RGZ sources with Red Outflows
-
by 42jkb scientist, admin
Please post to here if you see a RGZ source with a red outflow. These appear to be closely related to the green galaxies but at higher redshifts.

I started a Collection of these, High-z "green". At the moment it has just one object in it, zph 0.643±0.072 SDSS J155115.98+151727.8 (ARG field ARG0002nfs):
I've certainly come across several more ... just didn't collect them 😦

Interesting.
I am particularly looking at the red outflow. This one you have shown doesn't appear to have an outflow - or it is just my computer screen and eyesight.

Here's what the zph 0.335±0.055 host, SDSS J021054.06+020304.9, looks like:
There's quite a lot of 'red fluff' nearby ...

Thanks JeanTate for the figure. This indeed shows what I am looking for -- that red fluff.

This kind of objects can be of interest here? I know that isn't exactly "outflows", but show similar colours (may be the flow is in hide perspective) and [OIII] emission.

@sisifolibre - this may be, will have to look into this one.
@Ptd - this one looks promising.
Thanks for the objects! Let me know if you find anymore.

In ARG0003qsk, the host seems to be zph 0.394±0.087 SDSS J003510.58+013345.1, which seems to have red #outflow:

Found this SDSS J093638.53+634703.4, but I suspect the radio lobe near it belongs to SDSS J093637.33+634711.6 which has a totally different Z so suspect just chance alignment.
If we come across these, without any directly associated Radio Lobe/s do you want them posted here? Please advise, MT Ptd.

From a distance it looks green.But zoom in and
It has red bits as well

Any one that has a radio source nearby in the image (not necessarily redshift space) I would like to see. The radio emitting structure can expand to large distances away from the host galaxy. If there are other galaxies nearby, the radio source can be affected them. This provides clues to how radio galaxies can influence their environments.

Does this constitute as one? The red outflows are more SW of ARG0001wiy, SDSS J130623.30+270246.6. Appears to be group or possible merger, with Radio galaxy in the centre, and all at ~ z=0.3.

If real, the red stuff is ~orthogonal to the radio jets.

just my 2-cents but we should remember to try not to infer too much from very low signal-to-noise images especially for the sources which reside beyond z~0.2. The last few candidates appear to be very close to the background level...

by JeanTate in response to ivywong's comment.
Yes indeed.
What would advise re reporting on what we come across?
Myself (my $0.02's worth), I err on the side of having more false positives (red stuff that is really just noise) than false negatives (seeing red stuff but not reporting it; yet it's actually a red outflow): it can be tedious wading through lots of false positives, but you can never find any false negatives! 😮

Hi @ivywong Many thanks for feedback, have noticed, once I started looking for it, multi coloured mottling around quite a few bright objects in SDSS, red and green usually, and had begun to question if that was real or not. From your feedback I should only post if the red is noticeably stronger than the green?

by ivywong scientist, admin
The "mottling" is really the background noise but if you do see something that clearly stands out from the background mottling by a factor of 2-3, it's definitely worth noting this down. Thanks for asking 😃

In , apparent zph 0.237±0.114 host SDSS J143233.49+034505.1 appears to have a pair of red outflows:
In ARG0000i4e, apparent zph 0.323±0.202 host SDSS J125825.39+514226.0 seems to have both a green and a red outflow:
In ARG00028m3, apparent zsp 0.422 host SDSS J122939.80+215816.9 appears to have a 'red ring' outflow:

It's hard to say what is a real outflow, background galaxy or just noise, I think that there are a lots of possible candidates for this kind of subjects. I have this little collection with my best candidates, if anyone with better skills want to take a look and select some of them for post it here.

Thanks sisifolibre! I'll have a look through and see where we can go from there.

Frankly, I think it is a green candidate rather than red outflow

In ARG00023sl, zsp 0.345 host SDSS J111419.47+235525.9 has a nice red #outflow, almost a halo:

In ARG0001pfe, host zph 0.415±0.204 SDSS J080746.12+302148.2 has a prominent red #outflow to its NE and/or N ... or maybe it's a galaxy or two, perhaps not even associated with the host?

Great candidates.

by 42jkb scientist, admin in response to Ptd's comment.
Sorry for the delayed respoonse @Ptd. Yes, if you do see ones with no radio it will be interesting to have. One question is why are there ones with radio and ones without? Are these the same type of host galaxy? etc.

by 42jkb scientist, admin
I have now catalogued all of these up to here. There are 20 candidates from this talk thread.
Many thanks! Will keep you posted.
