Improved Constraints on Cosmic Microwave Background Circular Polarization with CLASS
Thomas Essinger-Hileman, Caleigh Ryan, Yunyang Li +25
We present improved constraints on circular polarization in the cosmic microwave background (CMB) from the Cosmology Large Angular Scale Surveyor (CLASS) experiment using data at 9…
Testing CMB Anomalies in E-mode Polarization with Current and Future Data
Rui Shi, Tobias A. Marriage, John W. Appel +15
In this paper, we explore the power of the cosmic microwave background (CMB) polarization (E-mode) data to corroborate four potential anomalies in CMB temperature data: the lack of…
A Simulation-Based Method for Correcting Mode Coupling in CMB Angular Power Spectra
J. S. -Y. Leung, J. Hartley, J. M. Nagy +67
Modern CMB analysis pipelines regularly employ complex time-domain filters, beam models, masking, and other techniques during the production of sky maps and their corresponding ang…
The XFaster Power Spectrum and Likelihood Estimator for the Analysis of Cosmic Microwave Background Maps
A. E. Gambrel, A. S. Rahlin, X. Song +64
We present the XFaster analysis package. XFaster is a fast, iterative angular power spectrum estimator based on a diagonal approximation to the quadratic Fisher matrix estimator. X…
A Constraint on Primordial -Modes from the First Flight of the SPIDER Balloon-Borne Telescope
SPIDER Collaboration, P. A. R. Ade, M. Amiri +68
We present the first linear polarization measurements from the 2015 long-duration balloon flight of SPIDER, an experiment designed to map the polarization of the cosmic microwave b…
Two-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: A Measurement of Circular Polarization at 40 GHz
Ivan L. Padilla, Joseph R. Eimer, Yunyang Li +32
We report circular polarization measurements from the first two years of observation with the 40 GHz polarimeter of the Cosmology Large Angular Scale Surveyor (CLASS). CLASS is con…
A Projected Estimate of the Reionization Optical Depth Using the CLASS Experiment's Sample-Variance Limited E-Mode Measurement
Duncan J. Watts, Bingjie Wang, Aamir Ali +17
We analyze simulated maps of the Cosmology Large Angular Scale Surveyor (CLASS) experiment and recover a nearly cosmic-variance limited estimate of the reionization optical depth $…
SPIDER: CMB polarimetry from the edge of space
R. Gualtieri, J. P. Filippini, P. A. R. Ade +61
SPIDER is a balloon-borne instrument designed to map the polarization of the millimeter-wave sky at large angular scales. SPIDER targets the B-mode signature of primordial gravitat…
