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.
