Notes:
We identify this radio source with the bright R = 21.8 magnitude spiral
galaxy located 0.8" to the south of the radio centroid. However, diffuse
optical emission is present directly underneath the centroid of the
radio contours which may be either a separate low surface brightness
galaxy or an indication of tidal disruption of the fainter optical
galaxy to the north.
The spiral is at a redshift of 0.299 and has L8.5 GHz =
1021.9 W/Hz. It is quite red (V – I = 1.3) and has an
H+K magnitude of 18.5. The presence of strong [OII] emission (Cowie
et al. 1997) could be indicative of either star-formation or
nuclear activity. If the steep spectrum (
= 0.8 ± 0.2 )
radio emission is associated with star formation, a rate of
10 M
/yr is
inferred.
