Decoherence in the cosmic background radiation [PDF]

Classical and Quantum Gravity, 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 ...

Interstellar hydrogen and cosmic background radiation [PDF]

Chaos, Solitons & Fractals, 2001
It is shown that a collection of photons with nearly the same frequency exhibits a "condensation" type of phenomenon corresponding to a peak intensity.

Cosmic Needles versus Cosmic Microwave Background Radiation [PDF]

The Astrophysical Journal, 2003
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.

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.

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.

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.

Peak-peak correlations in the cosmic background radiation from cosmic strings [PDF]

, 2013
We examine the two-point correlation function of local maxima in temperature fluctuations at the last scattering surface when this stochastic field is modified by the additional fluctuations produced by straight cosmic strings via the Kaiser-Stebbins ...

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.

Testing isotropy of cosmic microwave background radiation [PDF]

, 2008
We introduce new symmetry-based methods to test for isotropy in cosmic microwave background radiation. Each angular multipole is factored into unique products of power eigenvectors, related multipoles and singular values that provide 2 new rotationally ...

Imprints of relic gravitational waves in cosmic microwave background radiation [PDF]

, 2006
A strong variable gravitational field of the very early Universe inevitably generates relic gravitational waves by amplifying their zero-point quantum oscillations.
