In a milestone that will bear on future discoveries in nuclear and particle physics, today an international team including scientists from MIT announced that they have established a new upper limit on...
Every second, trillions of neutrinos travel through your body unnoticed. Neutrinos are among the most abundant particles in the universe, but they are difficult to study because they very rarely inter...
The sources of the high-energy cosmic neutrinos that are detected by the IceCube Neutrino Observatory buried in the Antarctic ice may be hidden from observations of high-energy gamma rays, new researc...
Exploiting the earth atmosphere as a giant detector for the incoming extraterrestrial fl ux of high energy cosmic rays and cosmic neutrinos, the mission «EUSO-Extreme Universe Space Observatory&...
A group of researchers using a massive, National Science Foundation (NSF)-funded instrument buried deep in the ice at the geographic South Pole have announced a new observation of high-energy neutrino...
AMHERST, Mass. – Using one of the most sensitive neutrino detectors on the planet, an international team of physicists including Andrea Pocar, Laura Cadonati and doctoral student Keith Otis at the Uni...
Scientists on the world's longest-distance neutrino experiment announced today that they have seen their first neutrinos.
The first dedicated search for ultra-high energy (UHE) tau neutrinos of astrophysical origin was performed using the IceCube detector in its 22-string configuration. The search also had sensitivity to...
In this paper, we report the results of constraining the dynamical dark energy with a divergence-free parameterization, $w(z) = w_{0} + w_{a}(\frac{\ln(2+z)}{1+z}-\ln2)$, in the presence of spatial cu...
The recent global fit of short baseline neutrino oscillation data favors the presence of one (or more) sterile neutrino state which leads to new mass splitting \Delta m^2 ~1 eV^2. We consider the effe...
In the internal shock model of gamma ray bursts ultrahigh energy pions, kaons and neutrons are likely to be produced in the interactions of shock accelerated relativistic protons with low energy photo...
We study the production of cosmogenic neutrinos and photons during the extragalactic propagation of ultra-high-energy cosmic rays (UHECRs). For a wide range of models in cosmological evolution of sour...
We provide an exhaustive analysis of the Integrated Sach–Wolfe effect (ISW) in the context of coupled Dark Energy cosmologies where a component of massive neutrinos is also present. We focus on the ef...
Ultra-high energy cosmic rays (UHECR) above an energy threshold of tens of EeV might undergo only small deflections due to interstellar magnetic fields. Their arrival directions would then point to re...
High-energy neutrinos, arising from decays of mesons that were produced through the cosmic rays collisions with air nuclei, form unavoidable background noise in the astrophysical neutrino detection pr...
