J/ApJ/704/548    Photometric properties of galaxies at z=4-6   (Overzier+, 2009)

Stellar masses of Lyman break galaxies, Lyα emitters, and radio galaxies in overdense regions at z = 4-6. Overzier R.A., Shu X., Zheng W., Rettura A., Zirm A., Bouwens R.J., Ford H., Illingworth G.D., Miley G.K., Venemans B., White R.L. <Astrophys. J., 704, 548-563 (2009)> =2009ApJ...704..548O
ADC_Keywords: Galaxies, photometry ; Photometry, infrared ; Radio sources Keywords: galaxies: high-redshift - galaxies: stellar content - large-scale structure of universe - quasars: individual (TNJ1338-1942, TNJ0924-2201, SDSSJ0836+0054, SDSSJ1030+0524) Abstract: We present new information on galaxies in the vicinity of luminous radio galaxies (RGs) and quasars at z∼4, 5, and 6. These fields were previously found to contain overdensities of Lyman Break Galaxies (LBGs) or spectroscopic Lyα emitters (LAEs), which were interpreted as evidence for clusters-in-formation ("protoclusters"). We use Hubble Space Telescope and Spitzer data to infer stellar masses from stellar synthesis models calibrated against the Millennium Run simulations, and contrast our results with large samples of LBGs in more average environments as probed by the Great Observatories Origins Deep Survey (GOODS). Description: In this paper we will derive stellar masses, as inferred from the rest-frame optical fluxes, for a sample of LBGs, LAEs, and RGs in two protoclusters: "TN1338" at z∼4.1 and "TN0924" at z∼5.2. For completeness, we also present a small sample of i-dropouts near two quasars (SDSSJ0836+0054 and SDSSJ1030+0524) at z∼6 studied by Stiavelli et al. (2005ApJ...622L...1S) and Zheng et al.

Note (1): From Overzier et al. (2008, Cat. J/ApJ/673/143; <[OBC2008] NNNN> in Simbad for table 2 or <[VRM2007] J1338.LAENN> for table 3; see also Venemans et al., 2007, Cat. J/A+A/461/823). Note (2): Flag as follows: e = Lyα Emitters. f = The 3.6um measurement most probably includes a large contribution from the Hα emission line halo of the radio galaxy. Applying a correction for Hα yields a 3.6um continuum magnitude of 21.2±0.1 (see Section 3.1 for details). This is the value plotted in Figures 5 and 6.
