Dark Energy Camera Dedication at the Cerro Tololo Inter-American Observatory

9 Nov 2012

DECam Dedication Ceremony with DES members


On November 9, 2012, ceremonies on the summit of Cerro Tololo, Chile marked the dedication of the Dark Energy Camera and the beginning of the 50th anniversary celebration of Cerro Tololo Inter-American Observatory (CTIO).

Speakers included Professor David Silva (NOAO Director), Professor Joshua Frieman (Director of the Dark Energy Survey) and Professor Ofer Lahav (UCL).

Professor Lahav talked at the event about the international perspective of DES, on behalf of the non-US partners: the UK, Spain, Brazil, Germany and Switzerland. He chairs the Science Committee of the Dark Energy Survey (DES), as well as the DES:UK consortium which, in addition to UCL, includes the universities of Portsmouth, Cambridge, Sussex, Edinburgh and Nottingham.

UCL has been involved in DES since its early days in 2004. UCL’ s Optical Science Laboratory, led by Dr Peter Doel, was responsible for putting together the Optical Corrector (supported by the STFC and universities funds). Drs Fillipe Abdalla and Sarah Bridle co-lead two of the Science Working Groups.

On 12 September 2012, the International Dark Energy Survey had its 'first light' with the $35 million Dark Energy Camera (DECam) at the CTIO Blanco 4-m telescope in Chile.

This was a great moment, after 8 years of preparation and UCL's involvement in instrumentation and science from the early days of the project. The optical corrector for the DES camera was assembled at UCL.
