Cosmic Background Radiation [PDF]

International Journal of Theoretical Physics, 2015
It is shown that a collection of photons with nearly the same frequency exhibits a “condensation” type of phenomenon corresponding to a peak intensity.

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.

Looking at cosmic near-infrared background radiation anisotropies [PDF]

Reviews of Modern Physics, 2018
The cosmic infrared background (CIB) contains emissions accumulated over the entire history of the Universe, including from objects inaccessible to individual telescopic studies.

Interstellar Hydrogen and Cosmic Background Radiation [PDF]

Chaos Solitons & Fractals 12(2001) pp 1563-1564, 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. The observed cosmic background radiation can be explained from this standpoint in terms of the radiation due to fluctuations in interstellar Hydrogen.

Effect of Cosmic UV Background on Star Formation in High Redshift Galaxies [PDF]

Astrophys.J.721:L79-L81,2010, 2010
The effect of the cosmic UV background on star formation in high redshift galaxies is explored by means of high resolutions cosmological simulations. The simulations include star formation, 3D radiative transfer, and a highly detailed ISM model, and reach spatial resolution sufficient to resolve formation sites for molecular clouds.

Decoherence in the cosmic background radiation [PDF]

, 2011
In this paper we analyze the possibility of detecting nontrivial quantum phenomena in observations of the temperature anisotropy of the cosmic background radiation (CBR), for example, if the Universe could be found in a coherent superposition of two ...

TeV Blazars and Cosmic Infrared Background Radiation [PDF]

arXiv, 2001
The recent developments in studies of TeV radiation from blazars are highlighted and the implications of these results for derivation of cosmologically important information about the cosmic infrared background radiation are discussed.

A flat Universe from high-resolution maps of the cosmic microwave background radiation [PDF]

Nature, 2000
The blackbody radiation left over from the Big Bang has been transformed by the expansion of the Universe into the nearly isotropic 2.73 K cosmic microwave background.

Physics of the Cosmic Microwave Background Radiation [PDF]

Astrophys.Space Sci.Proc. 45 (2016) 3-39, 2015
The cosmic microwave background (CMB) radiation provides a remarkable window onto the early universe, revealing its composition and structure. In these lectures we review and discuss the physics underlying the main features of the CMB.

Cosmic Needles versus Cosmic Microwave Background Radiation [PDF]

, 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.
