Massive star formation in the central regions of spiral galaxies plays an important role in the dynamical and secular evolution of their hosts. Here, we summarise a number of recent investigations of the star formation history and the physical conditions of the gas in circumnuclear regions, to illustrate not only the detailed results one can

We present initial results from a survey of nearby AGN using the near infrared adaptive optics integral field spectrograph SINFONI. These data enable us to probe the distribution and kinematics of the gas and stars at spatial resolutions as small as 0.085”, corresponding in some cases to less than 10 pc. In this contribution we present results

We present stellar parameters and metallicities for a sample of 64 high metal content stars not known to harbor any planet. This sample provides the reference for investigating new correlations between stars and the existence of an orbiting planet.

We present ultraviolet to mid-infrared spectral energy distributions for a sample of 116 AGN in the Extended Groth Strip selected both in the X-rays and mid-infrared (96 with single detections and 20 with multiple optical counterparts). A complete set of different AGN types and starburst galaxy templates are used to fit the objects spectral energy
