|Abstract: ||We present high resolution two dimensional velocity fields
from integral field spectroscopy along with derived rotation curves for
nine low surface brightness galaxies. This is a positive step forward in
terms of both data quality and number of objects studied. We fit NFW
and pseudo-isothermal halo models to the observations. We find that
the pseudo-isothermal halo better represents the data in most cases
than the NFW halo, as the resulting concentrations are lower than
would be expected for CDM.|
