Analysis of ~100 JWST LRDs finds redder, compact UV emission with Fe II/Mg II ~8-10 and correlations suggesting central red continuum (β_UV~0) beyond host galaxy contribution.
X-ray non-detection of little red dots requires both Compton-thick gas columns (~1e25 cm^-2) and intrinsically weak X-ray emission with bolometric correction k_bol,X ≳ 30.
Application of the Attenuation-Free Model to JWST super-early galaxies yields massive halos with moderate efficiencies and supports an evolutionary sequence from dust-reddened to UV-clear phases driven by outflows.
A review of theoretical models for the first stars and observational strategies including JWST searches, near-field studies, and lensing, noting growing candidates and narrowing parameter space.
