摘要: Weak lensing of high-redshift Type Ia supernovae induces an external dispersion in their observed standard candle brightnesses, comparable magnitude to the intrinsic for redshifts z > 1. The same matter fluctuations responsible magnification distant also generate shear images background galaxies. We investigate possibility using maps constructed from galaxies surrounding as a means correcting lensing-induced dispersion. find that considerable fraction derives subarcminute scales, which are not probed by smoothed on arcminute scales. thus weak-lensing will be only limited value reducing supernovae.
