Radio Galaxy Zoo Talk

ARG0003bqf centred on a string of pearls!

  • ChrisMolloy by ChrisMolloy

    Here is ARG0003bqf. Unsure as to how to describe the morphology with the exception that it's very extended, and possibly has one or more emissions, extending over the four galaxies in this group and predominantly to the SW.

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

    The host appears to be SDSS J025625.91+065626.5, which has a z_sp=0.116700 +/- 0.000300 per NED, and is referenced in the following paper, The Radio Galaxy Populations of Nearby Northern Abell Clusters.

    NVSS image of the diffused radio halo is quite large. Neat alignment 😃

    Cool! 😃

    I wonder if there is, in fact, more than one host? For example, I think the galaxy at the SW end of the string, zph 0.120±0.012 SDSS J025625.37+065622.4, could be a host:

    @ivywong:

    What does that indicate, given that the z is ~0.12?

    This means that FIRST may have resolved out some of the diffused radio emission from this subject. The radio emission from other host galaxies may be of lower surface brightness than the main radio galaxy in this image.
