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…
SPT-3G D1: A Measurement of Secondary Cosmic Microwave Background Anisotropy Power
P. Chaubal, N. Huang, C. L. Reichardt +104
The authors present new measurements of the small‑scale CMB temperature power spectrum from two years of SPT‑3G data, using 95, 150, and 220 GHz observations to constrain thermal a…
BICEP/Keck XXI: Constraints on Early-Universe Parity Violation from Multipole-Dependent Birefringence
Keck Collaboration, P. A. R. Ade, Zeeshan Ahmed +94
We present the first constraints on multipole-dependent cosmic birefringence using CMB polarization data from the BK18 dataset, which combines observations from BICEP2, Keck Array,…
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…
Characterization of the Polarization Beam Response of SPT-3G Using Point Sources
T. de Haan, M. Archipley, N. Huang +101
Precise measurements of cosmic microwave background (CMB) polarization require rigorous control of instrumental systematics. For the South Pole Telescope's third-generation camera…
