Observational Cosmology at the University of Wisconsin-Madison

We specialize in the development and deployment of instruments capable of reaching the exquisite levels of sensitivity necessary to detect the very weak microwave signals constituting the Cosmic Microwave Background.

We accomplish this by developing novel detectors using optical design cryogenics and microlectrotronics. Simulation techniques are employed to determine the extent to which our measurements assist in constraining cosmological models.
