On the Role of Electron Precipitation in Excess Radiation Doses Measured at Aviation Altitudes

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Radiation from space in the form of galactic cosmic rays (GCRs) generates a persistent background of ionizing radiation in Earth's atmosphere. The dose rate of ionizing radiation due to GCRs increases from sea level to aviation altitudes.

Solar modulation of galactic cosmic rays electrons and positrons over the 23rd solar minimum with the pamela experiment

, 2013
The satellite-borne PAMELA experiment has been continuously collecting data since 15th June 2006, when it was launched from the Baikonur cosmodrome to detect the charged component of cosmic rays over a wide energy range and with an unprecedented ...

A Cosmic Ray Acceleration Mechanism Based on Background Flow Velocity Inhomogeneities Yielding Power-law Spectra

The Astrophysical Journal
In astrophysics, one significant challenge lies in understanding the acceleration of cosmic rays, which leads to the occurrence of a power law. In this article, momentum transport generated by the combined effects of pitch-angle diffusion and background ...

Energetic particles accelerated via turbulent magnetic reconnection in protoplanetary discs – I. Ionisation rates

Astronomy & Astrophysics
Context. Ionisation controls the chemistry, thermal balance, and magnetic coupling in protoplanetary discs. However, standard ionisation vectors such as stellar UV, X-rays, Galactic cosmic rays might not be efficient enough, as UV/X-rays are attenuated ...

Integrating simultaneous interfacial shear rheology with neutron reflectometry for structural and dynamic analysis of fluid interfacial systems

Journal of Applied Crystallography, Volume 59, Issue 3, Page 751-764, June 2026.
We present a new setup at the FIGARO horizontal neutron reflectometer enabling simultaneous measurement of the structural and mechanical properties of liquid interfaces, combining neutron reflectometry with interfacial shear rheology.The study of the structure and mechanical properties of complex fluid interfaces has attracted growing interest in ...

The AMS-02 Cosmic-Ray Deuteron Flux is Consistent with a Secondary Origin

The Astrophysical Journal Letters
The recent measurements of cosmic-ray (CR) deuteron fluxes by AMS-02 show that the rigidity dependence of deuterons is similar with that of protons but flatter than ^3 He, which has been attributed to the existence of primary deuterons with abundance ...

Cosmic X-Ray Sources-Galactic and Extragalactic.

The Astronomical Journal, 1966
Instruments carried aboard an Aerobee rocket in April 1965 provided evidence for x-ray emission from the directions of the radio galaxies Cygnus A and M-87 and from the galactic supernova remnant Cassiopeia A. A survey of the Cygnus region revealed a marked decrease in the flux of x-rays from Cygnus XR-1, which was identified in June 1964 as the second
