Data from Clusters in the UV as Engines (CLUES)

CLUES is an HST medium-size program (ID 15627, PI: Adamo) that provides FUV spectroscopy of 20 young star clusters in local galaxies (less than 16 Mpc away). Three sources (NGC4449-YSC1, NGC5253-YSC1 and NGC5253-YSC2) were observed as part of an earlier program (ID 11579, PI: Aloisi). All the CLUES star clusters are very young (<50 Myr) and massive (> 104 Msun) and they are hosted in galaxies that are part of the Hubble treasury program Legacy ExtraGalactic Uv Survey (LEGUS, Calzetti 2015). The team has selected in most cases two clusters per galaxy, at various distances from the center of the galaxy (from 0.1 to 2.8 half-mass radii). The main goals of this project are: (1) derive the stellar population properties of young clusters using FUV spectroscopy, including a measurement of the feedback from stellar winds and supernovae; (2) measure the kinematics of the outflowing gas by modeling the ISM absorption lines in the FUV and connect this to the stellar feedback injected by individual young star clusters.
