Rotation Curves and Mass Distribution in spiral galaxies:
Using high-angular resolution CO-line observations combined with current
kinematical data in the disk, we derive high-accuracy rotation curves for
spiral galaxies. The RC are used to calculate the mass distributions, and
are compared with luminoisty profiles. From these analyses, we investigate
the distribution of dark matter, not only in the halo but also in the disk,
bulge and the central core region.
