High-resolution optical velocity fields of 11 low surface brightness galaxies.

Abstract (from CDS):

We present high-resolution two-dimensional velocity fields from integral field spectroscopy, along with derived rotation curves for 11 low surface brightness galaxies. We fit NFW and pseudoisothermal halo models to the new data combined with previous long-slit and H I data. In most cases, we find the pseudoisothermal halo to better represent the data than the NFW halo, as the NFW concentrations are often lower than expected for a ΛCDM cosmology. We also compare our results to previous studies and find that including the new two-dimensional optical data does not significantly alter the halo parameters but does decrease the uncertainties by roughly a factor of 2.
