DESC DC2 Data Release Note
LSST Dark Energy Science Collaboration, Bela Abolfathi, Robert Armstrong +54
In preparation for cosmological analyses of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), the LSST Dark Energy Science Collaboration (LSST DESC) has created…
Instrumental systematics biases in CMB lensing reconstruction: a simulation-based assessment
Mark Mirmelstein, Giulio Fabbian, Antony Lewis +1
Weak gravitational lensing of the cosmic microwave background (CMB) is an important cosmological tool that allows us to learn about the structure, composition and evolution of the…
Internal delensing of Cosmic Microwave Background polarization B-modes with the POLARBEAR experiment
S. Adachi, M. A. O. Aguilar Faúndez, Y. Akiba +51
Using only cosmic microwave background polarization data from the POLARBEAR experiment, we measure -mode polarization delensing on subdegree scales at more than significanc…
The Simons Observatory: Science goals and forecasts
The Simons Observatory Collaboration, Peter Ade, James Aguirre +247
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scient…
A Measurement of the Cosmic Microwave Background -Mode Polarization Power Spectrum at Sub-Degree Scales from 2 years of POLARBEAR Data
The POLARBEAR Collaboration, P. A. R. Ade, M. Aguilar +79
We report an improved measurement of the cosmic microwave background (CMB) -mode polarization power spectrum with the POLARBEAR experiment at 150 GHz. By adding new data collect…
Full covariance of CMB and lensing reconstruction power spectra
Julien Peloton, Marcel Schmittfull, Antony Lewis +2
CMB and lensing reconstruction power spectra are powerful probes of cosmology. However they are correlated, since the CMB power spectra are lensed and the lensing reconstruction is…
CMB-S4 Science Book, First Edition
Kevork N. Abazajian, Peter Adshead, Zeeshan Ahmed +83
This book lays out the scientific goals to be addressed by the next-generation ground-based cosmic microwave background experiment, CMB-S4, envisioned to consist of dedicated teles…
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…
Detecting the tensor-to-scalar ratio with the pure pseudospectrum reconstruction of -mode
A. Ferté, J. Peloton, J. Grain +1
In this work we employ the pure-pseudo formalism devised to minimise the effects of the leakage on the variance of power spectrum estimates and discuss the limits on the tensor-to-…
A Measurement of the Cosmic Microwave Background B-Mode Polarization Power Spectrum at Sub-Degree Scales with POLARBEAR
The POLARBEAR Collaboration, P. A. R. Ade, Y. Akiba +71
We report a measurement of the B-mode polarization power spectrum in the cosmic microwave background (CMB) using the POLARBEAR experiment in Chile. The faint B-mode polarization si…
Measurement of the Cosmic Microwave Background Polarization Lensing Power Spectrum with the POLARBEAR experiment
POLARBEAR Collaboration, P. A. R. Ade, Y. Akiba +70
Gravitational lensing due to the large-scale distribution of matter in the cosmos distorts the primordial Cosmic Microwave Background (CMB) and thereby induces new, small-scale …
Evidence for Gravitational Lensing of the Cosmic Microwave Background Polarization from Cross-correlation with the Cosmic Infrared Background
POLARBEAR Collaboration, P. A. R. Ade, Y. Akiba +73
We reconstruct the gravitational lensing convergence signal from Cosmic Microwave Background (CMB) polarization data taken by the POLARBEAR experiment and cross-correlate it with C…
