Unified Supernova Catalog Delivers Sharpest Dark Energy Constraints on Record

techtimes.com · 5dShare

Dark energy cosmological constant constraints hit record precision as the Unite supernova catalog, combining 2,884 Type Ia supernovae from 30 years of surveys through one unified pipeline, yields a 3.1-sigma frequentist preference for dynamical dark energy and a Figure of Merit 30% sharper than any prior analysis.
