Cosmic Tachyon Background Radiation [PDF]

International Journal of Modern Physics A, 1999
The equilibrium statistical mechanics of a background radiation of superluminal particles is investigated, based on a vectorial wave equation for tachyons of the Proca type.

Neutrinos and Big Bang Nucleosynthesis [PDF]

Advances in High Energy Physics, 2012
According to the standard models of particle physics and cosmology, there should be a background of cosmic neutrinos in the present Universe, similar to the cosmic microwave photon background.

Cosmic Needles versus Cosmic Microwave Background Radiation [PDF]

The Astrophysical Journal, 2002
It has been suggested by a number of authors that the 2.7K cosmic microwave background (CMB) radiation might have arisen from the radiation from Population III objects thermalized by conducting cosmic graphite/iron needle-shaped dust.

Interstellar Hydrogen and Cosmic Background Radiation [PDF]

Chaos, Solitons & Fractals, 2000
It is shown that a collection of photons with nearly the same frequency exhibits a "condensation" type of phenomenon corresponding to a peak intensity.

Nuclear Physics Meets the Sources of the Ultra-High Energy Cosmic Rays [PDF]

Scientific Reports, 2017
The determination of the injection composition of cosmic ray nuclei within astrophysical sources requires sufficiently accurate descriptions of the source physics and the propagation – apart from controlling astrophysical uncertainties.

Cosmic Microwave Background Radiation Anisotropy Induced by Cosmic Strings

, 1994
We report on a current investigation of the anisotropy pattern induced by cosmic strings on the cosmic microwave background radiation (MBR). We have numerically evolved a network of cosmic strings from a redshift of $Z = 100$ to the present and ...

Gravitational wave memory produced by cosmic background radiation

Physics Letters B, 2023
It is well known that energy fluxes will produce gravitational wave memory. The gravitational wave memory produced by background including cosmic microwave background (CMB), cosmic neutrino background (CνB), and gravitational wave background is ...

Measurement of background radiation in Jhapa, Ilam, Panchthar, and Taplejung districts of Nepal

Bibechana, 2023
In this study, we investigated the levels of background radiation in different locations across the Eastern part of Koshi province, specifically in Taplejung, Panchthar, Ilam, and Jhapa.
