Very strong Radio and red bits

    Not a 100% sure this is the right galaxy from several nearby but this is one of the more intense sources I can recall coming across, it even seems to have a halo of artifacts around it. But it also has red bits sticking out of it?

    Looking in Aladin lead me to this http://simbad.u-strasbg.fr/simbad/sim-id?Ident=PMN+J0210%2B0203&NbIdent=1 Aladin shows this, which I presume is also the strong Radio source in FIRST, in two slightly different locations near the galaxy I've posted above, but one is in the red material so are those red bits actually a galaxy in and of themselves?

    Hi @Ptd - this is very interesting. It looks like a higher redshift version of a green DRAGN. How many of these have you or anyone found?

    Hi @42jkb

    I can't immediately recall seeing anything else quite like this, I've seen a few compacts this strong I think, but can't remember such red sticky out bits, are they sticking out of the galaxy or are they a separate entity?

    If I see any more how would you like them hashtagged?

    'Red outflow' zph 0.335±0.055 SDSS J021054.06+020304.9 is not, I think (sadly), the host:

    Rather, it's likely zph 0.347±0.090 SDSS J021053.54+020302.9:

    @Ptd - yes a hashtag would be great, use #outflow as that way we can collect red, green, blue, white, etc. outflows. these outflows are indeed part of the host galaxy.

    @jeantate - yes it doesn't look like the host. However, they are close in redshift and maybe the radio has passes through the other galaxy causing the red outflow. Just a thought. Definitely requires followup.
