BICEP/Keck XXII: Analysis of the South Pole Atmosphere for CMB Observations

P. A. R. Ade, Z. Ahmed, M. Amiri +92

The South Pole is among the driest sites on Earth, and the resulting high atmospheric transparency makes it an excellent site for millimeter-wave astronomical observations. Neverth…

Status of BICEP Array and Integration of the 220/270 GHz Receiver

A. Steiger, P. A. R. Ade, Z. Ahmed +83

Measurements of the polarization of the cosmic microwave background are critical for modern cosmology as they constrain the physics of the early universe and cosmic inflation. BICE…

Quantifying the systematic impact of differential beam response on the BICEP CMB polarization data from 2016 through 2024

B. D. Elwood, P. A. R. Ade, Z. Ahmed +83

As cosmic microwave background (CMB) polarization experiments, including BICEP3, BICEP Array, and future BICEP experiments, achieve ever-deeper polarization maps in search of primo…

Optics and broadband anti-reflection coatings for the BA4-90/150 receiver

A. R. Polish, P. A. R. Ade, Z. Ahmed +84

The BICEP Array telescopes search for primordial B-mode polarization from inflationary gravitational waves. This signal is exceedingly faint, demanding excellent map depth and syst…

Optical characterization of the BICEP array 150 and 220/270GHz CMB polarimeters in the 2026 season

M. Izquierdo Poza, P. A. R. Ade, Z. Ahmed +82

BICEP Array (BA) is the current-generation instrument in the BICEP series of small-aperture, on-axis refracting telescopes at the South Pole, designed to constrain the tensor-to-sc…

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…

A material-agnostic platform to probe spin-phonon interactions using high-overtone bulk acoustic wave resonators

Q. Greffe, A. Hugot, S. Zhang +6

Spin-phonon interactions have a dual role in emerging spin-based quantum technologies. While they can be a limitation to device performance through decoherence, they also serve as…

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…

BICEP/Keck XX: Component-separated maps of polarized CMB and thermal dust emission using Planck and BICEP/Keck Observations through the 2018 Observing Season

Keck Collaboration, P. A. R. Ade, Z. Ahmed +94

We present component-separated polarization maps of the cosmic microwave background (CMB) and Galactic thermal dust emission, derived using data from the BICEP/Keck experiments thr…

BICEP/Keck XVIII: Measurement of BICEP3 polarization angles and consequences for constraining cosmic birefringence and inflation

Keck Collaboration, P. A. R. Ade, Z. Ahmed +83

We use a custom-made calibrator to measure individual detectors' polarization angles of BICEP3, a small aperture telescope observing the cosmic microwave background (CMB) at 95GHz…

BICEP / Keck XVII: Line of Sight Distortion Analysis: Estimates of Gravitational Lensing, Anisotropic Cosmic Birefringence, Patchy Reionization, and Systematic Errors

Keck Collaboration, P. A. R. Ade, Z. Ahmed +91

We present estimates of line-of-sight distortion fields derived from the 95 GHz and 150 GHz data taken by BICEP2, BICEP3, and Keck Array up to the 2018 observing season, leading to…

BICEP / Keck XVI: Characterizing Dust Polarization through Correlations with Neutral Hydrogen

Keck Collaboration, P. A. R. Ade, Z. Ahmed +92

We characterize Galactic dust filaments by correlating BICEP/Keck and Planck data with polarization templates based on neutral hydrogen (H I) observations. Dust polarization is imp…
