Measuring Cmb Polarization with Quiet: the Q/u Imaging Experiment
نویسنده
چکیده
Phase I of the Q/U Imaging ExperimenT (QUIET) measures the Cosmic Microwave Background polarization anisotropy spectrum at angular scales 25 . l . 1000. QUIET has deployed two independent receiver arrays. The 40-GHz array took data between October 2008 and June 2009. The 90-GHz array was deployed in June 2009 and observations are ongoing. Described in this proceeding are the instrument, analysis procedures, and expected science reach for the QUIET Phase I arrays. We also briefly discuss the science forecasts for QUIET Phase II in which arrays roughly an order-of-magnitude larger will be deployed.

Quiet - Measuring the Cmb Polarization with Coherent Detector Arrays
The footprint of inflation in the polarization pattern of the CMB is expected at more than an order of magnitude below the limits of current polarization measurements. Large receiver arrays are mandatory for achieving the required sensitivity. We describe here the approach of the Q/U Imaging ExperimenT (QUIET) which will use coherent detector arrays. Pseudocorrelation receivers have been produc...
متن کاملCoherent polarimeter modules for the QUIET experiment
The Q/U Imaging Experiment (QUIET) is an experimental program to make very sensitive measurements of the Cosmic Background Radiation (CMB) polarization from the ground. A key component of this project is the ability to produce large numbers of detectors in order to achieve the required sensitivity. Using a breakthrough in mm-wave packaging at JPL, a polarimeter-on-a-chip has been developed whic...

Beam characterization is of critical importance when analyzing and interpreting data from Cosmic Microwave Background (CMB) experiments. In this paper we present scanning strategies, data analysis methods and results of the 44 GHz (Q-Band) beam characterization for the Q/U Imaging ExperimenT (QUIET) PhaseI, using the Crab nebula (Tau A) and Jupiter as polarized and unpolarized point sources, re...
متن کاملPolarized wavelets and curvelets on the sphere
The statistics of the temperature anisotropies in the primordial cosmic microwave background radiation field provide a wealth of information for cosmology and for estimating cosmological parameters. An even more acute inference should stem from the study of maps of the polarization state of the CMB radiation. Measuring the extremely weak CMB polarization signal requires very sensitive instrumen...
متن کاملMeasuring the Cosmic Microwave Background Radiation (CMBR) polarization with QUIET
— A major goal of upcoming experiments measuring the Cosmic Microwave Background Radiation (CMBR) is to reveal the subtle signature of inflation in the polarization pattern which requires unprecedented sensitivity and control of systematics. Since the sensitivity of single receivers has reached fundamental limits future experiments will take advantage of large receiver arrays in order to signif...
