Selected Topics in Cosmic Ray Physics [PDF]

open access: yes, 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 ...

Cosmic Inflation and Genetic Algorithms

open access: yesFortschritte der Physik, Volume 71, Issue 1, January 2023., 2023
Abstract Large classes of standard single‐field slow‐roll inflationary models consistent with the required number of e‐folds, the current bounds on the spectral index of scalar perturbations, the tensor‐to‐scalar ratio, and the scale of inflation can be efficiently constructed using genetic algorithms.

Thunderstorm Ground Enhancements Measured on Aragats and Progress of High-Energy Physics in the Atmosphere

open access: yesAtmosphere, 2023
High-energy physics in the atmosphere (HEPA) has undergone an intense reformation in the last decade. Correlated measurements of particle fluxes modulated by strong atmospheric electric fields, simultaneous measurements of the disturbances of the near ...

Text-Book of Cosmical Physics [PDF]

open access: yesNature, 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 ...

Experiment regarding magnetic fields with gravity

open access: yesIET Quantum Communication, Volume 3, Issue 4, Page 218-228, December 2022., 2022
Abstract This experiment was designed to test the string theory as a physical reality. The ground‐based device placed the N poles of the magnets upwards, north, south, east, and west. Coil Ass'Y was placed between 2 N poles with bearing covers on the top and bottom.

Cosmic Ray Physics with the IceCube Observatory [PDF]

open access: yes, 2012
The IceCube Neutrino Observatory with its 1-km^3 in-ice detector and the 1-km^2 surface detector (IceTop) constitutes a three-dimensional cosmic ray detector well suited for general cosmic ray physics. Various measurements of cosmic ray properties, such as energy spectra, mass composition and anisotropies, have been obtained from analyses of air ...

New physics, the cosmic ray spectrum knee, and $pp$ cross section measurements

open access: yes, 2010
We explore the possibility that a new physics interaction can provide an explanation for the knee just above $10^6$ GeV in the cosmic ray spectrum. We model the new physics modifications to the total proton-proton cross section with an incoherent term ...

Astrophysical origin of high-energy cosmic neutrinos

open access: yesEPJ Web of Conferences, 2015
The origin of high-energy cosmic neutrinos is a new interesting mystery in astroparticle physics. The present data suggest interesting connection to cosmic-ray and/or gamma-ray sources.
