Engineering of titanium transition edge sensor wafers for the BA4-90/150 receiver of BICEP Array
A. Patel, P. A. R. Ade, Z. Ahmed +83
BA4-90/150, the fourth receiver to be deployed in the BICEP Array (BA) series, is a dichroic 90/150 GHz instrument targeting the frequency space where sensitivity to the CMB polari…
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…
The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes
The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479
We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…
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…
Demonstration of a 1820 channel multiplexer for transition-edge sensor bolometers
J. C. Groh, Z. Ahmed, J. Austermann +16
The scalability of most transition-edge sensor arrays is limited by the multiplexing technology which combines their signals over a reduced number of wires and amplifiers. In this…
The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope
The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419
We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
BICEP/Keck XIX: Extremely Thin Composite Polymer Vacuum Windows for BICEP and Other High Throughput Millimeter Wave Telescopes
Keck Collaboration, P. A. R. Ade, Z. Ahmed +90
Millimeter-wave refracting telescopes targeting the degree-scale structure of the cosmic microwave background (CMB) have recently grown to diffraction-limited apertures of over 0.5…
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…
Development of the 220/270 GHz Receiver of BICEP Array
Keck Collaboration, Y. Nakato, P. A. R. Ade +82
Measurements of B-mode polarization in the CMB sourced from primordial gravitational waves would provide information on the energy scale of inflation and its potential form. To ach…
Constraining Inflation with the BICEP/Keck CMB Polarization Experiments
Keck Collaboration, P. A. R. Ade, Z. Ahmed +84
The BICEP/ (BK) series of cosmic microwave background (CMB) polarization experiments has, over the past decade and a half, produced a series of field-leading constra…
