TL;DR
This paper explores how sterile neutrinos produced in strong magnetic fields via URCA processes could explain the high velocities observed in pulsars, using a model fitted to experimental data.
Contribution
It introduces a model linking sterile neutrino emissions in Landau levels to pulsar kicks, based on fits to MiniBooNE and LSND data.
Findings
Sterile neutrino emissivity can produce significant pulsar kicks.
Landau level effects increase asymmetry in neutrino emission.
Model aligns with observed pulsar velocities.
Abstract
We use a model with two sterile neutrinos obtained by fits to the MiniBoone and LSND experiments. Using formulations with neutrinos created by URCA Processes in a strong magnetic field, so the lowest Landau level has a sizable probability, we find that with known paramenters the assymetric sterile neutrino emissivity might account for large pulsar kicks.
