Physical mechanism of core-collapse supernovae that neutrinos drive [PDF]

Proceedings of the Japan Academy. Series B, Physical and Biological Sciences
The current understanding of the mechanism of core-collapse supernovae (CCSNe), one of the most energetic events in the universe associated with the death of massive stars and the main formation channel of compact objects such as neutron stars and black ...

Sterile Neutrinos with Neutrino Telescopes [PDF]

Universe, 2021
Searches for light sterile neutrinos are motivated by the unexpected observation of an electron neutrino appearance in short-baseline experiments, such as the Liquid Scintillator Neutrino Detector (LSND) and the Mini Booster Neutrino Experiment (MiniBooNE). In light of these unexpected results, a campaign using natural and anthropogenic sources to find

Possible Indications of Variations in the Directionality of Beta-Decay Products

Frontiers in Physics, 2021
Some experiments seem to yield strong evidence of variability of beta-decay rates, but other experiments may show little or no such evidence. Some recent experiments help clarify the situation.

Scintillating Bubble Chambers for Rare Event Searches

Universe, 2023
The Scintillating Bubble Chamber (SBC) collaboration is developing liquid-noble bubble chambers for the detection of sub-keV nuclear recoils. These detectors benefit from the electron recoil rejection inherent in moderately-superheated bubble chambers ...

Breakthrough Multi-Messenger Astrophysics with the THESEUS Space Mission

Galaxies, 2022
The mission concept THESEUS (Transient High Energy Sky and Early Universe Surveyor) aims at exploiting Gamma-Ray Bursts (GRB) to explore the early Universe, as well as becoming a cornerstone of multi-messenger and time-domain astrophysics.

Neutrinos [PDF]

Proceedings of the National Academy of Sciences, 1999
Neutrinos represent a new “window” to the Universe, spanning a large range of energy. We discuss the science of neutrino astrophysics and focus on two energy regimes. At “lower” energies (≈1 MeV), studies of neutrinos born inside the sun, or produced in interactions of cosmic rays with the atmosphere, have allowed the first incontrovertible evidence ...

Integral Fluxes of Neutrinos and Gamma-Rays Emitted from Neighboring X-ray Binaries

Universe, 2023
Astrophysical plasma ejections (jets) are formed and powered by black holes that accrete material from their companion star in binary systems. Black hole X-ray binary systems constitute potential powerful galactic and extragalactic neutrino and gamma-ray

Unveiling the outer core composition with neutrino oscillation tomography

Frontiers in Earth Science, 2023
In the last 70 years, geophysics has established that the Earth’s outer core is an FeNi alloy containing a few percent of light elements, whose nature and amount remain controversial. Besides the classical combinations of silicon and oxygen, hydrogen has

Squeezing the Parameter Space for Lorentz Violation in the Neutrino Sector with Additional Decay Channels

Particles, 2020
The hypothesis of Lorentz violation in the neutrino sector has intrigued scientists for the last two to three decades. A number of theoretical arguments support the emergence of such violations, first and foremost for neutrinos, which constitute the ...

Neutrino velocity and neutrino oscillations [PDF]

Physical Review D, 2012
We study distances of propagation and the group velocities of the muon neutrinos in the presence of mixing and oscillations assuming that Lorentz invariance holds. Oscillations lead to distortion of the $ν_μ$ wave packet which, in turn, changes the group velocity and the distance $ν_μ$ travels.
