The nature of nuclear stellar disks

Small and bright stellar disks with scalelengths of few tens of parsec are known to reside in the center of galaxies. Despite the attention they received in the last years, the processes responsible of their formation are not completely understood and still under debate. Unveiling the formation processes of these structure is important since they constrain the formation and evolution of the host galaxy. Furthermore, nuclear stellar disks are among the smallest structures known to reside in the center of galaxies and together with black holes and nuclear clusters they are crucial to infer clues on the coevolution between the galaxy and its nucleus.
