We present preliminary results of a photometric investigation on IC10 using F555W and F814W data collected with WFPC2@HST covering two different regions. We provide a new estimate of both distance and reddening by adopting the Tip of the Red Giant Branch (TRGB). We find that the RGB stars in the two regions are located at the same distance, but

The understanding of complex stellar populations and their star formation histories relies on the stellar evolution theory as much as the improvement of our knowledge of the stellar evolution relies on the study of stellar populations. In this context, testing stellar evolution models is fundamental to properly evaluate the reliability of the

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
