"Echoes of supernova explosions are a spectacular and valuable phenomenon in astronomy. The reflected light contains spectral information from the explosion and allows precise characterization of the supernova, even if it already appened several hundred years ago. The echo also contains information about the reflecting and emitting dust, enabling detailed studies on the physics of pristine interstellar material. This work focuses on three topics within this framework of supernova explosions, their light echoes and the interstellar medium. First, I use optical and infrared surveys to identify echoes from supernovae. While the search for scattered light echoes from Kepler’s supernova proved unsuccessful until now, I developed a new approach to systematically search for infrared echoes using WISE data. This new technique allows the identification of light echo candidates from several historical supernova remnants. The echoing material could be associated with the densest parts of the cold neutral medium. A comparisons with theoretical studies reveals the fractal structure of the interstellar medium and its underlying turbulent flows. Finally, I concentrate on the dust content of Cassiopeia A. With the aid of new far infrared data, an unshocked dust component is identified within the reverse shock region of the remnant. These observations confirm that Type IIb supernovae initially produce dust, but directly show their mechanism and efficiency of dust destruction."^^ . "2012" . . . . . . . . "Marc-André"^^ .
