Clarence L. Chang Associate Professor, Department of Astronomy and Astrophysics Education: Ph.D., Stanford University, 2005 Phone: (773) 702-7840 Location: ERC 333 Email: clchang ![]() Affiliations: Kavli Institute for Cosmological Physics Research Upper right: Picture of the South Pole Telescope. Publications: ADS | arXiv | inSPIREUpper left: a Transition Edge Sensor fabricated at Argonne National Laboratory. Lower right: the SPTpol focal plane. Lower left: a plot of the first detection of CMB B-mode polarization. This signal is the result of gravitational lensing of the CMB. Research Fields: Clarence's interests focus on observational cosmology with a particular emphasis on developing new superconducting technology for use in new experiments. He is part of a joint Chicago/Argonne superconducting detector development collaboration which will develop and build the focal plane for the upcoming SPT-3G experiment. This focal plane, with over 15,000 polarization sensitive detectors, will enable the South Pole Telescope to observe 2500 square degrees with unprecedented sensitivity. SPT-3G will explore the physics of inflation, dark energy, and the cosmic neutrino background. Member of Research Groups: Teaching Courses Past courses:
