Summary<br />
✴ STAGES is a multi-wavelength survey of <strong>the</strong> <strong>Abell</strong> <strong>901</strong>/<strong>902</strong><br />
supercluster.<br />
✴ The survey aims to dist<strong>in</strong>guish between <strong>the</strong> different physical<br />
mechanisms which drive galaxy evolution <strong>in</strong> dense environments.<br />
✴ Weak lens<strong>in</strong>g analysis of HST images permits high resolution<br />
dark matter “observations”.<br />
✴ Old Red <strong>Galaxies</strong> trace <strong>the</strong> underly<strong>in</strong>g dark matter distribution<br />
✴ Intermediate density regions key site for galaxy transformations<br />
✴ Current work br<strong>in</strong>g<strong>in</strong>g toge<strong>the</strong>r all different multi-wavelength<br />
cluster <strong>in</strong>formation to form a coherent underst<strong>and</strong><strong>in</strong>g of <strong>the</strong><br />
violent history of this supercluster<br />
