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

open access: yesGeophysical 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 ...

Future Long-Baseline Neutrino Facilities and Detectors [PDF]

open access: yes, 2013
We review the ongoing effort in the US, Japan, and Europe of the scientific community to study the location and the detectorperformance of the next-generation long-baseline neutrino facility.

Neutrino treatment in multidimensional astrophysical simulations : a new spectral scheme [PDF]

open access: yes, 2014
Neutrinos play a central role in modern physics and astrophysics. Their extremely weak interaction rate with baryons and other leptons makes their detection on the Earth difficult and challenging.

Solar Neutrinos

open access: yesAdvances in High Energy Physics, 2013
The study of solar neutrinos has given a fundamental contribution both to astroparticle and to elementary particle physics, offering an ideal test of solar models and offering at the same time relevant indications on the fundamental interactions among ...

Sensitivity of a low threshold directional detector to CNO-cycle solar neutrinos

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
A first measurement of neutrinos from the CNO fusion cycle in the Sun would allow a resolution to the current solar metallicity problem. Detection of these low-energy neutrinos requires a low-threshold detector, while discrimination from radioactive ...

Solar Models and Astrophysical S-factors Constrained by Helioseismic Results and Updated Neutrino Fluxes

open access: yesThe Astrophysical Journal
The ratio of metal abundance to hydrogen abundance of the solar photosphere, ( Z / X ) _s , has been revised several times. Standard solar models, based on these revised solar abundances, are in disagreement with seismically inferred results.

Gravitational Radiation From Binary Systems With Time Varying Masses

open access: yesAnnalen der Physik, Volume 538, Issue 8, August 2026.
We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.
