Radiometer system to map the cosmic background radiation [PDF]
Review of Scientific Instruments, 1978 We have developed a 33-GHz airborne radiometer system to map large angular scale variations in the temperature of the 3 K cosmic background radiation. A ferrite circulator switches a room-temperature mixer between two antennas pointing 60° apart in the sky.

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 ...

Gravitational wave memory produced by cosmic background radiation
Physics Letters B, 2023 It is well known that energy fluxes will produce gravitational wave memory. The gravitational wave memory produced by background including cosmic microwave background (CMB), cosmic neutrino background (CνB), and gravitational wave background is ...

The cosmic microwave background radiation
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 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.
