Galactic cosmic rays on extrasolar Earth-like planets - I. Cosmic ray flux [PDF]
, 2015 Context. Theoretical arguments indicate that close-in terrestial exoplanets may have weak magnetic fields, especially in the case of planets more massive than Earth (super-Earths).

The galactic cosmic ray ionization rate [PDF]
Proceedings of the National Academy of Sciences, 2006 The chemistry that occurs in the interstellar medium in response to cosmic ray ionization is summarized, and a review of the ionization rates that have been derived from measurements of molecular abundances is presented. The successful detection of large abundances of H 3 + in diffuse clouds and the ...

The THESEUS Space Mission and the Infrared Telescope Calibration Unit
Astronomische Nachrichten, EarlyView.ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Theoretical challenges in acceleration and transport of ultra high energy cosmic rays: A review
EPJ Web of Conferences, 2013 The wealth of data collected in the last few years thanks to the Pierre Auger Observatory and recently to the Telescope Array made the problem of the origin of ultra high energy cosmic rays a genuinely experimental/observational one.

Changes in cloud cover associated with Forbush decreases of galactic cosmic rays
, 2001 The results of a study to quantify the relationship between cloud cover and short-term Forbush decreases (FD) of galactic cosmic ray flux are presented. Using an extensive record of global satellite-derived cloud products from the International Satellite

Grammage of cosmic rays around Galactic supernova remnants [PDF]
, 2015 The residence time of cosmic rays (CRs) in the Galaxy is usually inferred from the measurement of the ratio of secondary-to-primary nuclei, for instance the boron (B)/carbon (C) ratio, which provides an estimate of the amount of matter traversed by CRs ...

Multiscaling of Galactic Cosmic Ray Flux
Physical Review Letters, 2003 Multiscaling analysis of differential flux dissipation rate of galactic cosmic rays (Carbon nuclei) is performed in the energy ranges: 56.3-73.4 Mev/nucleon and 183.1-198.7 MeV/nucleon, using the data collected by ACE/CRIS spacecraft instrument for 2000 year.

The Effects of Discreteness of Galactic Cosmic‐Ray Sources [PDF]
The Astrophysical Journal, 2004 Most studies of GeV Galactic Cosmic Rays (GCR) nuclei assume a steady state/continuous distribution for the sources of cosmic rays, but this distribution is actually discrete in time and in space. The current progress in our understanding of cosmic ray physics (acceleration, propagation), the required consistency in explaining several GCRs ...

Astronomische Nachrichten, EarlyView.ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...
