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…

The SPT-3G+ receiver design

H. Athreya, Z. Ahmed, J. E. Austermann +71

We present the thermo-mechanical design of the cryostat and camera optics for SPT-3G+, a new receiver being developed for the South Pole Telescope (SPT). The receiver consists of 1…

Setting requirements on out-of-band rejection for next-generation CMB experiments. Application to the LiteBIRD instrument

L. Mousset, L. Montier, J. Aumont +15

Next-generation cosmic microwave background experiments have very stringent constraints to achieve the required sensitivity to target polarization modes. In this work, we inten…

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,…

Calibration Measurements of the BICEP3 and BICEP Array CMB Polarimeters from 2017 to 2024

Christos Giannakopoulos, Clara Vergès, P. A. R. Ade +83

The BICEP3 and BICEP Array polarimeters are small-aperture refracting telescopes located at the South Pole designed to measure primordial gravitational wave signatures in the Cosmi…
