The Local Volume HI Survey (LVHIS)

IC 4316

IC 4316 (HIPASS J1340-28) is a dwarf irregular galaxy at a TRGB distance of 4.41 ± 0.44 Mpc (Karachentsev et al. 2002), located 72.5 arcmin north-east of M 83. The large (mostly red) low surface brightness stellar body resembles that of an early-type galaxy while optical and GALEX UV images of the inner region are typical of dIrr galaxies. Our ATCA HI data show a marginally resolved source with just a hint of gas motions along the N−S axis, well offset from the stellar major axis (see also Lopez-Sanchez et al. 2012). We measure FHI = 2.6 Jy km/s, somewhat more than in HIDEEP (Minchin et al. 2003), and derive MHI = 1.2 × 107 M. Begum et al. (2008) show a barely resolved GMRT HI intensity map of IC 4316.
