Prospective Constraints on Neutrino Masses from a Core-Collapse Supernova
read the original abstract
We discuss the prospects for improved upper limits on neutrino masses that may be provided by a core-collapse supernova explosion in our galaxy, if it exhibits time variations in the neutrino emissions on the scale of a few milliseconds as suggested by recent two-dimensional simulations. Analyzing simulations of such neutrino emissions using the wavelet technique adopted in [1], we find that an upper limit m_nu ~ 0.14 eV could be established at the 95% confidence level if the time variations in emissions were to be preserved during neutrino propagation to the Earth.

Time-of-Flight Constraints on Neutrino Millicharge from Supernova Neutrinos in Galactic Magnetic Fields
Reinterprets SN1987A and projected Galactic supernova time-of-flight data as millicharge bounds from 10^{-17} e down to low 10^{-19} e using line-of-sight magnetic delay kernels.

Time-of-Flight Constraints on Neutrino Millicharge from Supernova Neutrinos in Galactic Magnetic Fields
Reinterpreting SN1987A and future galactic supernova time-of-flight data yields neutrino millicharge bounds from 10^{-17} e down to 10^{-19} e or better using a line-of-sight magnetic delay kernel.
