An Upper Limit to Arcminute-Scale Anisotropy in the Cosmic Microwave Background Radiation at 142 GHz [PDF]
, 1997 We present limits to anisotropies in the cosmic microwave background radiation (CMB) at angular scales of a few arcminutes. The observations were made at a frequency of 142 GHz using a six-element bolometer array (the Sunyaev-Zel'dovich Infrared ...

Spectral Distortion of Cosmic Microwave Background Radiation by Scattering on Hot Electrons: Exact Calculations [PDF]
, 2000 The spectral distortion of the cosmic microwave background radiation produced by the inverse Compton scattering on hot electrons in clusters of galaxies (thermal Sunyaev-Zeldovich effect) is calculated for arbitrary optical depth and electron temperature.

On parton distributions in a photon gas [PDF]
Eur.Phys.J.C65:269-273,2010, 2008 In some cases it may be useful to know parton distributions in a photon gas. This may be relevant, e.g., for the analysis of interactions of high energy cosmic ray particles with the cosmic microwave background radiation. The latter can be considered as a gas of photons with an almost perfect blackbody spectrum.

Extrapolation of Galactic Dust Emission at 100 Microns to Cosmic Microwave Background Radiation Frequencies Using FIRAS [PDF]
, 1999 We present predicted full-sky maps of submillimeter and microwave emission from the diffuse interstellar dust in the Galaxy. These maps are extrapolated from the 100 μm emission and 100/240 μm flux ratio maps that Schlegel, Finkbeiner, & Davis generated ...

Cosmological production of vector bosons and cosmic microwave background radiation [PDF]
, 2004 An intensive cosmological production of vector W and Z bosons is considered within a cosmological model that involves a relative scale of measurement. Field-theory models are studied in which cosmic microwave background radiation and baryon matter may ...

Limits on the Polarization of the Cosmic Microwave Background Radiation at Multipoles up to l ~ 2000 [PDF]
, 2005 We report upper limits on the polarization of the cosmic microwave background radiation (CMBR) as measured with the Cosmic Background Imager (CBI), a 13 element interferometer that operates in the 26-36 GHz band and is sited on Llano de Chajnantor in ...

Stringent Limit on Primordial Magnetic Fields from the Cosmic Microwave Background Radiation. [PDF]
Physical Review Letters, 2018 Primordial magnetic fields (PMFs), being present before the epoch of cosmic recombination, induce small-scale baryonic density fluctuations. These inhomogeneities lead to an inhomogeneous recombination process that alters the peaks and heights of the ...
