Abstract
We present a study correlating the spatial locations of young star clusters
with those of molecular clouds in NGC~5194, in order to investigate the
timescale over which clusters separate from their birth clouds. The star
cluster catalogues are from the Legacy ExtraGalactic UV Survey (LEGUS) and the
molecular clouds from the Plateau de Bure Interefrometer Arcsecond Whirpool
Survey (PAWS). We find that younger star clusters are spatially closer to
molecular clouds than older star clusters. The median ages for clusters
associated with clouds is 4~Myr whereas it is 50~Myr for clusters that are
sufficiently separated from a molecular cloud to be considered unassociated.
