BICEP1 is a millimeter-wavelength telescope designed specifically to measure the inflationary B-mode polarization of the Cosmic Microwave Background (CMB) at degree angular scales. We present results from an analysis of the data acquired during three seasons of observations at the South Pole (2006 to 2008). This work extends the two-year result published in Chiang et al. (2010), with additional...

In this paper we show how effects from small scales can enter the angular-redshift power spectrum $C_\ell(z,z')$. particular, that spectroscopic surveys with high redshift resolution are already affected on large angular scales, i.e. at low multipoles, by features scales. When considering resolution, it is therefore important to account for non-linearities relevant even multipoles. This may als...
