Title:
Rotation Curves of Disk Galaxies: New Perspectives
Date: Monday, October 22nd, 2007
Time: 12:00
Venue: Villa Bazzoni

Abstract:
I will first present recent results of our ongoing
study of galaxy kinematics using rotation curves, with which we
explore the central density distributions of the dark halos. In the
second part of my talk I will then report on a project to investigate
galaxy warps. We have developed a new technique allowing a reliable
parametrization of the warp geometries using the HI data cubes. With
these it is possible to find the rules which warps 'obey to', and to
shed light on the overall distribution of Dark Matter in galaxies.
