Estimation of Radiation Exposure for Various Flights from Athens International Airport

Atmosphere
In recent decades, the exposure of aviation crews and passengers to cosmic radiation has been progressively increasing due to the growing need of flights.

On The Origin of Very High Energy Cosmic Rays

, 2005
We discuss the most recent developments in our understanding of the acceleration and propagation of cosmic rays up to the highest energies. In particular we specialize our discussion to three issues: 1) developments in the theory of particle acceleration

Probing the BSM physics with CMB precision cosmology: an application to supersymmetry

Journal of High Energy Physics, 2018
The cosmic history before the BBN is highly determined by the physics that operates beyond the Standard Model (BSM) of particle physics and it is poorly constrained observationally.

Selected Topics in Cosmic Ray Physics

, 2017
The search for the origin of cosmic rays is as active as ever, mainly driven by new insights provided by recent pieces of observation. Much effort is being channelled in putting the so called supernova paradigm for the origin of galactic cosmic rays on ...

Identifying MESSENGER Magnetospheric Boundary Crossings Using a Random Forest Region Classifier

Journal of Geophysical Research: Machine Learning and Computation
We present a new list of bow shock and magnetopause crossings based on automated region classification for the MESSENGER (Mercury Surface, Space Environment, Geochemistry and Ranging) mission.

Transforming DIY Geiger Counter Kits into Muon Detectors for Education and Scientific Exploration

Particles
Any Geiger counter can be used as an effective cosmic ray detector on its own. In fact, it is known that even in the absence of a radioactive source, the instrument detects what is known as background radiation, which consists of various types of ...

Paradigm transition in cosmic plasma physics

Geophysical Research Letters, 1982
During the 1970's in situ measurements in the magnetospheres, including the solar wind region ("solar magnetosphere") drastically changed our understanding of the properties of cosmic plasmas. Further, we have learned how to generalize results from plasma investigations in one region to other regions.

Cosmic X-ray physics [PDF]

The soft X-ray sky survey data are combined with the results from the UXT sounding rocket payload. Very strong constraints can then be placed on models of the origin of the soft diffuse background.

Text-Book of Cosmical Physics [PDF]

Nature, 1894
NEARLY everyone who has become at all acquainted with popular German scientific works will have at some time fallen in with this well-known book by Dr. Muller. It first appeared in the year 1856, and received particular favour, in that in the first place it was really popularly written, and secondly, that it was useful as a book of reference for many ...
