      We present Expanded Very Large Array (EVLA) D-array observations of the 21 cm line of neutral hydrogen (H-I) of CIG 292, an isolated SA(s)b galaxy at a distance of similar to 24.3 Mpc. From previous Hi single dish observations ...
    • H I Distribution in Blue Compact Dwarf Galaxies 

      Bravo-Alfaro, H.; Brinks, E.; Kunth, D.; Matias, F. (Astronomical Society of the Pacific, 2000)
      We present VLA HI observations and preliminary results for two dwarf galaxies, Haro 2 (Mrk 33) and Haro 4 (Mrk 36, which are currently experiencing a burst of star formation. We analyze the distribution and kinematics of ...
    • H I Gas in the Environment of the Seyfert Galaxies NGC 6764 and Markarian 1126 

      Wilcots, E.M.; Turnball, M.C.; Brinks, E. (2001-10)

      Studies of the atomic phase of the interstellar medium, via the 21-cm spectral line of neutral hydrogen (H I), play a key role in our attempts to understand the structure and evolution of disk galaxies. We present here ...
    • H I Recycling: Formation of Tidal Dwarf Galaxies 

      Duc, P.A.; Brinks, E. (Astronomical Society of the Pacific, 2001)
      Galactic collisions trigger a number of phenomena, such as transportation inward of gas from distances of up to kiloparsecs from the center of a galaxy to the nuclear region, fueling a central starburst or nuclear activity. ...
