High-sensitivity measurements of the cosmic microwave background power spectrum with the extended Very Small Array
We present deep Ka-band (ν~ 33 GHz) observations of the cosmic microwave background (CMB) made with the extended Very Small Array (VSA). This configuration produces a naturally weighted synthesized FWHM beamwidth of ~11 arcmin, which covers an l range of 300 to 1500. On these scales, foreground extragalactic sources can be a major source of
