High-Resolution Rotation Curves and Galaxy Mass Models from THINGS
W. J. G. de Blok, F. Walter, E. Brinks +3
We present rotation curves of 19 galaxies from THINGS, The HI Nearby Galaxy Survey. The high spatial and velocity resolution of THINGS make these the highest quality HI rotation cu…
High Resolution Optical Velocity Fields of 11 Low Surface Brightness Galaxies
Rachel Kuzio de Naray, Stacy S. McGaugh, W. J. G. de Blok +1
We present high resolution two-dimensional velocity fields from integral field spectroscopy along with derived rotation curves for eleven low surface brightness galaxies. We fit NF…
A Limit on the Cosmological Mass Density and Power Spectrum from the Rotation Curves of Low Surface Brightness Galaxies
S. McGaugh, M. Barker, E. de Blok
The concentrations of the cuspy dark matter halos predicted by simulations of cold dark matter are related to the cosmology in which the halos form. Observational constraints on ha…
Star formation and the interstellar medium in low surface brightness galaxies. II. Deep CO observations of low surface brightness disk galaxies
W. J. G. de Blok, J. M. van der Hulst
We present deep, pointed CO() observations of three late-type LSB galaxies. The beam-size was small enough that we could probe different environments (\HI maximum, \H…
Star formation and the interstellar medium in low surface brightness galaxies. I. Oxygen abundances and abundance gradients in low surface brightness disk galaxies
W. J. G. de Blok, J. M. van der Hulst
We present measurements of the oxygen abundances in 64 HII regions in 12 LSB galaxies. We find that oxygen abundances are low. No regions with solar abundance have been found, and…
