ARG0000rvf: #bhgroup, rich cluster but BCG is not a radio source!

  • JeanTate by JeanTate

    There are three radio sources, one a very nice asymmetric #corejet.

    However, the obvious BCG (brightest cluster galaxy) is not a radio source! 😮

    Here's the compact, rich cluster, centered on SDSS J164022.01+464246.0, the host of the #corejet:

    As I have found in many other compact clusters of galaxies, there seems to be some purple and green 'fluff' (blobs) around.

    For example, zph 0.40 SDSS J164021.99+464312.5:

    And zph 0.35 SDSS J164021.61+464325.0:

    As these really more distant, unrelated background galaxies?

    What do you think?
