Characteristic Functions for Cosmological Cross-Correlations
Patrick C. Breysse, Dongwoo T. Chung, Håvard T. Ihle
We introduce a novel unbiased, cross-correlation estimator for the one-point statistics of cosmological random fields. One-point statistics are a useful tool for analysis of highly…
The deconvolved distribution estimator: enhancing reionisation-era CO line-intensity mapping analyses with a cross-correlation analogue for one-point statistics
Dongwoo T. Chung, Ishika Bangari, Patrick C. Breysse +7
We present the deconvolved distribution estimator (DDE), an extension of the voxel intensity distribution (VID), in the context of future observations proposed as part of the CO Ma…
BeyondPlanck VIII. Efficient Sidelobe Convolution and Correction through Spin Harmonics
M. Galloway, M. Reinecke, K. J. Andersen +35
We introduce a new formulation of the Conviqt convolution algorithm in terms of spin harmonics, and apply this to the problem of sidelobe correction for BeyondPlanck, the first end…
COMAP Early Science: I. Overview
Kieran A. Cleary, Jowita Borowska, Patrick C. Breysse +40
The CO Mapping Array Project (COMAP) aims to use line intensity mapping of carbon monoxide (CO) to trace the distribution and global properties of galaxies over cosmic time, back t…
COMAP Early Science: VII. Prospects for CO Intensity Mapping at Reionization
Patrick C. Breysse, Dongwoo T. Chung, Kieran A. Cleary +29
We introduce COMAP-EoR, the next generation of the Carbon Monoxide Mapping Array Project aimed at extending CO intensity mapping to the Epoch of Reionization. COMAP-EoR supplements…
COMAP Early Science: V. Constraints and Forecasts at
Dongwoo T. Chung, Patrick C. Breysse, Kieran A. Cleary +34
We present the current state of models for the carbon monoxide (CO) line-intensity signal targeted by the CO Mapping Array Project (COMAP) Pathfinder in the context of its…
COMAP Early Science: IV. Power Spectrum Methodology and Results
Håvard T. Ihle, Jowita Borowska, Kieran A. Cleary +30
We present the power spectrum methodology used for the first-season COMAP analysis, and assess the quality of the current data set. The main results are derived through the Feed-fe…
A model of spectral line broadening in signal forecasts for line-intensity mapping experiments
Dongwoo T. Chung, Patrick C. Breysse, Håvard Tveit Ihle +15
Line-intensity mapping observations will find fluctuations of integrated line emission are attenuated by varying degrees at small scales due to the width of the line emission profi…
BeyondPlanck II. CMB map-making through Gibbs sampling
E. Keihänen, A. -S. Suur-Uski, K. J. Andersen +37
We present a Gibbs sampling solution to the map-making problem for CMB measurements, building on existing destriping methodology. Gibbs sampling breaks the computationally heavy de…
BeyondPlanck VII. Bayesian estimation of gain and absolute calibration for CMB experiments
E. Gjerløw, H. T. Ihle, S. Galeotta +35
We present a Bayesian calibration algorithm for CMB observations as implemented within the global end-to-end BeyondPlanck (BP) framework, and apply this to the Planck Low Frequency…
BeyondPlanck VI. Noise characterization and modelling
H. T. Ihle, M. Bersanelli, C. Franceschet +38
We present a Bayesian method for estimating instrumental noise parameters and propagating noise uncertainties within the global BeyondPlanck Gibbs sampling framework, and apply thi…
BeyondPlanck I. Global Bayesian analysis of the Planck Low Frequency Instrument data
BeyondPlanck Collaboration, K. J. Andersen, R. Aurlien +42
We describe the BeyondPlanck project in terms of motivation, methodology and main products, and provide a guide to a set of companion papers that describe each result in fuller det…
Testing for foreground residuals in the Planck foreground cleaned maps: A new method for designing confidence masks
M. Axelsson, H. T. Ihle, S. Scodeller +1
We test for foreground residuals in the foreground cleaned Planck Cosmic Microwave Background (CMB) maps outside and inside U73 mask commonly used for cosmological analysis. The ai…
