ARG0002h1x - is the doublelobe host a disk galaxy?

  • JeanTate by JeanTate

    SDSS J085841.97+180358.5, z_ph 0.196±0.0307/0.220±0.0695, isn't much to look at (the 'red and noisy sky' is due to a nearby bright star, which is also responsible for the WISE diffspike):

    It's a bit too pointy to be a boring elliptical, though only some quantitative tests will confirm that's it's more likely a disk galaxy. However, there's little doubt that it's the host of a nice doublelobe:

    Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) contours derived from the FITS file produced using SkyView with Python code described in this RGZ Talk thread. Image center (J2000.0) is the galaxy SDSS J085841.97+180358.5; "z_ph" its SDSS photometric redshift.

    Core no longer active; single lobe on one side; rather longer, more broken up on on the other:
