This extensive thesis work covers several topics, including
intensity and polarization, focusing on a new polarization bias
reduction method. Vidal studied data from the WMAP satellite, which
is low signal-to-noise and as such has to be corrected for
polarization bias. He presents a new method for correcting the
data, based on knowledge of the underlying angle of polarization.
Using this novel method, he sets upper limits for the polarization
fraction of regions known to emit significant amounts of spinning
dust emissions. He also studies the large-scale loops and filaments
that dominate the synchrotron sky. The dominant features are
investigated, including identification of several new features. For
the North Polar Spur, a model of an expanding shell in the vicinity
of the Sun is tested, which appears to fit the data. Implications
for CMB polarization surveys are also discussed. In addition, Vidal
presents interferometric observations of the dark cloud LDN 1780 at
31 GHz and shows that the spinning dust hypothesis can explain the
radio properties observed.
