ARG0000tx0, doublelobe, triple, SDRAGN candidate?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0000tx0, which appears to be a #doublelobe or possibly a #triple.

    thread.

    The host for the emission could be SDSS J134900.13+454256.5, which has a z_ph=0.345 ± 0.0706, and an ALLWISE reference, ALLWISE J134900.12+454256.6. It also appears to be slightly #red and #green.

    As per the classification comments left, and whether SDSS J134900.13+454256.5 is a spiral or disk galaxy, it has a fracDev_g, _r, of 0 and 0.503, and an expAB_g of 0.307 and expAB_r of 0.288 respectively. For c, the inverse concentration index, it has a figure of 0.578 for the g band and 0.360 for the r band. On the above parameters, there is the possibility that this could be a disk galaxy, but definitively, this is hard to say. Further, there is the question of whether this galaxy actually is the host of the emission. Others may wish to comment more on this.

    An alternative host could be SDSS J134901.54+454259.9, a faint galaxy, which is more centred near the middle lobe, has a z_ph=0.406 ± 0.1053, and an NVSS reference in NED.
