Abstract:
    We present the results of a systematic search for candidate quiescent
    galaxies in the distant universe in 11 JWST fields with publicly
    available observations collected during the first 3 months of
    operations and covering an effective sky area of ~145arcmin^2^. We
    homogeneously reduce the new JWST data and combine them with existing
    observations from the Hubble Space Telescope. We select a robust
    sample of ~80 candidate quiescent and quenching galaxies at 3<z<5
    using two methods: (1) based on their rest-frame UVJ colors, and (2) a
    novel quantitative approach based on Gaussian mixture modeling of the
    near-UV-U, U-V, and V-J rest-frame color space, which is more
    sensitive to recently quenched objects. We measure comoving number
    densities of massive (M_*_>=10^10.6^M_{sun}_) quiescent galaxies
    consistent with previous estimates relying on ground-based
    observations, after homogenizing the results in the literature with
    our mass and redshift intervals. However, we find significant
    field-to-field variations of the number densities up to a factor of
    2-3, highlighting the effect of cosmic variance and suggesting the
    presence of overdensities of red quiescent galaxies at z>3, as could
    be expected for highly clustered massive systems. Importantly, JWST
    enables the robust identification of quenching/quiescent galaxy
    candidates at lower masses and higher redshifts than before,
    challenging standard formation scenarios.

Description:
    We homogeneously process the publicly available JWST imaging obtained
    with the NIRCam, NIRISS, and MIRI instruments in 11 fields targeted
    during the first 3 months of operations. We further incorporate the
    available optical and near-infrared data available in the Complete
    Hubble Archive for Galaxy Evolution (CHArGE;
    Kokorev+ 2022ApJS..263...38K). See Section 2.1. We provide further
    details about the individual fields in Appendix A.
