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…

Design and Performance of 220 and 270 GHz Bandpass Filters for BICEP Array

A. Steiger, The BICEP/Keck Collaboration, P. A. R. Ade +90

The BICEP Array (BA) is the latest in the BICEP/ Keck series of experiments that aim to measure the polarization of the cosmic microwave background (CMB) with small aperture polari…

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…

Measurement of the Full Shape of the Thermal Sunyaev-Zeldovich Power Spectrum from South Pole Telescope and {\it Herschel}-SPIRE Observations

S. Raghunathan, P. A. R. Ade, D. Anbajagane +139

We present a measurement of the full shape of the power spectrum of the thermal Sunyaev-Zeldovich (tSZ) effect down to arcminute scales using cosmic microwave background (CMB) data…

Improved Absolute Polarization Calibrator for BICEP CMB Polarimeters

A. R. Polish, P. A. R. Ade, Z. Ahmed +89

Cosmic birefringence is a hypothesized parity violation in electromagnetism that predicts a frequency-independent polarization rotation as light propagates. This would rotate the l…
