ESO 325-G?011
ESO 325-G?011 (HIPASS
J1345-41) is a Magellanic barred irregular galaxy at a TRGB distance
of 3.40 ± 0.39 Mpc (Karachentsev et al. 2002). Its nearest neighbour
appears to be the galaxy NGC 5237 at a projected distance of 100.7 arcmin,
while the giant elliptical Cen A is nearly 4 degrees away. Our ATCA HI maps
show a well-resolved, rather regular rotating disc. ESO325-G?011's HI flux
density and velocity dispersion are somewhat higher at the north-western
(receding) side, which also shows minor asymmetries in the velocity field.
The stellar brightness is also significantly higher on the HI-bright side.
Using tilted-ring modelling Kirby et al. (2012), who provide a detailed
description of ESO325-G?011, find vrot = 46 km/s (for PA = 302
degr, i = 42 degr) at Rmax = 3.1 kpc, similar to Cote et al.
(2000). We measure FHI = 26.4 Jy km/s, in agreement with HIPASS
(Koribalski et al. 2004). Cote et al. (2009) identify eight HII regions
across the stellar disc and derive SFR = 2.5 × 10-3
M☉/yr.
