The Cosmology Large Angular Scale Surveyor (CLASS) project aims to make a unique measurement of the Cosmic Microwave Background (CMB) that will transform our understanding of the universe and fundamental physics with far-reaching impacts on the scientific community, the next generation of scientists, and the public. As electromagnetic radiation, the CMB has both an intensity and a polarization, and it is the polarization of the CMB that CLASS will map over 70% of the sky. Key outcomes of CLASS are:
The CLASS telescopes are unique. We have developed new technologies that make CLASS stable and sensitive at a level necessary to achieve our science goals. The CLASS measurement strategy – mapping 70% of the sky with cross-checks against systematic errors from a premier site in the Atacama Desert of northern Chile – is also one-of-a-kind.
Further information about the science and technology of CLASS can be found under publications. In particular, general information suited to a public audience may be found on our Wikipedia page and in news articles by the Baltimore Sun and The Johns Hopkins News Network. An overview of the project more suited to professional scientists may be found in the latest CLASS summary paper.
