The cosmic microwave background radiation.
Radio Astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe. This paper is about the discovery of the cosmic microwave background radiati...
متن کاملThe Cosmic Microwave Background Radiation
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. We discuss the theoretical origins of these an...
متن کاملThe Cosmic Microwave Background Radiation
These lectures will attempt to convey the excitement and promise in studies of the microwave radiation left over from the early universe. They are aimed at an audience of experimental high energy physicists. The first lecture will concentrate on how the radiation is characterized, how it and its anisotropies are generated, and the physics that it reveals. The second lecture will concentrate on ...
متن کاملPolarization of the Cosmic Microwave Background Radiation
The CMB radiation is completely characterized by its temperature anisotropy and polarization in each direction in the sky. Today, studies of the temperature anisotropies in the CMB have provided strong constraints on many of the cosmological parameters. However, for precision cosmology we still need to consider the polarization information of the CMB to break some of the degenerecies that exist...
متن کاملMultiscaling of cosmic microwave background radiation
The multiscaling features of structure functions of cosmic microwave background (CMB) radiation have been studied using the new data available with the resolution of the order of a degree (combined QMAP and Saskatoon CMB radiation maps). It is shown that the scaling exponents of the CMB structure functions in the angular scale interval 0.9–4◦ are nearly identical to those of universal velocity ...
