SMALL ANGULAR SCALE MEASUREMENTS OF THE COSMIC MICROWAVE BACKGROUND TEMPERATURE POWER SPECTRUM FROM QUaD

Abstract

We present measurements of the cosmic microwave background (CMB) radiation temperature anisotropy in the
\nmultipole range 2000 < < 3000 from the QUaD telescope’s second and third observing seasons. After masking
\nthe brightest point sources our results are consistent with the primary ΛCDM expectation alone. We estimate
\nthe contribution of residual (un-masked) radio point sources using a model calibrated to our own bright source
\nobservations, and a full simulation of the source finding and masking procedure. Including this contribution slightly
\nimproves the χ2. We also fit a standard Sunyaev–Zel’dovich (SZ) template to the bandpowers and see no strong
\nevidence of an SZ contribution, which is as expected for σ8 ≈ 0.8.
