It's not ${\sigma }_8$ : constraining the non-linear matter power spectrum with the Dark Energy Survey Year-5 supernova sample

Paul Shah, T. M. Davis, M. Vincenzi +58

The weak gravitational lensing magnification of Type Ia supernovae (SNe Ia) is sensitive to the matter power spectrum on scales $k>1h$ Mpc${}^{-1}$, making it unwise to interpret SN…
