Potential distortions in neutrino burst timing and brightness due to lensing

A proposed method to verify gravitational lensing effects in neutrino data

Abstract

Supernova neutrino bursts have been observed from extragalactic distances. This note addresses the question of how gravitational lensing could distort the information in the burst. We apply the gravitational lens hypothesis to try to understand the time and brightness structure of the SN1987A neutrino observations. Estimates of a possible lensing mass and alignment are made. These estimates suggest a path to verification.
