We present measurements of the cosmic microwave background (CMB) radiation temperature anisotropy in the multipole range 2000 << 3000 from the QUaD telescope’s second and third observing seasons. After masking the brightest point sources our results are consistent with the primary ΛCDM expectation alone. We estimate 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 slightly improves the χ2. We also fit a standard Sunyaev–Zel’dovich (SZ) template to the bandpowers and see no strong evidence of an SZ contribution, which is as expected for σ8 ≈ 0.8.Other Sources
