Properties of bars in the local universe
J. Méndez-Abreu, J. A. L. Aguerri, E. M. Corsini
We studied the fraction and properties of bars in a sample of about 3000 galaxies extracted from SDSS-DR5. This represents a volume limited sample with galaxies located between red…
Structural properties of disk galaxies: The intrinsic equatorial ellipticity of bulges
J. Méndez-Abreu, J. A. L. Aguerri, E. M. Corsini +1
The structural parameters of a magnitude-limited sample of 148 unbarred S0-Sb galaxies were derived to study the correlations between bulge and disk parameters as well as the proba…
Satellite Infall and the Growth of Bulges of Spiral Galaxies
M. C. Eliche-Moral, M. Balcells, J. A. L. Aguerri +1
For bulges of spiral galaxies, the concentration, or Sersic index, increases with bulge luminosity and bulge-to-disk ratio B/D (Andredakis, Peletier, & Balcells 1995, MNRAS, 275, 8…
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…
