"What lies in the shadows … no more! The MUSE view of SNR E0102 in the SMC"

1E0102.2-7219 (E0102 for short) is one of the handful of known oxygen-dominated, young supernova remnants. These systems, caught only a few 1000 years after the SN explosion of a massive star, display fast moving (a few 1000 km/s), oxygen-bright, hydrogen-poor filaments visible at optical wavelengths: the outer-layers of the progenitor star, expelled during the SN explosion, and (still) expanding ballistically. In this talk, I will present recent observations of E0102 with the MUSE optical integral field spectrograph at the VLT. I will describe both the original motivation for these observations — namely the first detection of Sulfur lines from the fast ejecta with the WiFeS integral field spectrograph - as well as the exciting and unanticipated discoveries that were found lurking in the MUSE datacube.
