Anisotropy in the Cosmic Microwave Background at Degree Angular Scales: Python V Results
Observations of the microwave sky using the Python telescope in its fifth season of operation at the Amundsen-Scott South Pole Station in Antarctica are presented. The system consists of a 0.75 m offaxis telescope instrumented with a HEMT amplifier-based radiometer having continuum sensitivity from 37-45 GHz in two frequency bands. With a 0.91 × 1.02 beam the instrument fully sampled 598 deg of...
متن کاملCosmic Microwave Background Anisotropy Measurement from Python V
We analyze observations of the microwave sky made with the Python experiment in its fifth year of operation at the Amundsen-Scott South Pole Station in Antarctica. After modeling the noise and constructing a map, we extract the cosmic signal from the data. We simultaneously estimate the angular power spectrum in eight bands ranging from large (‘ 40) to small (‘ 260) angular scales, with power d...
متن کاملA Limit on the Polarized Anisotropy of the Cosmic Microwave Background at Subdegree Angular Scales
A ground-based polarimeter, PIQUE, operating at 90 GHz has set a new limit on the magnitude of any polarized anisotropy in the cosmic microwave background. The combination of the scan strategy and full width half maximum beam of 0. 235 gives broad window functions with 〈lE〉 = 211 −146 and 〈lB〉 = 212 −135 for the Eand B-mode window functions, respectively. A joint likelihood analysis yields simu...
متن کاملNew Limits on the Polarized Anisotropy of the Cosmic Microwave Background at Subdegree Angular Scales
We update the limit from the 90 GHz Princeton IQU Experiment ground-based polarimeter on the magnitude of any polarized anisotropy of the cosmic microwave radiation. With a second year of data, we have now limited both Q and U on a ring of 1 radius. The window functions are broad: for E-mode polarization, the effective l is . We find that the E-mode signal can be no greater than 8.4 mK (95% CL)...
