Structural properties of disk galaxies I. The intrinsic ellipticity of bulges
J. Mendez-Abreu, J. A. L. Aguerri, E. M. Corsini +1
(Abridged) A variety of formation scenarios was proposed to explain the diversity of properties observed in bulges. Studying their intrinsic shape can help in constraining the domi…
A Study of Catalogued Nearby Galaxy Clusters in the SDSS-DR4: I. Cluster Global Properties
J. A. L. Aguerri, R. Sanchez-Janssen, C. Munoz-Tunon
We have selected a sample of 88 nearby (z<0.1) galaxy clusters from the SDSS-DR4 with redshift information for the cluster members. We have derived global properties for each clust…
The bar pattern speed of NGC 4431
E. M. Corsini, J. A. L. Aguerri, Victor P. Debattista +3
We present surface photometry and stellar kinematics of NGC 4431, a barred dwarf galaxy in the Virgo cluster undergoing a tidal interaction with one of its neighbors, NGC 4436. We…
