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…
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…
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…
Results and Limits of Time Division Multiplexing for the BICEP Array High Frequency Receivers
S. Fatigoni, P. A. R. Ade, Z. Ahmed +84
Time-Division Multiplexing is the readout architecture of choice for many ground and space experiments, as it is a very mature technology with proven outstanding low-frequency nois…
BICEP Array: 150 GHz detector module development
A. Schillaci, P. A. R. Ade, Z. Ahmed +81
The BICEP/Keck Collaboration is currently leading the quest to the highest sensitivity measurements of the polarized CMB anisotropies on degree scale with a series of cryogenic tel…
BICEP2 / Keck Array VII: Matrix based E/B Separation applied to BICEP2 and the Keck Array
Keck Array, BICEP2 Collaborations, : +63
A linear polarization field on the sphere can be uniquely decomposed into an E-mode and a B-mode component. These two components are analytically defined in terms of spin-2 spheric…
Initial Performance of BICEP3: A Degree Angular Scale 95 GHz Band Polarimeter
W. L. K. Wu, P. A. R. Ade, Z. Ahmed +49
BICEP3 is a aperture telescope with cold, on-axis, refractive optics designed to observe at the band from the South Pole. It is the newest member of the BICEP/Kec…
Planck 2015 results. VII. HFI TOI and beam processing
Planck Collaboration, R. Adam, P. A. R. Ade +225
The Planck High Frequency Instrument (HFI) has observed the full sky at six frequencies (100, 143, 217, 353, 545, and 857 GHz) in intensity and at four frequencies in linear polari…
Planck 2015 results. II. Low Frequency Instrument data processing
Planck Collaboration, P. A. R. Ade, N. Aghanim +213
We present an updated description of the Planck Low Frequency Instrument (LFI) data processing pipeline, associated with the 2015 data release. We point out the places where our re…
BICEP2 III: Instrumental Systematics
BICEP2 Collaboration, P. A. R. Ade, R. W. Aikin +42
In a companion paper we have reported a detection of degree scale -mode polarization at 150 GHz by the BICEP2 experiment. Here we provide a detailed study of potential in…
Planck 2013 results. IX. HFI spectral response
Planck Collaboration, P. A. R. Ade, N. Aghanim +217
The Planck High Frequency Instrument (HFI) spectral response was determined through a series of ground based tests conducted with the HFI focal plane in a cryogenic environment pri…
