HIPASS J1351-47
is a dwarf irregular galaxy at α,δ(J2000) = 13:51:21.2,
-46:59:53.0 as measured using our ATCA HI data. It was discovered by Banks et
al. (1999) who measured vsys = 530 km/s. Its TRGB distance of =
5.73 ± 0.73 Mpc (Karachentsev et al. 2007) is similar to that of HIPASS
J1348-37; both are located in the outskirts of the Cen A Group. Its nearest
neighbours appear to be several dSph galaxies, for example LEDA 166179. The
low Local Group velocity (vLG = 291 km/s) of HIPASS J1351-47
indicates an infall velocity of ~140 km/s towards the group. Our ATCA HI data
show a marginally resolved source and hint at a kinematic PA of ~45 degr. We
measure FHI = 3.6 Jy km/s, in agreement with HIPASS (Meyer et al.
2004), and derive an HI mass of 2.8 × 107 M☉.
