The physics of the supernova may provide a clue of the cosmological dark matter. In the absence of new physics, the supernova calculations do not explain the observed velocities of pulsars. However, if there exists a singlet fermion with mass in the 1-20 keV range and a small mixing with neutrinos, this particle could be emitted asymmetrically from a cooling neutron star in the event of a supernova explosion. The asymmetry could explain the long-standing puzzle of pulsar velocities. The same…

Evolution of Astrophysics: Stars, Galaxies, Dark Matter, and Particle Acceleration
Starting about a hundred years ago we review some of the most exciting astrophysics science developments in Stars, Galaxies, Dark Matter, and Particle Acceleration, (i) the discovery of Gamma-ray


Pulsar kicks from a dark-matter sterile neutrino
We show that a sterile neutrino with mass in the 1-20 keV range and a small mixing with the electron neutrino can simultaneously explain the origin of the pulsar motions and the dark matter in the
Bursts of Gravitational Waves Driven by Neutrino Oscillations
Active-to-sterile neutrino oscillations and nonspherical distortion of the resonance surface may trigger asymmetric emission of sterile neutrinos during the core bounce of a supernova collapse. The
Pulsar Velocities and Neutrino Oscillations.
The connection between the pulsar velocities and neutrino oscillations results in a prediction for the neutrinos mass of approximately 100 eV.
Pulsar recoil by large-scale anisotropies in supernova explosions.
It is shown that low-mode (l=1,2) convection can develop from random seed perturbations behind the shock, requiring the core luminosity to vary slowly with time, in contrast to the burstlike exponential decay assumed in previous work.
Gravitational waves from a pulsar kick caused by neutrino conversions
It has been suggested that the observed pulsar velocities are caused by an asymmetric neutrino emission from a hot neutron star during the first seconds after the supernova collapse. We calculate the
Direct Detection of Warm Dark Matter in the X-Ray
We point out a serendipitous link between warm dark matter (WDM) models for structure formation on the one hand and the high-sensitivity energy range (1-10 keV) for X-ray photon detection on the
Neutrino transport: no asymmetry in equilibrium
Abstract A small asymmetry in the flux of neutrinos emitted by a hot newly-born neutron star could explain the observed motions of pulsars. However, even in the presence of parity-violating processes
Neutrino oscillation mechanism for pulsar kicks reexamined
Anisotropic neutrino emission during the neutron star formation can be the origin of the observed proper motions of pulsars. We derive a general expression for the momentum asymmetry in terms of the
Neutron Star Kicks from Asymmetric Collapse
Many neutron stars are observed to be moving with spatial velocities, in excess of 500 km s-1. A number of mechanisms have been proposed to give neutron stars these high velocities. One of the
No pulsar kicks from deformed neutrinospheres
In a supernova core, magnetic fields cause a directional variation of the neutrino refractive index so that resonant flavor oscillations would lead to a deformation of the "neutrinosphere" for, say,
