What is this?

This looks like a lobe, but only shows up in radio, so what is it?

These are two jets ejected in opposite directions from the vicinity of the central black hole. They will create these lobes you can see here. Now, you will see these lobes only in radio waves. Other wavelengths may of course show some other signatures like shocks or bubbles in X-rays for example, but radio lobes are you see them here are radio frequency structures.

What would be considered the IR source of these radio lobes?

Look for an IR source just underneath the radio contours. Ideally the IR source would lie just halfway between the two lobes, here there is a faint IR source that is shifted towards the west lobe, but that's ok - so this will be the host galaxy of the radio signal.
