Characterization of subhalo structural properties and implications for dark matter annihilation signals

Low reheating temperature and the visible sterile neutrino.
We present here a scenario, based on a low reheating temperature T(R)<<100 MeV at the end of (the last episode of) inflation, in which the coupling of sterile neutrinos to active neutrinos can be as
Non-standard interactions with high-energy atmospheric neutrinos at IceCube
A bstractNon-standard interactions in the propagation of neutrinos in matter can lead to significant deviations from expectations within the standard neutrino oscillation framework and atmospheric
Spectral analysis of the high-energy IceCube neutrinos
A full energy and flavor-dependent analysis of the three-year high-energy IceCube neutrino events is presented. By means of multidimensional fits, we derive the current preferred values of the
Analysis of the 4-year IceCube high-energy starting events
After four years of data taking, the IceCube neutrino telescope has detected 54 high-energy starting events (HESE, or contained-vertex events) with deposited energies above 20 TeV. They represent the
Explaining LSND by a decaying sterile neutrino
We propose an explanation of the LSND evidence for electron antineutrino appearance based on neutrino decay. We introduce a heavy neutrino, which is produced in pion and muon decays because of a
Dark matter in the Sun: scattering off electrons vs nucleons
The annihilation of dark matter (DM) particles accumulated in the Sun could produce a flux of neutrinos, which is potentially detectable with neutrino detectors/telescopes and the DM elastic
TeV γ rays and neutrinos from photodisintegration of nuclei in Cygnus OB2
TeV {gamma}-rays may provide significant information about high energy astrophysical accelerators. Such {gamma}-rays can result from the photo-de-excitation of PeV nuclei after their parents have
Testing MeV dark matter with neutrino detectors
MeV particles have been advocated as dark matter (DM) candidates in different contexts. This hypothesis can be tested indirectly by searching for the standard model (SM) products of DM
