Overview: Beacon (Bias-free Extragalactic Analysis for Cosmic Origins with NIRCam) is a JWST pure-parallel imaging survey awarded 600 hours during Cycle 2 to address fundamental questions in extragalactic astronomy: What are the properties of the first galaxies? When did they form? How did galaxies acquire mass, evolve in structure, and quench star formation? Beacon will build a large, unbiased sample of the universe across 100 independent sightlines (~0.3 sq deg total area), minimizing cosmic variance to achieve a comprehensive census of early galaxies. Our NIRCam imaging spans 8+ bands, providing uninterrupted spectral coverage from 0.8 to 5 microns. This allows for robust photometric redshift determination and physical property analysis of sources at redshifts z ~ 2 to z > 10 through spectral energy distribution (SED) modeling.
