Dr Reichardt’s research utilises international experiments to study the Cosmic Microwave Background, relic radiation from the Big Bang. He is a key member in the international collaborations for the South Pole Telescope (with the experiments SPT-SZ, SPTpol, and SPT-3G), and the POLARBEAR and Simons Array experiments.

Members of his group are using data from these world class observatories to address some of the big problems in cosmology today: (1) using galaxy clusters, the most massive collapsed objects in the Universe, to study dark energy, (2) using the gravitational lensing of the cosmic microwave background to measure just how massive neutrinos are, and, perhaps most excitingly, (3) looking for the gravitational waves, the so-called “smoking gun” for an inflationary epoch in the first instant of the Universe.
