Current status of the QUaD 1st season analysis

By A. Orlando, E. Y. S. Wu and M. Zemcov


Abstract. I describe the current status of the analysis of the 1st season’s data taken with the QUaD Cosmic Microwave Background (CMB) polarisation telescope. QUaD is a CMB polarisation bolometer-array telescope. The instrument was installed at the South Pole over the 2004-05 Austral Summer and completed its first season of observations during the 2005 Austral Winter. The analysis of these data is in an advanced state and initial results look promising. In this proceedings, I give a brief summary of the telescope and data analysis pipeline, and present the 100 GHz and 150 GHz temperature and polarisation maps from the 1st year data. I also describe our power spectrum estimation methodology and indicate the expected CMB power spectra constraints obtainable from the 1st year data, as measured from simulations. 1
