WebIn this final Lambda Lab #3 you get to model the CMB power spectrum with CAMB - the new version of the famous CMBFAST by Seljak and Zaldarriaga (also known as the fastest Boltzman code in the west), now available on line, in real time. For background reading, refer back to the Introduction page, where you will find several good articles on ... WebCMBFAST. The solutions for the intensity are given in the 1]3 covariant formalism in Challinor & Lasenby (1999), Challinor(1999b),andGebbieetal.(1999);solutionsforthe polarization are given in Challinor (1999c). Equivalent results in the total angular momentum formalism are given in Hu et al. (1998). The present-day multipoles are obtained

Basically, the conformal time is equal to the distance of the particle horizon, divided by c (see this post for more info). η 0 refers to the current conformal age of the universe.
WebCMBFAST has become the "industry standard" for computing CMB power spectra, polarization, and transfer functions. It uses a method based on integration over the sources along the photon past light cone, in which the temperature anisotropy is written as a time integral over the product of a geometrical term and a source term. This method allows ...
