Raymond G. Carlberg

Raymond Carlberg’s main interests are observational cosmology and telescope design and construction. He was the principal investigator of the Canadian Network for Observational Cosmology cluster and field galaxy surveys, and helped lead the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS). The Supernova Legacy Survey, a component of the CFHTLS, made the first accurate measurement of the dark energy equation of state parameter. Carlberg was the PI of awards from NSERC and CFI which enabled Canadian participation in the development of Extremely Large Telescope designs and partnership within the Thirty Meter Telescope project, a joint effort of the astronomy community and industrial interests in Canada. In April 2015, the Government of Canada announced a commitment of $243.5 million towards the construction of the TMT. A smaller scale effort is under way to develop the unique capabilities of Ellesmere Island as a high quality observatory site within Canada.
