Professor of Physics
Faculty Research Interests
Cosmic Microwave Background Radiation

Sarah's group builds instrumentation to observe the Cosmic Microwave Background radiation (CMB) at millimetre wavelengths. The CMB is a virtually pristine relic of conditions in the universe approximately 400,000 years after the Big Bang and by studying it we can test our understanding of the laws of physics in the extreme conditions that occurred in the first few moments after the Big Bang. Sarah's group use telescopes located at the best sites in the world for millimetre wavelength astronomy, including the South Pole, the Chilean Andes, and Mauna Kea in Hawaii.
