A Brief, Biased View of Neutron Star Cooling

open access: yesAstronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT This is a concise and non‐technical review of topics related to neutron star (NS) cooling, for both young NSs and NSs in low‐mass x‐ray binaries. Neutrino emission from the NS core drives cooling rates, via different processes including Urca processes and pair breaking and formation at the neutron superfluid critical temperature.

Intermediate Fluence Downward Terrestrial Gamma Ray Flashes as Observed by the Telescope Array Surface Detector

open access: yesJournal of Geophysical Research: Atmospheres, Volume 129, Issue 24, 28 December 2024.
Abstract On 11 September 2021, two small thunderstorms developed over the Telescope Array Surface Detector (TASD) that produced an unprecedented number of six downward terrestrial gamma ray flashes (TGFs) within one‐hour timeframe. The TGFs occurred during the initial stage of negative cloud‐to‐ground flashes whose return strokes had increasingly large

Search for Neutrino Doublets and Triplets Using 11.4 yr of IceCube Data

open access: yesThe Astrophysical Journal
We report a search for high-energy astrophysical neutrino multiplets, detections of multiple neutrino clusters in the same direction within 30 days, based on an analysis of 11.4 yr of IceCube data.

Double Beta Decay Experiments With Loaded Liquid Scintillator

open access: yesFrontiers in Physics, 2019
Liquid scintillator detectors have many properties which are highly advantageous for neutrino research at the MeV energy scale. There are various choices of additives to an organic liquid scintillator which typically function as the nuclear targets in a ...

A Search for IceCube Sub-TeV Neutrinos Correlated with Gravitational-wave Events Detected By LIGO/Virgo

open access: yesThe Astrophysical Journal, 2023
The LIGO/Virgo collaboration published the catalogs GWTC-1, GWTC-2.1, and GWTC-3 containing candidate gravitational-wave (GW) events detected during its runs O1, O2, and O3. These GW events can be possible sites of neutrino emission.

GOES‐R Series X‐Ray Sensor (XRS): 1. Design and Pre‐Flight Calibration

open access: yesJournal of Geophysical Research: Space Physics, Volume 129, Issue 11, November 2024.
Abstract The X‐Ray Sensor (XRS) has been making full‐disk observations of the solar soft X‐ray irradiance onboard National Oceanic and Atmospheric Administration's (NOAA) Geostationary Operational Environmental Satellites since 1975. Critical information about solar activity for space weather operations is provided by XRS measurements, such as the ...

Neutrino Astronomy with IceCube [PDF]

open access: yesProceedings of the International Astronomical Union, 2016
AbstractThe IceCube Neutrino Observatory is a cubic kilometer neutrino telescope located at the Geographic South Pole. Cherenkov radiation emitted by charged secondary particles from neutrino interactions is observed by IceCube using an array of 5160 photomultiplier tubes embedded between a depth of 1.5 km to 2.5 km in the Antarctic glacial ice.

Multi-Messenger Connection in High-Energy Neutrino Astronomy

open access: yesUniverse
Low fluxes of astrophysical neutrinos at TeV energies, and the overwhelming background of atmospheric neutrinos below that, render the current paradigm of neutrino astronomy a severely statistics-limited one.
