Comparing and combining the Saskatoon, QMAP and COBE CMB maps
Yongzhong Xu, Max Tegmark, Angelica de Oliveira-Costa +5
We present a method for comparing and combining maps with different resolutions and beam shapes, and apply it to the Saskatoon, QMAP and COBE/DMR data sets. Although the Saskatoon…
Galactic contamination in the QMAP experiment
Angelica de Oliveira-Costa, Max Tegmark, Mark J. Devlin +6
We quantify the level of foreground contamination in the QMAP Cosmic Microwave Background (CMB) data with two objectives: (a) measuring the level to which the QMAP power spectrum m…
Characterizing the Peak in the CMB Angular Power Spectrum
Lloyd Knox, Lyman Page
A peak has been unambiguously detected in the cosmic microwave background (CMB) angular spectrum. Here we characterize its properties with fits to phenomenological models. We find…
