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…
