The Local Volume HI Survey

ESO 364-G?029 (HIPASS J0605-33) is an irregular looking barred Magellanic dwarf galaxy at a Hubble distance of 7.6 Mpc. Its nearest neighbour is the dwarf galaxy ATCA J060511-332534 (v_sys ~ 830 km/s; F_HI ~ 1 Jy km/s), 21.9 arcmin away, detected here. Other known neighbours are AM 0605-341 (HIPASS J0607-34) and NGC 2188 (HIPASS J0610-34) at projected distances of 70.2 arcmin and 82.5, respectively. Our ATCA maps show a regularly rotating, well-resolved HI disc, encompassing the very irregular-shaped low-surface brightness stellar body. We measure F_HI = 22.3 Jy km/s, somewhat larger than the HIPASS F_HI (Koribalski et al. 2004), and derive M_HI = 1.2 × 10⁸ M_☉. For a detailed study of ESO 364-G?029, including a comparison with the LMC and other dwarf irregular galaxies see Kouwenhoven et al. (2007).
