Extended Data Fig. 7: H − [4.5] colour versus stellar mass for massive galaxies at 3.5 < z < 6.5.
From: A dominant population of optically invisible massive galaxies in the early Universe
Galaxies selected from the ZFOURGE catalogue (left, 3.5 < z < 4.5; right, 4.5 < z < 6.5) with HST/F160W detections (H < 27 mag) are shown in green while the H-dropouts selected in the same fields are shown in red. The H − [4.5] colour of the H-dropouts are shown by their lower limit assuming H > 26.5 mag (5σ). Quiescent and star-forming galaxies are shown by open and filled circles, respectively. Quiescent H-dropouts are defined as those undetected with ALMA while quiescent ZFOURGE galaxies are defined by their sSFR (based on SED fitting) with sSFR < 0.3 Gyr−1 and no MIPS 24-μm detections8.
