Forecast for growth-rate measurement using peculiar velocities from LSST supernovae
Damiano Rosselli, Bastien Carreres, Corentin Ravoux +8
In this work, we investigate the feasibility of measuring the cosmic growth-rate parameter, , using peculiar velocities (PVs) derived from Type Ia supernovae (SNe Ia) in the…
