ARG00011tc, Wat, host disk galaxy?

  • ChrisMolloy by ChrisMolloy

    Here's ARG00011tc, which appears to be a #Wat. The contour overlay below is positioned on SDSS J073849.51+415907.4, which is SSW of the ARG co-ordinates listed left. This ARG field is cross referenced in the following post: ARG00011tc field: apparent host has weird spiral shape?

    The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
    thread.     First in red.

    The host for the emission appears to be SDSS J073849.51+415907.4, which has a z_sp=0.179 +/-0.00003. This object has an apparent radio reference in SIMBAD, and an ALLWISE reference, ALLWISE J073849.56+415907.6. This galaxy also appears to be #green and have #red-outflows. It also is in a #cluster environment, maybe interacting with SDSS J073849.89+415921.8, which is NNE of the galaxy, and could possibly be an #SDRAGN candidate.

    In terms of this galaxy being an #SDRAGN candidate, it has a fracDev_g, _r, of 1 and 1; and an expAB_g of 0.838 and expAB_r of 0.862 respectively. For c, the inverse concentration index, it has a figure of 0.379 for the g band and 0.330 for the r band. Possibly hard to determine whether this is a disk galaxy or not, although there does seem to be some sort of spiral structure, and also, the white foreground star to the east of the galaxy does seem to obscure parts of this object. Others may have a view on this, although the GZ2 classification cites this galaxy as being more #elliptical and #smooth, than #disk like and #spiral.

    It doesn't appear this ARG field has been imaged in VLASS as yet.

    As always, comments, suggestions, welcome.
