While the arcminute-scale Cosmic Microwave Background (CMB) anisotropies aredue to secondary effects, point sources dominate the total anisotropy powerspectrum. At high frequencies the point sources are primarily in the form ofdusty, star-forming galaxies. Both Herschel and Planck have recently measuredthe anisotropy power spectrum of cosmic infrared background (CIB) generated bydusty, star-forming galaxies from degree to sub-arcminute angular scales,including the non-linear clustering of these galaxies at multipoles of 3000 to6000 relevant to CMB secondary anisotropy studies. We scale the CIB angularpower spectra to CMB frequencies and interpret the combined WMAP-7 year andarcminute-scale Atacama Cosmology Telescope (ACT) and South Pole Telescope(SPT) CMB power spectra measurements to constrain the Sunyaev-Zel'dovich (SZ)effects. Allowing the CIB clustering amplitude to vary, we constrain theamplitudes of thermal and kinetic SZ power spectra at 150 GHz.
