The C-Band All-Sky Survey (C-BASS): Design and implementation of the northern receiver by King, O, Jones, M, Blackhurst, E, Copley, C, Davis, R, Dickinson, C, Holler, C, Irfan, M, John, J, Leahy, J, Leech, J, Muchovej, S, Pearson, T, Stevenson, M, Taylor, A

“…The northern component of the survey uses a broadband single-frequency analogue receiver fitted to a 6.1-m telescope at the Owens Valley Radio Observatory in California, USA. The receiver architecture combines a continuous-comparison radiometer and a correlation polarimeter in a single receiver for stable simultaneous measurement of both total intensity and linear polarization, using custom-designed analogue receiver components. …”

C-Band All-Sky Survey: a first look at the Galaxy by Irfan, M, Dickinson, C, Davies, R, Copley, C, Davis, R, Ferreira, P, Holler, C, Jonas, J, Jones, M, King, O, Leahy, J, Leech, J, Leitch, E, Muchovej, S, Pearson, T, Peel, M, Readhead, A, Stevenson, M, Sutton, D, Taylor, A, Zuntz, J

“… <p style="text-align:justify;"> We present an analysis of the diffuse emission at 5 GHz in the first quadrant of the Galactic plane using two months of preliminary intensity data taken with the C-Band All-Sky Survey (C-BASS) northern instrument at the Owens Valley Radio Observatory, California. Combining C-BASS maps with ancillary data tomake temperature-temperature plots, we find synchrotron spectral indices of β = -2.65 ± 0.05 between 0.408 and 5 GHz and β = -2.72 ± 0.09 between 1.420 and 5 GHz for -10° &gt; |b| &gt; -4°, 20° &gt; l &gt; 40°. …”
