LEGUS Survey
Survey Description
LEGUS (Legacy ExtraGalactic UV Survey) is a Treasury Program that will image 50
local (closer than 12 Mpc) galaxies in multiple colours with WFC3 and ACS. Because of the
proximity of all targets, the galaxies will be resolved into their main components: stars, star clusters,
and associations.
Survey Science Goals
The observations will be used to accomplish the main science goals of LEGUS:
(1) quantify how the clustering of star formation evolves both in space and time,
(2) discriminate among models of star cluster evolution,
(3) investigate the effects of SFH on the UV SFR calibrations,
(4) explore the impacts of environment on star formation and cluster evolution across the full range of galactic and ISM properties,
(5) investigate UV-excess globular clusters across multiple environments,
(6) study the environment surrounding supernovae.
