SDSS match?

The few I've found that are this bright in IR are typically matched in SDSS with either a large, obvious galaxy or a bright "star" signature. This one seems to have neither. I had a hard time even finding a candidate match. SDSS J112016.18+435451.4?

Yep, that's it.
Quite remarkable too; it's got a spectrum: z = 0.612, very strong [OIII] lines, as well as H-beta (in emission), [OII], and [NeIII]. This is one very big, very bright galaxy. It may be that the line ratios say 'narrow-line AGN'; if not, then there's an awful lot of star-formation happening. I can't tell - just by eyeballing it - but the continuum looks quite flat, not the least bit like a 'dead and red' elliptical. Oh, and it's a 6C radio object, as you'd expect given how strong the radio emission is.
Put this one in the 'DEFINITELY a candidate for follow-up!' 😃

Heh, Jean, your information is great for making me feel like a "real scientist"!
It'll probably take me the next two weeks to track back and figure out what everything you said meant … but hey, that's why this is a hobby 😃
