Abstract:
    We present a new measurement of the integrated stellar mass per
    comoving volume at redshift 5 determined via spectral energy fitting
    drawn from a sample of 214 photometrically selected galaxies with
    z'_850LP_<26.5 in the southern GOODS field. Following recent
    procedures introduced by Eyles et al. (2007MNRAS.374..910E), we
    estimate stellar masses for various subsamples for which reliable and
    unconfused Spitzer IRAC detections are available. A spectroscopic
    sample of 14 of the most luminous sources with z{bar}=4.92 provides a
    firm lower limit to the stellar mass density of
    1x10^6^M_{sun}_/Mpc^3^.
    We then consider a larger sample whose photometric redshifts in the
    publicly available GOODS-MUSIC catalog lie in the range 4.4<z<5.6.
