The Dark Energy Survey : Detection of weak lensing magnification of supernovae and constraints on dark matter haloes
P. Shah, T. M. Davis, D. Bacon +62
The residuals of the distance moduli of Type Ia supernovae (SN Ia) relative to a Hubble diagram fit contain information about the inhomogeneity of the universe, due to weak lensing…
