Wonderful z~0.65 rich galaxy cluster!

• by JeanTate

  Check it out (centered on SDSS J012412.94+055545.5):

  

  So many giant ellipticals, so few radio sources ...

  nice. do you know if this is a known cluster?

  I wonder if there is a way that RGZ can help to identify clusters.....

  The cross-ID with Wen et al (2012)'s SDSS cluster catalogue as posted by @Dolorous_Edd is a good start for low-z clusters but optical IDs are not so useful for our RGZ sources at higher redshifts....

  Perhaps future all-sky X-ray or S-Z catalogues can help?

  In terms of RGZ

  It can, the best give away of a cluster is a presence of the WAT and NAT radio galaxies

  That is true about the WAT and NAT galaxies -- we can catalogue these and cross match with known cluster catalogues. I'm on holiday and my brain is going a mile a minute thinking about this.
