ARG0003fke, hybrid, hosts?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0003fke, which appears to exhibit a #hybrid morphology, extending #overedge, ESE. This emission is cross referenced as ARG0003fm2, and ARG0003fkr.

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

    A possible host for this emission appears to be SDSS J000707.18+053609.4, which has a z_ph=0.216 ± 0.0258. This object has an ALLWISE reference, ALLWISE J000707.12+053609.6, and is possibly a #disk galaxy, and slightly #green.

    As for this object being a #disk galaxy and an #SDRAGN candidate, it has a fracDev_g, _r, of 0.789, and 0.837; and an expAB_g of 0.401 and expAB_r of 0.465 respectively. For c, the inverse concentration index, it has a figure of 0.405 for the g band and 0.418 for the r band. On the above figures it's hard to ascertain whether this is a disk galaxy or not.

    As noted left in the ARG comments field, there is the possibility of the galaxies to the S and SE of SDSS J000707.18+053609.4 being hosts.

    To the S is SDSS J000707.09+053604.6, which has a z_ph=0.290 ± 0.0263. This object could possibly be a #disk galaxy also.

    As for this object being a #disk galaxy and an #SDRAGN candidate, it has a fracDev_g, _r, of 0.837 and 0.925; and an expAB_g of 0.149 and expAB_r of 0.317 respectively. For c, the inverse concentration index, it has a figure of 0.328 for the g band and 0.306 for the r band. Again, it's hard to discern whether this is a #disk galaxy or not.

    And to the SE is SDSS J000707.42+053605.2, which has a z_ph=0.218 ± 0.0300. This object appears to be slightly #green also.

    In terms of radio references for the host of this emission, excluding the ALLWISE reference mentioned above, there are radio references in NED, and Simbad. The NED citation doesn't reference a specific galaxy in particular, and regarding the Simbad reference, this seems to be centred slight to the W of these three objects.

    Finally SDSS J000707.18+053609.4 and SDSS J000707.42+053605.2, could be a #g-pair, although there doesn't seem to be any references noting this in NED or Simbad.

    As always, comments, suggestions, welcome.
