Abstract
Selecting the first galaxies at z > 7 − 10 from JWST surveys is complicated by z 7–10 Lyman-break galaxies (LBGs). Dust-obscured 3 − 1.5 and z > 4. While there are some redshifts ( z ∼ 3.75) where our stack is more degenerate with the photometry of z > 10 LBGs at λ _rest ∼ 0.3–0.8 μ m , redder filter coverage beyond λ _obs > 3.5 μ m and far-IR/submillimeter follow-up may be useful for breaking the degeneracy and making a crucial separation between two fairly unconstrained populations, dust-obscured galaxies at z ∼ 3–6 and LBGs at z > 10.
