SZ Simulation MBAC on ACT 1. 7’ beam w/ 2 X noise PLANCK Measure the primary anisotropy beyond the WMAP & Planck resolution limits. Find galaxy clusters at z<1 through SZ effect. Measure the amplitude of the CMB gravitational lensing, and therefore probe the mass power spectrum at 1 Mpc scales at z~1 -2. Detect signature of reonization at z~15 through Vishniac effect. Find all extragalactic mm-wave point sources in 100(o)2 to a sensitivity of 1 m. Jy. More info at http: //www. physics. upenn. edu/act Sensitivity/pixel ~ 2, 8 & 16 m. K (64 nights of quality data).
