Final design of SITELLE: a wide-field imaging Fourier transform spectrometer for the Canada-France-Hawaii Telescope
2012
We report here on the current status of SITELLE, an imaging Fourier transform spectrometer to be installed on the
Canada-France Hawaii Telescope in 2013. SITELLE is an Integral Field Unit (IFU) spectrograph capable of obtaining
the visible (350 nm – 900 nm) spectrum of every pixel of a 2k x 2k CCD imaging a field of view of 11 x 11 arcminutes,
with 100% spatial coverage and a spectral resolution ranging from R = 1 (deep panchromatic image) to R 4 (for gas
dynamics). SITELLE will cover a field of view 100 to 1000 times larger than traditional IFUs, such as GMOS-IFU on
Gemini or the upcoming MUSE on the VLT. SITELLE follows on the legacy of BEAR, an imaging conversion of the
CFHT FTS and the direct successor of SpIOMM, a similar instrument attached to the 1.6-m telescope of the
Observatoire du Mont-Megantic in Quebec. SITELLE will be used to study the structure and kinematics of HII regions
and ejecta around evolved stars in the Milky Way, emission-line stars in clusters, abundances in nearby gas-rich
galaxies, and the star formation rate in distant galaxies.
