Gamma-Ray Bursts from High Velocity Neutron Stars

We investigate the viability of the Galactic halo model of $\gamma$-ray bursts by calculating the spatial distribution of neutron stars born with high velocities in the Galactic disk, and comparing the resulting brightness and angular distribution with the BATSE data. We find that the Galactic halo model can reproduce the BATSE peak flux and angular distribution data for neutron star kick velocities $\text{simgreat}800$~\kms, source turn-on ages $\simgreat 10$Myrs,andsamplingdepths$100{\rm~kpc}\simless d_{max} \simless 400$~kpc.
