Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields** [PDF]

Berichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 163-179, August 2025.
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.

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 ...

Is bi-maximal mixing compatible with the large angle MSW solution of the solar neutrino problem? [PDF]

, 1998
It is shown that the large angle MSW solution of the solar neutrino problem with a bi-maximal neutrino mixing matrix implies an energy-independent suppression of the solar nu_e flux.

Standard Solar Neutrinos [PDF]

, 1996
An improved standard solar model has been used to calculate the fluxes of standard solar neutrinos. It includes premain sequence evolution, element diffusion, partial ionization effects, and all the possible nuclear reactions between the main elements ...

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.

Long‐Term Density Trend in the Mesosphere and Lower Thermosphere From Occultations of the Crab Nebula With X‐Ray Astronomy Satellites

Journal of Geophysical Research: Space Physics, Volume 128, Issue 2, February 2023., 2023
Abstract We present long‐term density trends of the Earth's upper atmosphere at altitudes between 71 and 116 km, based on atmospheric occultations of the Crab Nebula observed with X‐ray astronomy satellites, ASCA, RXTE, Suzaku, NuSTAR, and Hitomi. The combination of the five satellites provides a time period of 28 years from 1994 to 2022.

Analysis of Solar Neutrino Data from Super-Kamiokande I and II

Entropy, 2014
We are going back to the roots of the original solar neutrino problem: the analysis of data from solar neutrino experiments. The application of standard deviation analysis (SDA) and diffusion entropy analysis (DEA) to the Super-Kamiokande I and II data ...
