Cosmic vortons and particle physics constraints [PDF]

open access: yesPhysical Review D, 1996
We investigate the cosmological consequences of particle physics theories that admit stable loops of superconducting cosmic string - {\it vortons}. General symmetry breaking schemes are considered, in which strings are formed at one energy scale and subsequently become superconducting in a secondary phase transition at what may be a considerably lower ...

Cosmic neutrino flux and spin flavor oscillations in intergalactic medium

open access: yesPhysics Letters B, 2023
The ultra high energy (UHE) cosmic neutrinos are expected to play a pivotal role in the disquisition of physics beyond the standard model of particle physics as well as serve as an ideal cosmic messengers.

The cosmic microwave background bispectrum from the non-linear evolution of the cosmological perturbations [PDF]

open access: yes, 2010
International audienceThis article presents the first computation of the complete bispectrum of the cosmic microwave background temperature anisotropies arising from the evolution of all cosmic fluids up to second order, including neutrinos ...

The Physics of Cosmic Acceleration [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2009
The discovery that the cosmic expansion is accelerating has been followed by an intense theoretical and experimental response in physics and astronomy. The discovery implies that our most basic notions about how gravity works are violated on cosmological distance scales. A simple fix is to introduce a cosmological constant into the field equations for

Jupiter as a giant cosmic ray detector [PDF]

open access: yes, 2014
All authors highlight financial support of the European Community under the FP7 by an ERC starting grant.We explore the feasibility of using the atmosphere of Jupiter to detect ultra-high-energy cosmic rays (UHECRs).

ARGO-YBJ: Highlights and Prospects

open access: yesActa Polytechnica CTU Proceedings, 2014
The ARGO-YBJ experiment has been in stable data taking for 5 years at the YangBaJing Cosmic Ray Laboratory (Tibet, P.R. China, 4300 m a.s.l., 606 g/cm2). With a duty-cycle greater than 86% the detector collected about 51011 events in a wide energy range,

Chapter 4 Cosmic-Ray Physics * [PDF]

open access: yesChinese Physics C, 2022
Abstract In the first part of this Chapter the present state of knowledge from the observations of cosmic rays between 1013 and 1020 eV is summarized. This is not intended to be a complete review, but rather a broad overview of the relevant processes involving cosmic rays, including the astrophysical environments in which they take place.
