What to do ?

    I think there's a pair of jets in radio source, but couldn't find a galaxy in IR... what to do ?

    As the radio emission is rather weak, it's hard to say what's going on.

    I think this is a #triple, which is a central radio source (the "core") and two other radio sources on either side (these are called "lobes"). It's somewhat asymmetric: the W (right, astronomers reverse E and W!) lobe is closer (to the core) and brighter than the E one (which is detached); this is not at all unusual!

    The host - the galaxy from which the radio emission ultimately arises - is visible in the WISE IR image, but it is so faint that it's invisible in SDSS; here's its approximate position (note that lobes are almost never visible in IR or optical images):

    Hope this helps, and happy hunting! 😃
