Kavli Affiliate: Richard Kessler | First 5 Authors: Ayan Mitra, Richard Kessler, Surhud More, Renee Hlozek, | Summary: We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using only the "zspec" subset with spectroscopic redshifts from the host or SN. We […]
