The next-generation liquid-scintillator neutrino observatory LENA
Abstract As part of the European LAGUNA design study on a next-generation neutrino detector, we propose the liquid-scintillator detector LENA (Low Energy Neutrino Astronomy) as a multipurposeExpand

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 asExpand

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 aExpand

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 haveExpand

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 theExpand

Flavor composition of the high-energy neutrino events in IceCube.
The IceCube experiment has recently reported the observation of 28 high-energy (>30  TeV) neutrino events, separated into 21 showers and 7 muon tracks, consistent with an extraterrestrial origin. InExpand

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 theExpand

Constraining dark matter late-time energy injection: decays and p-wave annihilations
We use the latest cosmic microwave background (CMB) observations to provide updated constraints on the dark matter lifetime as well as on p-wave suppressed annihilation cross sections in the 1 MeV toExpand

Model-independent bound on the dark matter lifetime
Abstract If dark matter (DM) is unstable, in order to be present today, its lifetime needs to be longer than the age of the Universe, t U ≃ 4 × 10 17 s . It is usually assumed that if DM decays itExpand
