Scientific paper

The C-Band All-Sky Survey (C-BASS) is a project that aims to produce sensitive, all-sky maps of Galactic synchrotron emission at 5 GHz in total intensity and linear polarization. These measurements will be used primarily in the subtraction of foregrounds from measurements of the polarized Cosmic Microwave Background. Secondary scientific goals include studying the nature of the Galactic magnetic field, constraining the Galactic cosmic ray energy spectrum, and constraining low frequency foregrounds including anomalous microwave emission. Measurements will be performed using a 6 m dish at the Owens Valley Radio Observatory (OVRO) in California, and a 7 m dish in the new Radio Astronomy Park near Carnarvon, South Africa. The Northern hemisphere observations are underway, the Southern instrument is complete, and deployment of the Southern receiver is planned for early 2012. We discuss the progress of the survey observations, present a preview of the Northern hemisphere data, and discuss the performance of the instrument.
The C-BASS project is a collaboration between Caltech/JPL in the US, Oxford and Manchester Universities in the UK, KACST in Saudi Arabia, and Rhodes University and the Hartebeesthoek Radio Astronomy Observatory in South Africa. It is funded by the NSF (AST-0607857) and the participating institutions.
