Stellar feedback and star formation in Galactic high mass star forming regions

Star formation is an inefficient mechanism. Only a few per cent of the available gas in molecular clouds forms stars, leading to the observed low star formation rate. Stellar feedback is considered to be one of the major physical mechanisms to counteract the quick global collapse of molecular clouds. Young, massive stars influence their ambient medium through strong stellar winds and radiation. The outcome of this feedback depends on the number of massive stars in a region and also on the density of the ambient medium. In this talk, I will present our recent observational analysis on selected Galactic giant molecular clouds to understand the feedback mechanisms and its possible outcome on the subsequent star formation properties, such as, IMF, star formation efficiency and rate.
