Description
The 10m South Pole Telescope (SPT) maps the CMB sky with arc-minute resolution. With its high sensitivity observations at 95, 150 and 220GHz its third generation camera (SPT-3G) aims at providing unprecedented constraints on the cosmological parameters, hopefully soon to be based on the analyses of 10% of the CMB sky.
The South Pole Observatory combines the SPT observations with those of the BICEP array, focused on the detection of polarisation B modes at large scales, a signature of the gravitational waves generated by an early phase of inflation.
This talk will provide a status report of these projects.
