ARG0001c1m, multiple emissions and hosts

  • ChrisMolloy by ChrisMolloy

    Here's ARG0001c1m, which has a number of emissions, including a possible #triple and #doublelobe, and a couple of #compact lobes.

    thread.     First in red.

    The host for the centre emission, which appears to be a #triple, seems to be SDSS J124826.97+364335.2. This galaxy has a z_ph=0.601 ± 0.0556, and radio references in NED and SIMBAD. Regarding the latter references, these are centred on different parts of the emission. This galaxy also has an ALLWISE reference, ALLWISE J124826.99+364335.1.

    SW of the centre #triple there is a #diffuse #compact lobe which is positioned on SDSS J124825.96+364318.3. This object has a z_ph=0.693 ± 0.0454, recorded First flux emission, and radio references in NED and SIMBAD, with the latter reference positioned slightly west of the galaxy. There is also an ALLWISE reference, ALLWISE J124825.98+364318.3.

    Further SW there is a lobe which could be related to either SDSS J124825.96+364318.3 or SDSS J124826.97+364335.2. This emission is #no-optical, #noir, although in the First contour overlay above, this lobe does seem related to either of these hosts and their emissions.

    Furtherest south is a #compact lobe. There is a radio reference in NED for SDSS J124827.73+364248.2, which is listed as a star, and is east of this emission. However, there is a SIMBAD reference, which is positioned in the centre of the lobe, and an ALLWISE reference slightly west of the centre of the lobe, ALLWISE J124827.04+364243.3.

    Centre west and WNW (especially in VLASS), there is an emission which could be a #bent or #s-shaped, #doublelobe. A host could be SDSS J124821.80+364336.2, which has a z_sp=0.606 +/-0.00012. This object has radio references in NED and SIMBAD and an ALLWISE reference, ALLWISE J124821.71+364336.5. Regarding the SIMBAD reference, this is slightly WSW of the galaxy.

    Here's a VLASS contour overlay of the ARG field. The contours, especially the #diffuse #compact SW of the central emission, and possible #doublelobe to the WNW, seem to be more defined,

    As always, comments, suggestions, welcome.

    Very nice! 😃

    The main source, which seems to be the NE lobe of the main host, would also be an #overlap ... a separate host ~in the center (dimple in VLASS contours ~encloses this), which may be a #triple.
