Neutrino mass constraint by the lensing observation on m-z relation of Supernovae |
|
Abstract |
We investigate the possibility to have interesting constraints on nuetrino mass and dark energy property by the lensing effect of m-z relation of type Ia supernovae . With a fitting formula of nonlinear matter power spectrum we find that it is possible to obtain the upper limit of the order of 0.2 eV and more severe constraint on the equation of state parameter of dark energy for future optical imaging survey with LSST and WFIRST. |
