Detecting neutrino transients with optical follow-up observations

A novel method is presented which will enhance the sensitivity of neutrino telescopes to identify transient sources such as Gamma-Ray Bursts (GRBs) and core-collapse Supernovae (SNe). Triggered by the detection of high energy neutrino events from lceCube or other large scale neutrino telescopes, an optical follow-up program will allow the identification of the transient neutrino source. We show that once the follow-tip program is implemented, the achievable sensitivity of IceCube to neutrinos from SNe and GRBs would increase by a factor of 2-3. The program can be realized with a small network of automated 1-2 m telescopes and has rather modest observing time requirements. (C) 2007 Elsevier B.V. All rights reserved.
