Abstract:
    We extend color-magnitude relations for moderate-luminosity X-ray
    active galactic nucleus (AGN) hosts and non-AGN galaxies through the
    galaxy formation epoch (z∼1-4) in the Chandra Deep Field-North and
    Chandra Deep Field-South (CDF-N and CDF-S, respectively; jointly CDFs)
    surveys. This study was enabled by the deepest available X-ray data
    from the 2Ms CDF surveys as well as complementary ultradeep
    multiwavelength data in these regions. We utilized analyses of
    color-magnitude diagrams (CMDs) to assess the role of
    moderate-luminosity AGNs in galaxy evolution.

Note (1): Spectroscopic redshift (with a plus sign in f_z) or photometric
          redshift.
Note (2): Regardless of whether there is corresponding rest-frame coverage
          of a source.
Note (3): This flag shows which stellar-mass estimate is adopted as the final
          estimate for a source as follows: 
      1 = logMB
      2 = logMV
      3 = logMR
      4 = logMI
      5 = logMJ
      6 = logMH
      7 = logMK
