SPIDER Map-Making, CMB Polarization And Modeling Polarized Microwave Foreground Emission

Caroline Clark

December 06, 2012



Abstract: I will give a brief update on preparation for the SPIDER experiment, a suborbital polarimeter aimed at detecting B-mode polarization of the CMB. I will move on to present templates of the dominant Galactic foreground emissions, synchrotron and thermal dust. Given that foregrounds are expected to dominate the potential B-mode signal over all targeted observing frequencies, these templates may prove useful for studies of foreground contamination levels in patches targeted by experiments, testing component separation methods and constraining parameters in Galactic magnetic field models. I will confront the model with some available data, the WMAP full sky MCMC templates of foreground emission.
