IRAS 00182-7112 (F00183-7111) is a high-redshift (z = 0.327) ULIRG
[{nu}L_{nu}_(60 microns) = 10^12.8^L_solar_. It is one of the few
well-studied high FIR luminosity objects having an intermediate radio
excess (u = 1.04). It is a powerful radio source [L_{nu}_(4.8 GHz) =
10^25.6^ W Hz^-1^] that is unresolved in our 1" ATCA beam (<5.8 kpc)
at 8.6 GHz. Norris et al. (1988) detected a compact radio core at 1.66
GHz using the Parkes-Tidbinbilla interferometer. They measured a flux
density of 250 mJy, with fringe spacing ~0.1", which corresponds to
578 pc. The flux density expected for the source at 1.66 GHz, derived
from the observed ATCA flux density at 5 GHz and SUMSS flux density at
843 MHz, is 249 mJy. This strongly suggests that the radio source is
compact, with total extent less than 578 pc. There is evidence for a
weak or obscured AGN from the classification of the optical spectrum
as a LINER (Armus, Heckman, & Miley 1989). Strong mid-infrared
continuum and relatively weak polycyclic aromatic hydrocarbon (PAH,
7.7 microns) emission indicate the presence of an obscured AGN (Tran
et al. 2001).
