Polarization of the cosmic background radiation [PDF]
The Astrophysical Journal, 1981 The technique and results of a measurement of the linear polarization of the cosmic background radiation at a wavelength of 9 mm are discussed. Data taken between 1978 May and 1980 February from both the Northern Hemisphere (Berkeley latitude 38 deg N) and the Southern Hemisphere (Lima latitude 12 deg S) over 11 declinations from -37 to +63 deg show ...

Light bending in radiation background [PDF]
Journal of Cosmology and Astroparticle Physics, 2014 We consider the velocity shift of light in presence of radiation emitted by a black body. Within geometric optics formalism we calculate the bending angle of a light ray when there is a gradient in the energy density. We model the bending for two simplified cases.

Intergalactic UV Background Radiation Field [PDF]
, 1997 We have performed proximity effect analysis of low and high resolution data, considering detailed frequency and redshift dependence of the AGN spectra processed through galactic and intergalactic material.

The cosmic microwave background radiation [PDF]
Physics Reports, 2000 We summarize the theoretical and observational status of the study of the Cosmic Microwave Background radiation. Its thermodynamic spectrum is a robust prediction of the Hot Big Bang cosmology and has been confirmed observationally. There are now 76 observations of Cosmic Microwave Background anisotropy, which we present in a table with references.

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.

Looking at cosmic near-infrared background radiation anisotropies [PDF]
, 2018 The cosmic infrared background (CIB) contains emissions accumulated over the entire history of the Universe, including from objects inaccessible to individual telescopic studies.

On the Ultraviolet Background Radiation of the Galaxy [PDF]
Symposium - International Astronomical Union, 1985 Observations of the far-UV spectrum (1300–1800 å) of the sky background at different galactic latitudes are presented. The measurements were made in deep space, at distances up to 2 × 105 km from the Earth with the photoelectric spectrometer (“Galaktika”) on board the “Prognoz-6” satellite.

Spectrum of the microwave background radiation [PDF]
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1982 A review is given of the present status of measurements of the spectrum of the microwave background. Factors that limit experimental accuracy are discussed with particular reference to high-frequency measurements. A selection of the available measurements yields a data set that is reasonably consistent with the black-body spectrum for a temperature of ...

Formation of Sub-galactic Clouds under UV Background Radiation [PDF]
, 1999 The effects of the UV background radiation on the formation of sub-galactic clouds are studied by means of one-dimensional hydrodynamical simulations. The radiative transfer of the ionizing photons due to the absorption by HI, HeI and HeII, neglecting ...
