Improving the Determination of Supernova Cosmological Redshifts by Using Galaxy Groups
Erik R. Peterson, Bastien Carreres, Anthony Carr +9
At the low-redshift end () of the Hubble diagram with Type Ia Supernovae (SNe Ia), the contribution to Hubble residual scatter from peculiar velocities is of similar size t…
JWST Validates HST Distance Measurements: Selection of Supernova Subsample Explains Differences in JWST Estimates of Local H0
Adam G. Riess, Dan Scolnic, Gagandeep S. Anand +16
JWST provides new opportunities to cross-check the HST Cepheid/SNeIa distance ladder, which yields the most precise local measure of H0. We analyze early JWST subsamples (~1/4 of t…
WiFeS observations of nearby southern Type Ia supernova host galaxies
Anthony Carr, Tamara M. Davis, Ryan Camilleri +3
We present high-resolution observations of nearby () galaxies that have hosted Type Ia supernovae to measure systemic spectroscopic redshifts using the Wide Field Sp…
