Webmation content of the CMB and ways of thinking about the cosmological constraints that can be derived from it. Tegmark et al. (2006, Phys Rev D, 74, 123507) is one of the best discussions on joint cos-mological constraints from CMB anisotropy and galaxy large scale structure, from WMAP and the SDSS, respectively. WebThe search for the curl component (B mode) in the cosmic microwave background (CMB) polarization induced by inflationary gravitational waves is described. The canonical single-field slow-roll model of inflation is presented, and we explain the quantum production of primordial density perturbations and gravitational waves. It is shown how these …
