    • The central slope of dark matter cores in dwarf galaxies : simulations versus THINGS 

      Oh, S.H.; Brook, C.; Governato, F.; Brinks, E.; Mayer, L.; de Blok, W.J.G.; Brooks, A.; Walter, F. (2011)
      We make a direct comparison of the derived dark matter (DM) distributions between hydrodynamical simulations of dwarf galaxies assuming ACDM cosmology and the observed dwarf galaxies sample from the THINGS survey in terms ...

    • Dark and luminous matter in THINGS dwarf galaxies 

      Oh, S.H.; de Blok, W.J.G.; Brinks, E.; Walter, F.; Kennicutt, R.C. (2011)
      We present mass models for the dark matter component of seven dwarf galaxies taken from "The H I Nearby Galaxy Survey" (THINGS) and compare these with those taken from numerical Λ cold dark matter (ΛCDM) simulations. The ...

    • The Gas Phase in a Low Metallicity ISM 

      Brinks, E.; Oh, S.H.; Bagetakos, I.; Bigiel, F.; Leroy, A.; Usero, A.; Walter, F.; de Blok, W.J.G.; Kennicutt, R.C. (2008)
      We present several results from our analysis of dwarf irregular galaxies culled from The HI Nearby Galaxy Survey (THINGS). We analyse the rotation curves of two galaxies based on “bulk” velocity fields, i.e. velocity maps ...

    • High-resolution dark matter density profiles of THINGS dwarf galaxies: correcting for non-circular motions 

      Oh, S.H.; de Blok, W.J.G.; Walter, F.; Brinks, E. (2008)

    • High-resolution rotation curves and galaxy mass models from THINGS 

      de Blok, W.J.G.; Walter, F.; Brinks, E.; Trachternach, C.; Oh, S.H.; Kennicutt, R.C. (2008)
      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 ...

    • Little Things 

      Hunter, D. A.; Ficut-Vicas, D.; Ashley, T.; Brinks, E.; Cigan, P.; Elmegreen, B. G.; Heesen, V.; Herrmann, K. A.; Johnson, M.; Oh, S.H.; Rupen, M. P.; Schruba, A.; Simpson, C.E.; Walter, F.; Westpfahl, D. J.; Young, L. M.; Zhang, H.-X. (2012-11)
      We present LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The H I Nearby Galaxy Survey), which is aimed at determining what drives star formation in dwarf galaxies. This is a multi-wavelength survey of 37 ...

    • The Stellar and Gas Kinematics of the LITTLE THINGS Dwarf Irregular Galaxy NGC 1569 

      Johnson, M.; Hunter, D. A.; Oh, S.H.; Zhang, H.-X.; Elmegreen, B.; Brinks, E.; Tollerud, E.; Herrmann, K. (2012-11)
      In order to understand the formation and evolution of Magellanic-type dwarf irregular (dIm) galaxies, one needs to understand their three-dimensional structure. We present measurements of the stellar velocity dispersion ...
