Oral Presentation

A Next Generation CFHT. I. The Science Case

Author(s): Patrick Cote

Presenter: Patrick Cote (Herzberg Institute of Astrophysics (NRC))

First light for the 3.6m Canada-France-Hawaii Telescope took place in 1979. Over its 30 year lifetime, the telescope has proven itself to be one of the world's most versatile astronomical research facilities, enabling its users to make fundamental contributions to a remarkably wide range of scientific topics. However, the astronomical landscape in 2010 is changing rapidly, and the telescope is facing increasingly stiff competition from newer, larger facilities that will place a strong emphasis on optical spectroscopy and/or wide-field imaging. We argue that the CFHT communities should consider an ambitious upgrade of the existing telescope: to a 10m-class facility with a wide-field, highly multiplexed, fiber spectrograph. We review the many science drivers motivating the development of such a facility, including (but not limited to) the study of dark energy and Galactic archaeology, and examine the proposed facility's benefits to the CFHT communities.
