fainter than expected

THESIS Main (won): an accelerating universe driven by dark energy, from Type Ia supernovae (Riess et al. 1998, Perlmutter et al. 1999; Nobel 2011, shared with Schmidt) (LIT). Ghost (lost): the decelerating matter-only (Einstein–de Sitter) universe expected before 1998. COMPUTEDLuminosity distance by numerical integration. A supernova at z = 0.5 is about 0.40 mag fainter in flat ΛCDM (Ω_m 0.3, Ω_Λ 0.7) than in Einstein–de Sitter. The integrator is checked against the exact Einstein–de Sitter formula.
