Data Release 1 of the Dark Energy Spectroscopic Instrument
DESI Collaboration, M. Abdul Karim, A. G. Adame +306
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…
Window convolution of the galaxy clustering bispectrum
Mike Shengbo Wang, Florian Beutler, J. Aguilar +25
In galaxy survey analysis, the observed clustering statistics do not directly match theoretical predictions but rather have been processed by a window function that arises from the…
A comparison of shrinkage estimators of the cosmological precision matrix
Marnix J. Looijmans, Mike Shengbo Wang, Florian Beutler
The determination of the covariance matrix and its inverse, the precision matrix, is critical in the statistical analysis of cosmological measurements. The covariance matrix is typ…
Triumvirate: A Python/C++ package for three-point clustering measurements
Mike Shengbo Wang, Florian Beutler, Naonori S. Sugiyama
Triumvirate is a Python/C++ package for measuring the three-point clustering statistics in large-scale structure (LSS) cosmological analyses. Given a catalogue of discrete particle…
Overview of the DESI Milky Way Survey
Andrew P. Cooper, Sergey E. Koposov, Carlos Allende Prieto +62
We describe the Milky Way Survey (MWS) that will be undertaken with the Dark Energy Spectroscopic Instrument (DESI) on the Mayall 4m telescope at the Kitt Peak National Observatory…
Hybrid-basis inference for large-scale galaxy clustering: combining spherical and Cartesian Fourier analyses
Mike Shengbo Wang, Santiago Avila, Davide Bianchi +2
Future precision cosmology from large-scale structure experiments including the Dark Energy Spectroscopic Instrument (DESI) and Euclid will probe wider and deeper cosmic volumes th…
Impact of Relativistic Effects on the Primordial Non-Gaussianity Signature in the Large-Scale Clustering of Quasars
Mike Shengbo Wang, Florian Beutler, David Bacon
Relativistic effects in clustering observations have been shown to introduce scale-dependent corrections to the galaxy over-density field on large scales, which may hamper the dete…
Cosmological Inference from Galaxy-Clustering Power Spectrum: Gaussianization and Covariance Decomposition
Mike Shengbo Wang, Will J. Percival, Santiago Avila +2
Likelihood fitting to two-point clustering statistics made from galaxy surveys usually assumes a multivariate normal distribution for the measurements, with justification based on…
A Unified Analysis of Four Cosmic Shear Surveys
Chihway Chang, Michael Wang, Scott Dodelson +13
In the past few years, several independent collaborations have presented cosmological constraints from tomographic cosmic shear analyses. These analyses differ in many aspects: the…
