Title:Young massive stellar clusters in the Milky Way


Abstract:
The recent 2MASS and Spitzer/GLIMPSE surveys have revealed over a thousand candidate stellar clusters, 
which are hidden behind copious amounts of dust and gas in the Galactic plane. 
By combining multi-wavelenght information (near-, mid-infrared, radio and X data), it is possible to 
characterize  new candidate clusters, and to identify young massive clusters. Only a dozen massive 
(> 10^4 Msun) stellar clusters are currently known in the Milky Way.
We will present a multi-wavelength analysis of newly discovered massive  clusters,  and unveil their massive 
stellar content (Quartet, GLIMPSE9 and Cl1813-178 clusters). The clusters GLIMPSE9 and 
Cl1813-178  are also likely associated with supernovae remnants, therefore enabling us to estimate the 
masses of the supernovae progenitors.
