ARG0003bq9, hosts? morphology?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0003bq9, which appears to either be a #bent #triple; a #doublelobe centre and east, with an extended #compact to the WSW; or three separate #compact lobes.

    First in red, Wise band 1 lime green.

    There are radio references in NED and possibly Simbad for SDSS J161201.81+065630.1, a very faint galaxy, with an SDSS DR9 z_ph=0.341 +/-0.093. This object seems to be centred on the W edge of the far east lobe, almost in-between the centre and east lobe.

    There is an ALLWISE reference for the centre First emission, ALLWISE J161201.25+065625.2, with the corresponding Wise Band 1 lobe visible in the above contour image at this location. There doesn't appear to be an SDSS photometric object at this position.

    As for the extended #compact lobe to the WSW, there is an ALLWISE reference, ALLWISE J161200.16+065616.7, which is centred on SDSS J161200.17+065616.5. This appears to be a #disk galaxy, with a z_ph=0.428 ± 0.0896. The corresponding Wise Band 1 lobe is visible in the above contour image on this object. The tail end of the First emission is centred on SDSS J161200.17+065616.5.

    It is hard to discern definitively what the radio morphology definitely is for the emissions in this ARG field. Possibly three separate #compact lobes, or maybe a #doublelobe centre and east, and an #extended #compact lobe to the WSW. If it is three separate #compact lobes, then the lobe to the east could maybe be an #ifrs emission. Finally, it doesn't appear on the above analysis, that this emission is a #triple.

    As always, comments, suggestions, welcome.
