Design and characterization of the POLARBEAR-2b and POLARBEAR-2c cosmic microwave background cryogenic receivers
Logan Howe, Calvin Tsai, Lindsay Lowry +10
The POLARBEAR-2/Simons Array Cosmic Microwave Background (CMB) polarization experiment is an upgrade and expansion of the existing POLARBEAR-1 (PB-1) experiment, located in the Ata…
Evidence for the Cross-correlation between Cosmic Microwave Background Polarization Lensing from POLARBEAR and Cosmic Shear from Subaru Hyper Suprime-Cam
Toshiya Namikawa, Yuji Chinone, Hironao Miyatake +72
We present the first measurement of cross-correlation between the lensing potential, reconstructed from cosmic microwave background (CMB) {\it polarization} data, and the cosmic sh…
The Simons Observatory: Science goals and forecasts
The Simons Observatory Collaboration, Peter Ade, James Aguirre +247
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scient…
Picosecond Josephson Samplers: Modeling and Measurements
Logan Howe, Bart van Zeghbroeck, David Olaya +4
Measurement of signals generated by superconducting Josephson junction (JJ) circuits require ultra-fast components located in close proximity to the generating circuitry. We report…
Measurements of tropospheric ice clouds with a ground-based CMB polarization experiment, POLARBEAR
Satoru Takakura, Mario A. O. Aguilar-Faúndez, Yoshiki Akiba +45
The polarization of the atmosphere has been a long-standing concern for ground-based experiments targeting cosmic microwave background (CMB) polarization. Ice crystals in upper tro…
Performance of a continuously rotating half-wave plate on the POLARBEAR telescope
Satoru Takakura, Mario Aguilar, Yoshiki Akiba +50
A continuously rotating half-wave plate (CRHWP) is a promising tool to improve the sensitivity to large angular scales in cosmic microwave background (CMB) polarization measurement…
POLARBEAR Constraints on Cosmic Birefringence and Primordial Magnetic Fields
POLARBEAR Collaboration, Peter A. R. Ade, Kam Arnold +84
We constrain anisotropic cosmic birefringence using four-point correlations of even-parity -mode and odd-parity -mode polarization in the cosmic microwave background measurem…
Multi-stage Quantum Amplifier Readout Chain
Logan Howe, Andrea Giachero, Michael Vissers +5
Multi-stage cryogenic readout chains with a wide bandwidth and added noise within a few quanta of the quantum limit are frequently constructed using traveling-wave parametric ampli…
Compact Superconducting Kinetic Inductance Traveling Wave Parametric Amplifiers with On-chip rf Components
Logan Howe, Andrea Giachero, Michael Vissers +4
Quantum computing systems and fundamental physics experiments using superconducting technologies frequently require signal amplification chains operating near the quantum limit of…
Making maps of Cosmic Microwave Background polarization for B-mode studies: the POLARBEAR example
Davide Poletti, Giulio Fabbian, Maude Le Jeune +46
Analysis of cosmic microwave background (CMB) datasets typically requires some filtering of the raw time-ordered data. Filtering is frequently used to minimize the impact of low fr…
