Status of cosmic-ray antideuteron searches

, 2015
The precise measurement of cosmic-ray antiparticles serves as important means for identifying the nature of dark matter. Recent years showed that identifying the nature of dark matter with cosmic-ray positrons and higher energy antiprotons is difficult ...

Extrapolation of proton-proton cross section to cosmic ray energies using geometrical model

EPJ Web of Conferences, 2017
We present a new parameterization of the hadronic matter distribution in the geometrical picture of elastic scattering. Our model contains four free energy-dependent parameters that allows us to propose a better description of differential elastic cross ...

On the Source Contribution to the Galactic Diffuse Gamma Rays above 398 TeV Detected by the Tibet ASγ Experiment

The Astrophysical Journal Letters
Potential contribution from gamma-ray sources to the Galactic diffuse gamma rays observed above 100 TeV (sub-PeV energy range) by the Tibet AS γ experiment is an important key to interpreting recent multimessenger observations.

Cosmic Rays and Gamma Ray Bursts From Microblazars [PDF]

arXiv, 1998
Highly relativistic jets from merger and accretion induced collapse of compact stellar objects, which may produce the cosmological gamma ray bursts (GRBs), are also very efficient and powerful cosmic ray accelerators. The expected luminosity, energy spectrum and chemical composition of cosmic rays from Galactic GRBs, most of which do not point in our ...

Soil water content in southern England derived from a cosmic‐ray soil moisture observing system – COSMOS‐UK

, 2016
Cosmic‐ray soil moisture sensors have the advantage of a large measurement footprint (approximately 700 m in diameter) and are able to operate continuously to provide area‐averaged near‐surface (top 10–20 cm) volumetric soil moisture content at the field

The basis for cosmic ray feedback: Written on the wind

Physics of Plasmas, 2016
Star formation and supermassive black hole growth in galaxies appear to be self-limiting. The mechanisms for self-regulation are known as feedback. Cosmic rays, the relativistic particle component of interstellar and intergalactic plasma, are among the ...
