Development of TIFUUN: Terahertz Integral Field Units with Universal Nanotechnology
Akira Endo, Tom J. L. C. Bakx, Jochem J. A. Baselmans +50
TIFUUN (THz Integral Field Units with Universal Nanotechnology) is an ultra-wideband mm-submm wave imaging spectrometer that capitalizes on the highly scalable integrated supercond…
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…
Design and Performance of 30/40 GHz Diplexed Focal Plane for BICEP Array
Corwin Shiu, Ahmed Soliman, Roger O'Brient +11
We demonstrate a wide-band diplexed focal plane suitable for observing low-frequency foregrounds that are important for cosmic microwave background polarimetry. The antenna element…
