In collaboration with the team of Ulrich Kuhl in Nice and with Dorian Bouchet in Grenoble, we published an article in Nature Physics that demonstrates how the information that waves acquire about an object flows from this object to an outside observer. From our group Jakob Hüpfl, Felix Russo and Lukas Rachbauer were principally involved in this study – congratulations!
