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.
