“JWST /NIRCam counterpart from the COSMOS-Web survey to a far-infrared SCUBA-2 and ALMA source, AzTECC71”
“undetected in NIRCam/F150W and F115W and fainter in F444W than other sub-millimeter galaxies identified in COSMOS-Web by 2 − 4 magnitudes.”
“detections in F277W, F444W and the far-IR including ALMA Band 6,” -> zphot = 5.7, massive and IR luminous.
“he number densities of these sources and their contributions to the cosmic star-formation rate density at z > 3 have been largely unconstrained, which may substantially alter our view of early star formation based on UV-bright Lyman-break galaxies”
“assessing the prevalance of dust-obscured star-formation at early times as well as the evolutionary role occupied by dusty galaxies.”
“number densities of dusty star-forming and quiescent galaxies broadly agree with the former as progenitors of the latter (e.g., Toft et al. 2014; Valentino et al. 2020)”
