Abstract

Kinematic and population studies show that bulges are generally rotationally flattened systems similar to low-luminosity ellipticals. However, observations with state-of-the-art integral field spectrographs, such as SAURON, indicate that the situation is much more complex, and allow us to investigate phenomena such as triaxiality, kinematic decoupling and population substructure, and to study their connection to current formation and evolution scenarios for bulges of early-type galaxies. We present the examples of two SO bulges from galaxies in our sample of nearby galaxies: one that shows all the properties expected from classical bulges (NGC 5866), and another case that presents kinematic features appropriate for barred disk galaxies (NGC 7332).
