Abstract

We present a technical and scientific overview of SITELLE, an imaging Fourier transform spectrometer in the visible band installed at the Canada-France-Hawaii telescope, and highlight some of its most interesting results, from nearby nebulae to clusters of galaxies. SITELLE represents a total incongruity in the world of Fourier transform spectroscopy, being used in the visible range down to 350 nm, presenting a large field of view (11′′×11′′) and collecting more than four million spectra per data cube. Among its noteworthy achievements, SITELLE obtained the first realistic 3D views of the AT Cnc dwarf nova ejecta and of the Crab supernova remnant, a unique collection of emission line maps of a large sample of nearby galaxies, as well as the detection of ram pressure effects on star-forming galaxies in a cluster 3 billion light-years from us.
