Invisible Labor and the "Ghost Particle": Underground Physics at the Kolar Gold Fields. [PDF]

Ber Wiss
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

The Relevance of Nuclear Reactions for Standard Solar Models Construction

Frontiers in Astronomy and Space Sciences, 2021
The fundamental processes by which nuclear energy is generated in the Sun have been known for many years. However, continuous progress in areas such as neutrino experiments, stellar spectroscopy and helioseismic data and techniques requires ever more ...

Statistical significance of the sterile-neutrino hypothesis in the context of reactor and gallium data

Journal of High Energy Physics, 2022
We evaluate the statistical significance of the 3+1 sterile-neutrino hypothesis using ν e and ν ¯ $$ \overline{\nu} $$ e disappearance data from reactor, solar and gallium radioactive source experiments.

Implications of the Dark-LMA solution for neutrino mass matrices

Nuclear Physics B, 2021
In this work we have re-investigated two different kinds of texture zero ansatz of the low energy neutrino mass matrix in view of the Dark-Large-Mixing-Angle (DLMA) solution of the solar neutrino problem which can arise in the presence of non-standard ...

Neutrinos and Asteroseismology of Stars over the Helium Flash

The Astrophysical Journal, 2023
The helium flash, occurring in stars of 0.6–2.0 M _⊙ at the end of the red giant branch, is not observable via optical means due to the energy of the process being used to lift the core out of degeneracy.

Advice for a Young Scientist

Perspectives of Earth and Space Scientists, Volume 4, Issue 1, December 2023., 2023
Abstract My career has included astrophysics and space physics, always with a theoretical emphasis. My first papers calculated nuclear reaction rates in dense stars, particularly neutron stars, but I branched out to other areas or theoretical astrophysics.

Multi‐Approach Analysis of Baroclinic Internal Tide Perturbation in the Ionian Sea Abyssal Layer (Mediterranean Sea)

Geophysical Research Letters, Volume 50, Issue 18, 28 September 2023., 2023
Abstract Despite being widely recognized, the importance of deep layers thermohaline and mixing processes in the ocean circulation and variability is still poorly investigated, especially in the Mediterranean Sea. This limits understanding and parametrizing deep dynamics, which result in evident biases in the global circulation representation by ...

First High‐Speed Video Camera Observations of a Lightning Flash Associated With a Downward Terrestrial Gamma‐Ray Flash

Geophysical Research Letters, Volume 50, Issue 14, 28 July 2023., 2023
Abstract In this paper, we present the first high‐speed video observation of a cloud‐to‐ground lightning flash and its associated downward‐directed Terrestrial Gamma‐ray Flash (TGF). The optical emission of the event was observed by a high‐speed video camera running at 40,000 frames per second in conjunction with the Telescope Array Surface Detector ...

Library of Simulated Gamma‐Ray Glows and Application to Previous Airborne Observations

Journal of Geophysical Research: Atmospheres, Volume 128, Issue 9, 16 May 2023., 2023
Abstract Gamma‐Ray Glows (GRGs) are high energy radiation originating from thunderclouds, in the MeV energy regime, with typical duration of seconds to minutes, and sources extended over several to tens of square kilometers. GRGs have been observed from detectors placed on ground, inside aircraft and on balloons.
