PROJECT 1


Circumnuclear Rings in Nearby Galaxies
(M. Pastoriza)

Determine the star formation History of the Circumnuclear rings of
nearby spiral galaxies and the process of  Star Cluster Formation  in 
dense and heavy-element abundance  environment , from   the  study 
of the the  Super Star Cluster detected in their  HII regions.

Required Observations:

IR and optical spectroscopy complemented with optical  (UBVRI) and IR (HK) 
images of the star forming-complex.
