An Assessment of the GLE Alert++ Warning System
AtmosphereOver the last years the Athens Cosmic Ray Group of the National & Kapodistrian University of Athens has implemented a warning tool called GLE Alert, which is a highly credible application that issues alerts when a ground level enhancement (GLE) starts ...

The Role of Pressure Anisotropy in Cosmic Ray Hydrodynamics [PDF]
, 2019 Cosmic ray propagation in the Milky Way and other galaxies is largely diffusive, with mean free path determined primarily by pitch angle scattering from hydromagnetic waves with wavelength of order the cosmic ray gyroradius. In the theory of cosmic ray self confinement, the waves are generated by instabilities driven by the cosmic rays themselves.

Contribution of a nearby Pulsar to Cosmic Rays observed at Earth [PDF]
Astropart.Phys. 25 (2006) 226-232, 2006 Contribution of nearby pulsars to the cosmic rays observed at Earth has been studied. It is found that the experimental bound on amplitude of cosmic ray anisotropy may produce significant constraint on the efficiency of converting pulsar rotational energy to emitted particles kinetic energy.

Particles, Strings and Cosmology (PASCOS 99), 2000 Cosmic ray antiprotons have been detected for over 20 years and are now measured reliably. Standard particle and astrophysics predict a conventional spectrum and abundance of secondary antiprotons consistent with all current measurements. These measurements place limits on exotic Galactic antiproton sources and non-standard antiproton properties ...

Molecular Clouds as Cosmic Ray Laboratories
, 2011 We will here discuss how the gamma-ray emission from molecular clouds can be used to probe the cosmic ray flux in distant regions of the Galaxy and to constrain the highly unknown cosmic ray diffusion coefficient. In particular we will discuss the GeV to

Cosmic ray short burst observed with the Global Muon Detector Network (GMDN) on June 22, 2015 [PDF]
, 2018 We analyze the short cosmic ray intensity increase ("cosmic ray burst": CRB) on June 22, 2015 utilizing a global network of muon detectors and derive the global anisotropy of cosmic ray intensity and the density (i.e.

Advanced Science, EarlyView.This study presents a novel polyphenol‐nanozyme‐armored probiotic system (ECA@EcN) for enhanced treatment of inflammatory bowel disease (IBD). By integrating chitosan‐modified epigallocatechin gallate (EGCG‐CS) with gold nanozymes, the system effectively scavenges ROS, improves probiotic viability, and restores gut microbiota balance.

Unparticle effects on cosmic ray photon and $e^\pm$
, 2009 We study the effects of unparticle physics on the cosmic ray photon and $e^\pm$, including on the pair production (PP) and elastic scattering (ES) of cosmic ray photon off various background radiations, and on the inverse Compton scattering of cosmic ray

Connecting blazars with ultra high energy cosmic rays and astrophysical neutrinos [PDF]
, 2017 We present a strong hint of a connection between high energy $\gamma$-ray emitting blazars, very high energy neutrinos, and ultra high energy cosmic rays.
