Workshop; XII Annual Meeting, 2015, SOCHIAS; 2015

The star cluster group in University of Valparaiso is currentlycarrying out a further investigation of the population of open clusters in our Milky Way galaxy, by extending the current open cluster sample towards its highly obscured and central parts. This will allow us to gain unique insight into the formation, evolution, and dissipation of open clusters in the Galactic environment. In this poster we are focused on some very young stellar clusters (less than 5 Myr) and their connection with the surrounding environment. The stellar population is outlined using the deep infrared data from the VISTA Variables in the Vía Láctea (VVV) survey (Minniti el al 2010). On the other hand we are collecting literature data from existing all sky surveys such as MIPSGAL 24, GLIMPSE, Herschel, radio: HI SGPS data from the Australia Telescope Compact Array and the PMN survey made with the Parkes 64 m radio telescope, etc. and our own observations (APEX, future ALMA) in order to determine the properties of the ISM surrounding the clusters and to be able tocharacterize the molecular cloud kinematics and energetics.
