Performance of a 4 Kelvin pulse-tube cooled cryostat with dc SQUID amplifiers for bolometric detector testing
Darcy Barron, Matt Atlas, Brian Keating +3
The latest generation of cosmic microwave background (CMB) telescopes is searching for the undetected faint signature of gravitational waves from inflation in the polarized signal…
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…
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…
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…
Galactic foreground contribution to the BEAST CMB Anisotropy Maps
Jorge MejÃa, Marco Bersanelli, Carlo Burigana +17
We report limits on the Galactic foreground emission contribution to the Background Emission Anisotropy Scanning Telescope (BEAST) Ka- and Q-band CMB anisotropy maps. We estimate t…
High quality superconducting tunnel junction barriers using atomic layer deposition
Stephanie M. Moyerman, Guangyuan Feng, Lisa Krayer +2
We demonstrate a technique for creating high quality, large area tunnel junction barriers for normal-insulating- superconducting or superconducting-insulating-superconducting tunne…
