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 showsthat the spinning dust hypothesis can explain the radio properties observed.. | | 出版日期 | Book 2016 | | 关键词 | Cosmic microwave background; Polarisation of the cosmic microwave background radiation; Anomalous Micr | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-26263-5 | | isbn_softcover | 978-3-319-79919-3 | | isbn_ebook | 978-3-319-26263-5Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer International Publishing Switzerland 2016 |
