The Cosmic Microave Background (CMB) is often described as the Rosetta Stone of cosmology, linking the early and late universe. The Atacama Cosmology Telescope measures the CMB radiation from the Atacama Desert, to a resolution of 1 arcminute, which allows us to measure fluctuations in the temperature of the CMB to much smaller scales. I am involved in the analysis and tests of the ACT power spectrum, and the constraints on cosmological parameters from CMB lensing of the ACT data.
