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. The partition function, the spectral energy density, and the various thermodynamic variables of an ideal Bose gas of tachyons in an open Robertson–Walker cosmology are derived ...

THE COSMIC MICROWAVE BACKGROUND RADIATION* [PDF]
Annals of the New York Academy of Sciences, 1981 Because angular anisotropies and spectral distortions of the cosmic microwave background radiation are judged to be inevitable at some level, in a realistic cosmological model, the evidence for spectral distortions and its theoretical implications are described.

On the (Higher Multipoles) Variance Asymmetry in the Cosmic Microwave Background
The Astrophysical JournalWe have studied the cosmic microwave background (CMB) map looking for features beyond cosmological isotropy. We began by tiling the CMB variance maps (which are produced by different smoothing scales) with stripes of different sizes along the most ...

A review on natural background radiation
Advanced Biomedical Research, 2013 The world is naturally radioactive and approximately 82% of human-absorbed radiation doses, which are out of control, arise from natural sources such as cosmic, terrestrial, and exposure from inhalation or intake radiation sources.

Advanced Functional Materials, EarlyView.Walnut seeds are enclosed in a remarkably strong shell made of sclerenchyma, separated by a pectin‐rich suture tissue. Different cell shapes and chemical composition of this tissue point to an opening mechanism, which is triggered by cyclic humidity changes.

A Measurement of Atmospheric Circular Polarization with POLARBEAR
The Astrophysical JournalAt millimeter wavelengths, the atmospheric emission is circularly polarized owing to the Zeeman splitting of molecular oxygen by the Earth's magnetic field.
