Why Space in the Future • PSF Stability greatly increased with proper thermal environment & design • Space specific systematics being addressed • Near Infrared (NIR) coverage —Deeper survey —Photo-z’s • Lower background • Dark matter mapping (sensitive mostly to N eff )
Bullet Cluster Purple is dark matter Pink is X-ray emitting plasma Clowe, Bradac et al 2006. Due to the collision, the dominant baryonic component is in a different position than the total mass. Thus, most of the mass is dark matter.
