The VIRMOS-VLT Deep Survey: the last 10 billion years of evolution of galaxy clustering
A. Pollo, L. Guzzo, O. Le Fevre +46
We discuss the evolution of clustering of galaxies in the Universe from the present epoch back to z ~ 2, using the first-epoch data from the VIMOS-VLT Deep Survey (VVDS). We presen…
Witnessing the build-up of the colour-density relation
O. Cucciati, A. Iovino, C. Marinoni +50
We investigate the redshift and luminosity evolution of the galaxy colour-density relation using the data from the First Epoch VIMOS-VLT Deep Survey (VVDS) on scales of R=5 h^(-1)M…
Unveiling Dark Matter with HI and Halpha Data - Observational Problems
G. Gentile, D. Vergani, P. Salucci +2
We present combined Halpha+HI rotation curves for a sample of spiral galaxies. Most of the velocity profiles (spectra at single points) in these galaxies are asymmetric, preventing…
Warps and Rotation Curves in Edge-On Galaxies
D. Vergani, G. Gentile, R. -J. Dettmar +2
We present our investigation on the effect of warps on the extraction of rotation curves in edge-on galaxies. The method to derive the rotation curve from the position-velocity dia…
Morphology and kinematics of HI in dust-lane elliptical galaxies
Raffaella Morganti, Tom Oosterloo, Elaine Sadler +1
We present the results of the HI observations of four dust-lane ellipticals. The HI detected is regularly distributed in disks or rings. Moreover, in three of the four objects we h…
