Small Angular Scale Measurements of the CMB Temperature Power Spectrum from QUaD
Abstract
We present measurements of the cosmic microwave background (CMB) radiation temperature anisotropy in the multipole range $2000<\ell<3000$ from the QUaD telescope's second and third observing seasons. After masking the brightest point sources our results at 150 GHz are consistent with the primary $\Lambda$CDM expectation alone. We see no strong evidence of an SZ foreground, which is as expected for $\sigma_8 \approx 0.8$. We then predict the contribution of residual (un-masked) radio point sources using a model calibrated to our own bright source observations, and a full simulation of the source finding and masking procedure. Including this contribution makes a negligible difference at 150GHz and slightly improves the $\chi^2$ at 100 GHz.
