ESO 272-G025 (HIPASS
J1443-44) is a dwarf irregular galaxy located in the outskirts of the
Cen A group at a Hubble distance of 5.9 Mpc. Its nearest neighbour is most
likely the galaxy ESO 223-G009 (HIPASS J1501-48). Our ATCA data show a barely
resolved HI source centred on the bright and compact optical body; no rotation
is discernible in our velocity field (see also Bouchard et al. 2007). Galactic
cirrus filaments are visible in the optical image. We measure FHI
= 1.6 Jy km/s, in agreement with HIPASS (Meyer et al. 2004), and derive
MHI = 1.3 × 107 M☉. Reduzzi &
Rampazzo (1995) suggest ESO 272-G025 has an extended low-surface brightness
disc or is possibly a galaxy pair. ESO 272-G025 shows clumpy and diffuse
Hα emission (Kaisin et al. 2007; Cote et al. 2009), with an estimated
star formation rate of 1.5 × 10-3 M☉/yr.
