INFUSE

The Integral Field Ultraviolet Spectroscopic Experiment (INFUSE) aims to spectroscopically image the XA region of the Cygnus Loop supernova remnant, studying shock fronts as material from the supernova interacts with the interstellar medium. INFUSE will be the first far ultraviolet integral field spectrograph (IFS) in space and will have access to the Lyman ultraviolet (912 Å – 1216 Å). Lines in this bandpass trace low and medium velocity radiative shocks and high velocity non-radiative shocks. Observing these features at the arcsecond-scales made possible by the design of the INFUSE IFS will trace the full evolution of the shock features. INFUSE is projected to launch in 2023.
