Nonthermal neutrinos from supernovae leaving a magnetar (2008)
Horiuchi, Shunsaku, Suwa, Yudai, Takami, Hajime, Ando, Shin'ichiro, Sato, Katsuhiko
Under the fossil field hypothesis of the origin of magnetar magnetic fields, the magnetar inherits its magnetic field from its progenitor. We show that during the supernova of such a progenitor,...
High-energy neutrinos from reverse shocks in choked and successful relativistic jets (2008)
Horiuchi, Shunsaku, Ando, Shin'ichiro
Highly relativistic jets are a key element of current gamma-ray burst models, where the jet kinetic energy is converted to radiation energy at optically thin shocks. High-energy neutrinos are also...
Neutrino constraints on the dark matter total annihilation cross section (2007)
Yüksel, Hasan, Horiuchi, Shunsaku, Beacom, John F., Ando, Shin'ichiro
In the indirect detection of dark matter through its annihilation products, the signals depend on the square of the dark matter density, making precise knowledge of the distribution of dark matter in...

Horiuchi, Shunsaku, Ando, Shin'ichiro
We investigate contributions to the extragalactic gamma-ray background (EGB) due to neutralino dark matter (DM) pair-annihilation into photons, from DM density enhancements (minispikes) surrounding...
