STAGES > about STAGES


STAGES galaxyThe 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.


STAGES galaxiesThe 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 the structure.

Our survey goals include simultaneously linking galaxy morphology with other observables such as age, star-formation rate, nuclear activity, and stellar mass.




STAGES galaxiesIn 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.
