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

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 ...

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.

Neutrino decay and atmospheric neutrinos [PDF]
Physics Letters B, 1999 We reconsider neutrino decay as an explanation for atmospheric neutrino observations. We show that if the mass-difference relevant to the two mixed states ν_μand ν_τis very small (< 10^{-4} eV^2), then a very good fit to the observations can be obtained with decay of a component of ν_μto a sterile neutrino and a Majoron.

Sterile neutrino as a bulk neutrino [PDF]
Nuclear Physics B, 2000 If light sterile neutrinos are needed to understand the neutrino puzzles, as is currently indicated, a major theoretical challenge is to understand why its mass is so small. It is a more serious problem than understanding the small mass of the familiar neutrinos.

The Spectrum of Light Emitted by LED Using a CMOS Sensor-Based Digital Camera and Its Application
Sensors, 2022 We introduced a digital photo image analysis in color space to estimate the spectrum of fluor components dissolved in a liquid scintillator sample through the hue and wavelength relationship.

Sterile neutrinos in astrophysical neutrino flavor [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Current global constraints in neutrino mixing parameters translate to lax PMNS unitarity relations. In this work, we explore the lack of non-unitarity in the neutrino mixing matrix via the astrophysical neutrino flavor content in both standard paradigms, as well as those involving sterile neutrinos.

Neutrino interaction physics in neutrino telescopes [PDF]
The European Physical Journal Special Topics, 2021 AbstractNeutrino telescopes can observe neutrino interactions starting at GeV energies by sampling a small fraction of the Cherenkov radiation produced by charged secondary particles. These experiments instrument volumes massive enough to collect substantial samples of neutrinos up to the TeV scale as well as small samples at the PeV scale. This unique
