STAGES > about STAGES
Space Telescope A901/902 Galaxy Evolution Survey (aka STAGES) is a
multiwavelength project designed to probe the physical drivers of
galaxy evolution across a wide range of environments and luminosity.
The STAGES team
has obtained observations of a complex multiple-cluster system
at z=0.16 ranging from the X-ray to the radio, including an 80-orbit
Hubble Space Telescope mosaic covering the full 0.5x0.5 degree span of
Our survey goals include simultaneously linking galaxy morphology with
other observables such as age, star-formation rate, nuclear activity,
and stellar mass.
In addition, with the unique multiwavelength dataset
and new high resolution mass maps from gravitational lensing
, we are able to disentangle the large-scale structure of the supercluster.
By examining all aspects of environment, we aim to determine the
relative importance of the dark matter halos, the local galaxy density,
and the hot X-ray gas in driving galaxy transformation.
We acknowledge support from HST grant GO-10395.
