The Local Volume HI Survey

ESO 320-G014 (HIPASS J1137-39) is a dwarf irregular galaxy at a TRGB distance of 6.08 ± 0.65 Mpc (Karachentsev et al. 2007), located in the outskirts of the Cen A group. Its closest known companion is the dwarf galaxy HIPASS J1132-32, and its most massive companions are NGC 3621 (HIPASS J1118-32) and Cen A (HIPASS J1324-42). Our ATCA data show a barely resolved HI source centred on the fuzzy stellar body; a faint GALEX UV source is also detected. Deep infrared photometry was obtained by Young et al. (2014). A weak gradient is seen in the HI velocity field, but higher resolution is needed for further analysis of the gas kinematics. We measure F_HI = 2.0 Jy km/s, in agreement with HIPASS (Meyer et al. 2004), and derive M_HI = 1.7 × 10⁷ M_☉.
