionized Gas in NGC3593
E. M. Corsini, A. Pizzella, J. G. Funes S. J. +2
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…
