High-Resolution Rotation Curves and Galaxy Mass Models from Things

de Blok, W J G; Walter, Fabian; Brinks, Elias; Trachternach, C; Oh, Se; Kennicutt, Robert C

Description

We present rotation curves of 19 galaxies from The H I Nearby Galaxy Survey (THINGS). The high spatial and velocity resolution of THINGS make these the highest quality H I rotation curves available to date for a large sample of nearby galaxies, spanning a wide range of H I masses and luminosities. The high quality of the data allows us to derive the geometric and dynamical parameters using H I data alone. We do not find any declining rotation curves unambiguously associated with a cut-off in...[Show more]
