Cosmological gravity probes: connecting recent theoretical developments to forthcoming observations
Shun Arai, Katsuki Aoki, Yuji Chinone +20
Since the discovery of the accelerated expansion of the present Universe, significant theoretical developments have been made in the area of modified gravity. In the meantime, cosm…
The reconstructed CMB lensing bispectrum
Alba Kalaja, Giorgio Orlando, Aleksandr Bowkis +3
Weak gravitational lensing by the intervening large-scale structure (LSS) of the Universe is the leading non-linear effect on the anisotropies of the cosmic microwave background (C…
BICEP / Keck XVII: Line of Sight Distortion Analysis: Estimates of Gravitational Lensing, Anisotropic Cosmic Birefringence, Patchy Reionization, and Systematic Errors
Keck Collaboration, P. A. R. Ade, Z. Ahmed +91
We present estimates of line-of-sight distortion fields derived from the 95 GHz and 150 GHz data taken by BICEP2, BICEP3, and Keck Array up to the 2018 observing season, leading to…
BICEP / Keck XVI: Characterizing Dust Polarization through Correlations with Neutral Hydrogen
Keck Collaboration, P. A. R. Ade, Z. Ahmed +92
We characterize Galactic dust filaments by correlating BICEP/Keck and Planck data with polarization templates based on neutral hydrogen (H I) observations. Dust polarization is imp…
Impact of Anisotropic Birefringence on Measuring Cosmic Microwave Background Lensing
Hongbo Cai, Yilun Guan, Toshiya Namikawa +1
The power spectrum of cosmic microwave background lensing is a powerful tool for constraining fundamental physics such as the sum of neutrino masses and the dark energy equation of…
Isotropic cosmic birefringence from early dark energy
Kai Murai, Fumihiro Naokawa, Toshiya Namikawa +1
A tantalizing hint of isotropic cosmic birefringence has been found in the cross-power spectrum of the cosmic microwave background (CMB) polarization data with a statistical…
Improved Polarization Calibration of the BICEP3 CMB Polarimeter at the South Pole
J. Cornelison, C. Vergès, P. A. R. Ade +83
The BICEP3 Polarimeter is a small aperture, refracting telescope, dedicated to the observation of the Cosmic Microwave Background (CMB) at 95GHz. It is designed to target degree an…
Thermal Testing for Cryogenic CMB Instrument Optical Design
D. C. Goldfinger, P. A. R. Ade, Z. Ahmed +83
Observations of the Cosmic Microwave Background rely on cryogenic instrumentation with cold detectors, readout, and optics providing the low noise performance and instrumental stab…
Probing early structure and model-independent neutrino mass with high-redshift CMB lensing mass maps
Frank J. Qu, Blake D. Sherwin, Omar Darwish +2
CMB lensing maps probe the mass distribution in projection out to high redshifts, but significant sensitivity to low-redshift structure remains. In this paper we discuss a method t…
2022 Upgrade and Improved Low Frequency Camera Sensitivity for CMB Observation at the South Pole
A. Soliman, P. A. R. Ade, Z. Ahmed +83
Constraining the Galactic foregrounds with multi-frequency Cosmic Microwave Background (CMB) observations is an essential step towards ultimately reaching the sensitivity to measur…
Is cosmic birefringence due to dark energy or dark matter? A tomographic approach
Hiromasa Nakatsuka, Toshiya Namikawa, Eiichiro Komatsu
A pseudoscalar "axionlike" field, , may explain the hint of cosmic birefringence observed in the power spectrum of the cosmic microwave background (CMB) polarization d…

Kevork Abazajian, Arwa Abdulghafour, Graeme E. Addison +353
This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin a…
Snowmass2021 CMB-HD White Paper
HD Collaboration, Simone Aiola, Yashar Akrami +61
CMB-HD is a proposed millimeter-wave survey over half the sky that would be ultra-deep (0.5 uK-arcmin) and have unprecedented resolution (15 arcseconds at 150 GHz). Such a survey w…

Finding Evidence for Inflation and the Origin of Galactic Magnetic Fields with CMB Surveys
Sayan Mandal, Neelima Sehgal, Toshiya Namikawa
The origin of the G magnetic fields observed in galaxies is unknown. One promising scenario is that magnetic fields generated during inflation, larger than 0.1 nG on Mpc scales,…
