An introduction to map-making for CMB experiments

Year: 2024

Type: conference-paper

Abstract: The cosmic microwave background (CMB) anisotropies are a powerful probe of the early universe, and have largely contributed to establishing the current standard cosmological model. To extract the information encoded in those tiny variations, one must first compress the raw, time-domain data collected by a telescope into maps of the sky at the observed frequencies, in a procedure known as map-making. I provide a general introduction to this problem, and highlight a few specificities of the MAPPRAISER implementation.
