High-resolution CMB bispectrum estimator with flexible modal basis
Wuhyun Sohn, James R. Fergusson, E. P. S. Shellard
We present a new independent pipeline for the CMB bispectrum estimation of primordial non-Gaussianity and release a public code for constraining bispectrum shapes of interest based…
Projected two- and three-point statistics: Forecasts and mitigation of non-linear RSDs
Oliver Leicht, Tobias Baldauf, James Fergusson +1
The combination of two- and three-point clustering statistics of galaxies and the underlying matter distribution has the potential to break degeneracies between cosmological parame…
The Simons Observatory: Astro2020 Decadal Project Whitepaper
The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi +280
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough…
Planck 2018 results. IX. Constraints on primordial non-Gaussianity
Planck Collaboration, Y. Akrami, F. Arroja +157
We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We compare e…
General modal estimation for cross-bispectra
Maresuke Shiraishi, Michele Liguori, James R. Fergusson +1
We describe a fast, optimal estimator for measuring angular bispectra between two correlated weakly non-Gaussian fields ( and ) from observational datasets, based on a separa…
Advancing the matter bispectrum estimation of large-scale structure: a comparison of dark matter codes
Johnathan Hung, James R. Fergusson, E. P. S. Shellard
Cosmological information from forthcoming galaxy surveys, such as LSST and Euclid, will soon exceed that available from the CMB. Higher order correlation functions, like the bispec…
