The interaction between a gas of ultra-cold bosonic atoms and a single Impurity is a prominent example of the interplay between few and many body physics. The impurity will deform the Bose gas locally, which can be described as the formation of a new quasiparticle, the Bose polaron. I will give a short overview about some of our recent findings on the properties of the polaron.
