First Maps from the Canadian Galactic Emission Mapper - An 8-10 GHz Northern Sky Polarization Survey
A weekly informal gathering of UCSB, LCO and KITP astrophysicists to hear about current research by locals and visitors.
Gravitational waves from cosmic inflation may have left a detectable signature in the parity-odd "B-mode" component of the polarization of the Cosmic Microwave Background (CMB). A detection of primordial B-modes would provide the strongest evidence for inflation up to date and would probe some of the highest-energy physics in the known universe. Current experiments have placed stringent upper limits on the signal, meaning that if B-modes are present, they are extremely faint and subdominant to polarized Galactic foregrounds at all frequencies. Mapping these foregrounds with high precision is therefore essential to any future detection. The Canadian Galactic Emission Mapper (CGEM) is a new 4-meter, single-dish, on-axis radio telescope at the Dominion Radio Astrophysical Observatory in British Columbia, mapping the Northern sky in polarization from 8–10 GHz with 0.5 degrees angular resolution. In this band, Galactic synchrotron emission is roughly 10³ times brighter than at CMB frequencies, allowing high signal-to-noise characterization of the foreground; the band also fills a gap between existing low-frequency surveys and WMAP/Planck, providing leverage on the synchrotron spectral index. In this talk, I will give an overview of CGEM's science goals and instrument design, and describe the data reduction and mapmaking pipeline we have developed. I will then present early maps of the Northern sky in both intensity and polarization, discuss what we have learned from them, and outline future plans for the experiment.
