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…
The Simons Observatory: Constraining inflationary gravitational waves with multi-tracer B-mode delensing
Toshiya Namikawa, Anton Baleato Lizancos, Naomi Robertson +32
We introduce and validate a delensing framework for the Simons Observatory (SO), which will be used to improve constraints on inflationary gravitational waves (IGWs) by reducing th…
BICEP / Keck XIII: Improved Constraints on Primordial Gravitational Waves using Planck, WMAP, and BICEP/Keck Observations through the 2018 Observing Season
Keck Collaboration, P. A. R. Ade, Z. Ahmed +89
We present results from an analysis of all data taken by the BICEP2, Keck Array and BICEP3 CMB polarization experiments up to and including the 2018 observing season. We add additi…
BICEP / Keck XV: The BICEP3 CMB Polarimeter and the First Three Year Data Set
Keck Collaboration, P. A. R. Ade, Z. Ahmed +89
We report on the design and performance of the BICEP3 instrument and its first three-year data set collected from 2016 to 2018. BICEP3 is a 52cm aperture, refracting telescope desi…
Cosmic birefringence tomography and calibration-independence with reionization signals in the CMB
Blake D. Sherwin, Toshiya Namikawa
The search for cosmic polarization rotation or birefringence in the CMB is well-motivated because it can provide powerful constraints on parity-violating new physics, such as axion…
BICEP / Keck XIV: Improved constraints on axion-like polarization oscillations in the cosmic microwave background
Keck Collaboration, P. A. R. Ade, Z. Ahmed +89
We present an improved search for axion-like polarization oscillations in the cosmic microwave background (CMB) with observations from the Keck Array. An all-sky, temporally sinuso…
CMB Mode Coupling with Isotropic Polarization Rotation
Toshiya Namikawa
We provide a new analysis technique to measure the effect of the isotropic polarization rotation, induced by e.g. the isotropic cosmic birefringence from axion-like particles and a…
The Atacama Cosmology Telescope: Summary of DR4 and DR5 Data Products and Data Access
Maya Mallaby-Kay, Zachary Atkins, Simone Aiola +57
Two recent large data releases for the Atacama Cosmology Telescope (ACT), called DR4 and DR5, are available for public access. These data include temperature and polarization maps…
Position-Dependent Correlation Function of Weak Lensing Convergence
D. Munshi, G. Jung, T. D. Kitching +4
We provide a systematic study of the position-dependent correlation function in weak lensing convergence maps and its relation to the squeezed limit of the three-point correlation…
Unified approach to secondary effects on the CMB B-mode polarization
Toshiya Namikawa, Atsushi Naruko, Ryo Saito +2
We develop a systematic and unified approach to estimate all possible secondary (i.e. non-primordial) nonlinear effects to the cosmic microwave background (CMB) polarization, named…
Analysis of Temperature-to-Polarization Leakage in BICEP3 and Keck CMB Data from 2016 to 2018
Keck Collaboration, T. St. Germaine, P. A. R. Ade +85
The BICEP/Keck Array experiment is a series of small-aperture refracting telescopes observing degree-scale Cosmic Microwave Background polarization from the South Pole in search of…
The integrated angular bispectrum of weak lensing
Gabriel Jung, Toshiya Namikawa, Michele Liguori +2
We investigate three-point statistics in weak lensing convergence, through the integrated bispectrum. This statistic involves measuring power spectra in patches, and is thus easy t…
Delensing the CMB with the cosmic infrared background: the impact of foregrounds
Antón Baleato Lizancos, Anthony Challinor, Blake D. Sherwin +1
The most promising avenue for detecting primordial gravitational waves from cosmic inflation is through measurements of degree-scale CMB -mode polarisation. This approach must f…
Constraining reionization with the first measurement of the cross-correlation between the CMB optical-depth fluctuations and the Compton y-map
Toshiya Namikawa, Anirban Roy, Blake D. Sherwin +2
We propose a new reionization probe that uses cosmic microwave background (CMB) observations; the cross-correlation between fluctuations in the CMB optical depth which probes the i…
