The Local Volume HI Survey (LVHIS)

ESO 321-G014

ESO 321-G014 (HIPASS J1214-38) is a dwarf irregular galaxy (type IABm) at a TRGB distance of 3.18 ± 0.23 Mpc (Dalcanton et al. 2009), located in the outskirts of the Cen A group. Its nearest known neighbour, the galaxy ESO 379-G024, lies three degrees away. Using our ATCA HI data we measure FHI = 5.1 Jy km/s, more than three times the HI emission detected by Begum et al. (2008) with the GMRT. The HIPASS FHI value of 6.4 ± 1.6 Jy km/s (Koribalski et al. 2004) agrees within the uncertainties. We derive an HI mass of 1.2 × 107 M. We find the HI distribution to be quite symmetric apart from small deviations of the velocity field towards the northern end. The stellar distribution has a peculiar arrow shape (very prominent in GALEX UV images) with star formation most prominent in the southern part. Bouchard et al. (2009) present an Hα image, indicating weak emission along the galaxy minor axis.
