Neutrino masses from failed supernovae

Can we measure the mass of neutrinos with a multi-messenger detection of a failed supernova?

Neutrinos being massive gives them a slight delay, which looks like this:

In this repo, one can find estimates and mock data towards this purpose. The file overview.md provides an overview.

Scripts

Neutrinos

  • flux_estimate.py: define a neutrino energy distribution, generate energies stochastically
  • inference.py: generate neutrinos in time and energy, delay them in time
  • inference_plots.py: plot the probabilities and reconstructed masses
  • delays.py: plot the delays as a function of energy and mass

Gravitational waves

  • gw_mock.py: add signal to simulated noise, whiten, bandpass, plot
  • QNM_estimates.py: very simple frequency estimates for BH QNM
  • gw_sounds.py: save the SN waveforms as audio files
  • gw_noise.py: unused, experiment in generating noise manually
