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

The evolution and history of Vinca alkaloids: From the Big Bang to the treatment of pediatric acute leukemia

open access: yesPediatric Blood &Cancer, Volume 71, Issue 11, November 2024.
Abstract An attractive flower from the island of Madagascar has in part saved the lives of thousands of children with acute lymphoblastic leukemia (ALL). Random mutations and alterations to the genome led to the evolution of genes encoding enzymes, which would provide the periwinkle flower an arsenal of secondary metabolites to survive within the ...

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 ...

Bounds on non-standard interactions of neutrinos from IceCube DeepCore data

open access: yesJournal of High Energy Physics, 2020
New physics in neutrino sector can reveal itself via non-standard neutrino in- teractions which can result in modification of the standard picture of neutrino propagation in matter.

Neutrino Oscillation Effects on the Luminosity of Neutrino-dominated Accretion Flows around Black Holes

open access: yesThe Astrophysical Journal
A stellar-mass black hole surrounded by the neutrino-dominated accretion flow (NDAF) has been proposed as the central engine of gamma-ray bursts. In this work, we investigate the neutrino/antineutrino luminosity and annihilation luminosity from the NDAF ...

Radiative emission of neutrino pairs in atoms and light sterile neutrinos

open access: yesPhysics Letters B, 2015
The process of Radiative Emission of Neutrino Pair (RENP) in atoms is sensitive to the absolute neutrino mass scale, the type of spectrum neutrino masses obey and the nature – Dirac or Majorana – of massive neutrinos.

Search for two-neutrino double electron capture on 124Xe with the XMASS-I detector

open access: yesPhysics Letters B, 2016
Double electron capture is a rare nuclear decay process in which two orbital electrons are captured simultaneously in the same nucleus. Measurement of its two-neutrino mode would provide a new reference for the calculation of nuclear matrix elements ...
