The influence of cosmic-rays on the magnetorotational instability [PDF]
, 2011 We present a linear perturbation analysis of the magnetorotational instability in the presence of the cosmic rays. Dynamical effects of the cosmic rays are considered by a fluid description and the diffusion of cosmic rays is only along the magnetic field lines.

COSMIC RAYS IN GALAXY CLUSTERS AND THEIR NONTHERMAL EMISSION [PDF]
, 2014 Radio observations prove the existence of relativistic particles and magnetic field associated with the intra-cluster-medium (ICM) through the presence of extended synchrotron emission in the form of radio halos and peripheral relics.

Scintillation Response of 0D Cs3Cu2I5 Thin Layers to Light‐ and Heavy‐Ion Irradiation
Advanced Photonics Research, EarlyView.Driven by increasing interest in uncovering the remarkable photoluminescence quantum yield of Cs3Cu2I5, polycrystalline thin layers are synthesized to investigate its radioluminescence response to energetic ions. Its spectroscopic capability is assessed in a wide range of ion mass and internal excitation processes are explored.

INDICATIONS OF INTERMEDIATE-SCALE ANISOTROPY OF COSMIC RAYS WITH ENERGY GREATER THAN 57 EeV IN THE NORTHERN SKY MEASURED WITH THE SURFACE DETECTOR OF THE TELESCOPE ARRAY EXPERIMENT [PDF]
, 2014 We have searched for intermediate-scale anisotropy in the arrival directions of ultrahigh-energy cosmic rays with energies above 57 EeV in the northern sky using data collected over a 5 yr period by the surface detector of the Telescope Array experiment.

High‐Throughput Single‐Nanowire Optoelectronic Characterization Using Microfluidic Technology
Advanced Photonics Research, EarlyView.An ultrathin microfluidic platform enables high‐throughput, in‐line single particle characterization of semiconductor nanowires. Using correlative spectroscopy and imaging, analysis at 240 nanowires per minute, uncovering previously hidden details about intra‐wire disorder and inter‐wire inhomogeneity, is achieved.

Spectra of He Isotopes and the 3He/4He Ratio
The Astrophysical JournalSince its launch, the Alpha Magnetic Spectrometer-02 (AMS-02) has delivered outstanding quality measurements of the spectra of cosmic-ray (CR) species, e ^± , $\bar{p}$ , and nuclei (H–Si, S, Fe), which have resulted in a number of breakthroughs. Besides

Cosmic rays, aerosol formation and cloud-condensation nuclei: sensitivities to model uncertainties [PDF]
Atmospheric Chemistry and Physics, 2011 The flux of cosmic rays to the atmosphere has been reported to correlate with cloud and aerosol properties. One proposed mechanism for these correlations is the "ion-aerosol clear-air" mechanism where the cosmic rays modulate atmospheric ion ...

Galactic cosmic ray propagation: sub-PeV diffuse gamma-ray and neutrino emission [PDF]
arXiv, 2021 The Tibet ASgamma experiment just reported their measurement of sub-PeV diffuse gamma ray emission from the Galactic disk, with the highest energy up to 957 TeV. These gamma-rays are most likely the hadronic origin by cosmic ray interaction with interstellar gas in the Galaxy.

Wave damping by MHD turbulence and its effect upon cosmic ray propagation in the ISM [PDF]
Astrophys.J. 604 (2004) 671-674, 2003 Cosmic rays scatter off magnetic irregularities (Alfven waves) with which they are resonant, that is waves of wavelength comparable to their gyroradii. These waves may be generated either by the cosmic rays themselves, if they stream faster than the Alfven speed, or by sources of MHD turbulence. Waves excited by streaming cosmic rays are ideally shaped
