(2008) First Season QUaD CMB Temperature and Polarization Power Spectra. Astrophysical Journal, 674 (1). pp. 22-28. ISSN 0004-637X AbstractQUaD is a bolometric CMB polarimeter sited at the South Pole, operating at frequencies of 100 and 150 GHz. In this
paper we report preliminary results fromthe first season of operation (austral winter 2005). All six CMB power spectra
are presented derived as cross spectra between the 100 and 150 GHz maps using 67 days of observation in a low foreground
region of approximately 60 deg2. These data are a small fraction of the data acquired to date. The measured
spectra are consistent with the ΛCDM cosmological model.We perform jackknife tests that indicate that the observed
signal has negligible contamination from instrumental systematics. In addition, by using a frequency jackknife we find
no evidence for foreground contamination. | Additional Information: | The original article is available at doi:10.1086/524922. QUaD is funded by the National Science Foundation in the
USA, through grants AST-0096778, ANT-0338138, ANT-
0338335, and ANT-0338238, by the Particle Physics and Astronomy
Research Council in the UK, and by the Science Foundation
Ireland. We would like to thank the staff of the Amundsen-Scott
South Pole Station and all involved in the United States Antarctic
Program for the superb support operation that makes the
science presented here possible. Special thanks go to our intrepid
winter-over scientist Robert Schwarz, who has spent three
consecutive winter seasons tending the QUaD experiment. The
BOOMERANG collaboration kindly allowed the use of their
CMB maps for our calibration purposes. M. L. B. acknowledges
