A SITELLE overview of interacting galaxies and supernova remnants

The purpose of this talk, separated into three « chapters », is to present an overview of the capabilities of SITELLE, a wide-field imaging Fourier transform spectrometer built by our team and attached to the Canada-France-Hawaii telescope.

After a brief technical introduction to this instrument, I will summarize the collaborative work started a few years ago between IAA, Universidad de Granada and Université Laval on interacting galaxies (which is the main reason for my two-months sabbatical stay in Granada): Arp82, Arp 143 and, more recently, a sample of Hickson compact groups (a project led by Salvador Duarte Puertas, from UGR). The last chapter is dedicated to an ongoing work on supernova remnants, both in the Milky Way (the Crab Nebula and Cassiopeia A), and then in nearby galaxies, using data obtained as part of the SIGNALS survey.
