However, due to the very limited photometry for individual galaxies, the true nature of these so-called HST-dark galaxies has remained elusive. Here, we present the first sample of such galaxies observed with very deep, high-resolution NIRCam imaging from the Early Release Science programme CEERS. 30 HST-dark sources are selected based on their red colours across 1.6-4.4 {mu}m. Their physical properties are derived from 12-band multiwavelength photometry, including ancillary HST imaging. We find that these galaxies are generally heavily dust-obscured (A_V_ ~2 mag), massive (logM/M_{sun}_) ~10), star-forming sources at z ~ 2-8 with an observed surface density of ~0.8 arcmin^-2^. This suggests that an important fraction of massive galaxies may have been missing from our cosmic census at z > 3 all the way into the Epoch of Reionization. The HST-dark sources lie on the main sequence of galaxies and add an obscured star formation rate density of 3.2^+1.8^_-1.3_ * 10^-3^M_{sun}_/yr/Mpc^3^ at z ~ 7, showing likely presence of dust in the Epoch of Reionization. Our analysis shows the unique power of JWST to reveal this previously missing galaxy population and to provide a more complete census of galaxies at z = 2-8 based on rest-frame optical imaging.2023MNRAS.522..449Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/522/449CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/496/695 : Timing the earliest quenching events (Carnall+, 2020)J/ApJ/923/215 : MORA: ALMA 2mm survey (Casey+, 2021)J/ApJ/876/135 : 33 Optically faint galaxies (Alcalde Pampliega+, 2019)J/ApJ/806/110 : ALESS survey: SMGs in the ECDF-S data (da Cunha+, 2015)J/ApJ/788/125 : An ALMA survey of ECDFS submillimeter galaxiesJ/ApJS/218/33 : Spitzer-CANDELS catalog within 5 deep fields (Ashby+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/522/449https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/522/449http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/522/449https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/522/449https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/522/449http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/522/449GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/522/449/tablea1 (HST-dark galaxy and derived properties by BAGPIPES code on HST/JWST/Spitzer/IRAC data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/522/449/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/522/449/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/522/449/tablea1?GETtext/xml+votable180.050000true214.998403753.00462350.0055555555555555566/11425https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/522/449?format=asciiOpticalInfrareddefaultJ/MNRAS/522/449/tablea1HST-dark galaxy and derived properties by BAGPIPES code on HST/JWST/Spitzer/IRAC datarecnoRecord number assigned by the VizieR team.
