HIPASS J1526-51
, also known as HIZOA J1526-51, appears to be a dwarf irregular galaxy
located in the Zone-of-Avoidance. It was first discovered in the Parkes HI
multibeam survey of the Zone of Avoidance (Juraszek et al. 2000). No optical
counterpart has been identified due to the high optical extinction
(AB = 2.30 mag) and high stellar density (Ryan-Weber et al. 2002).
Using our ATCA HI maps we measure a centre position of α,δ(J2000)
= 15:26:22.4, -51:10:30.2. The Local Group velocity of HIPASS J1526-51 is
438 km/s which corresponds to a Hubble distance of 5.7 Mpc. The ATCA data
reveal an extended HI distribution and a peculiar velocity field, hinting at
two distinct components. Its nearest known neighbours are ESO 274-G001 (HIPASS
J1514-46) and ESO 223-G009 (HIPASS J1501-48), both close to 5 degr away. We
measure FHI = 5.0 Jy km/s for HIPASS J1526-51, in agreement with
HIPASS (Koribalski et al. 2004), and derive MHI = 3.8 ×
107 M☉.
