Abstract: The recent finding that the integrated galactic initial stellar mass function, comprising all newly formed stars in all young star clusters, has, through its dependence on the star formation rate, a steeper slope in the high mass regime than the underlying canonical initial mass function of each star cluster individually offers new insights into the galactic star formation process. The classical linear relation between the star formation rate and the resultant Hα luminosity is broken and star formation rates are always underestimated. Our new relation is likely to lead to a revision of cosmological star formation history.
