Overview and status of BICEP Array's BA4-90/150 CMB polarimeter

M. A. Petroff, P. A. R. Ade, Z. Ahmed +83

The inflation paradigm postulates a period of rapid expansion in the early Universe, which would generate gravitational waves. These tensor perturbations would produce a faint B-mo…

Controlling instrumental systematics for the BICEP inflation survey

C. Vergès, P. A. R. Ade, Z. Ahmed +92

The BICEP series of experiments has been observing CMB polarisation from the South Pole for over 20 years, with the goal of constraining inflationary gravitational waves. The upcom…

The South Pole Telescope AGN Monitoring Campaign: First Release of SPTpol Bright AGN Light Curves

J. C. Hood, P. A. R. Ade, A. J. Anderson +66

The South Pole Telescope (SPT) collaboration has recently embarked upon a campaign to monitor the brightness of a sample of active galactic nuclei (AGN), both in real time and in a…
