Effects of atmospheric electric fields on detection of ultrahigh-energy cosmic rays

Alexander Kusenko, Dmitry Semikoz

We show that atmospheric electric fields may affect the cosmic ray observations in several ways and may lead to an overestimation of the cosmic ray energies. The electric field in…

Pulsar kicks from neutrino oscillations

Alexander Kusenko

Neutrino oscillations in a core-collapse supernova may be responsible for the observed rapid motions of pulsars. Given the present bounds on the neutrino masses, the pulsar kicks r…

Neutrino oscillations, and the origin of pulsar velocities and dark matter

Alexander Kusenko

Neutrino oscillations in a core-collapse supernova may be responsible for the observed rapid motions of pulsars. Three-dimensional numerical calculations show that, in the absence…

Bounds on heavy sterile neutrinos revisited

Alexander Kusenko, Silvia Pascoli, Dmitry Semikoz

We revise the bounds on heavy sterile neutrinos, especially in the case of their mixing with muon neutrinos in the charged current. We summarize the present experimental limits, an…

Supersymmetric dark-matter Q-balls and their interactions in matter

Alexander Kusenko, Lee Loveridge, Mikhail Shaposhnikov

Supersymmetric extensions of the Standard Model contain non-topological solitons, Q-balls, which can be stable and can be a form of cosmological dark matter. Understanding the inte…

Gamma ray bursts and the origin of galactic positrons

Gianfranco Bertone, Alexander Kusenko, Sergio Palomares-Ruiz +2

A recent observation of the 511 keV electron-positron annihilation line from the Galactic bulge has prompted a debate on the origin of the galactic positrons responsible for this e…

Possible astrophysical clues of dark matter

Alexander Kusenko

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…

Pulsar kicks and dark matter from a sterile neutrino

Alexander Kusenko

The observed velocities of radio pulsars, which range in the hundreds kilometers per second, and many of which exceed 1000 km/s, are not explained by the standard physics of the su…
