The Distribution of Ultrahigh-energy Cosmic Rays along the Supergalactic Plane Measured at the Pierre Auger Observatory

open access: yesThe Astrophysical Journal
Ultrahigh-energy cosmic rays are known to be mainly of extragalactic origin, and their propagation is limited by energy losses, so their arrival directions are expected to correlate with the large-scale structure of the local Universe.

Exploring the Components of Cosmogenic UHECR, Neutrino, and Diffuse Gamma Ray from High-Energy Astrophysical Objects

open access: yesGalaxies
The development of multimessenger astrophysics allows us to probe various background particles from the distant early universe. Up to now, much effort has been made researching the emission and radiation of diverse steady or transient astrophysical ...

The chemical composition and energy content of the energetic cosmic radiation [PDF]

open access: yes, 1972
A brief survey is made of our present knowledge of the composition and energy spectra of the primary cosmic radiation. The total energy carried by all forms of cosmic radiation that have appreciable penetrability into matter has been ...

Phenotypic Cuticle Plasticity at High Elevation: Is Microstructure and Microchemistry Related to Water Permeability?

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Kalmia procumbens (K. procumbens), a ubiquitous alpine dwarf shrub, thrives at high elevations, particularly on wind‐exposed sites. Plants on contrasting north‐ and southeast‐facing slopes at ~2237 m elevation exhibit differences in leaf colour and growth, suggesting acclimative strategies.

Cre Experiment on KITSAT-1 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1994
The Cosmic Ray Experiment (CRE) is one of the modules flown on board the KITSAT-1 satellite and consists of two sub-systems: the Total Dose Experiment (TDE) and the Cosmic Particle Experiment (CPE).

Microbially generated ferruginous crusts: A potential biosignature of continental input in coastal settings

open access: yesSedimentology, EarlyView.
ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

open access: yesExperimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.
