The 3D clustering of Lyman Alpha Emitters measured with DESI
Haruki Ebina, Martin J. White, Rongpu Zhou +44
We present a clustering analysis of Lyman- emitters (LAEs) using spectroscopic observations from the Dark Energy Spectroscopic Instrument (DESI) of candidates selected from the…
An analytic approximation to the covariance between pre- and post-reconstruction galaxy two-point statistics
M. Maus, A. Baleato Lizancos, M. White +2
We present a simple analytic approximation for the covariance between pre-reconstruction galaxy power spectrum measurements and post-reconstruction two-point correlation functions.…
Fewer simulations, sharper covariances: Reducing mock covariance noise with Zeldovich approximation control variates
Boryana Hadzhiyska, Martin White
We present a control-variate method for reducing the variance of power spectrum covariance matrix estimates from simulations of large-scale structure. The key idea is to pair each…
Steeling Weak Lensing Source Galaxy Samples against Systematics using Wide Field Spectroscopy
Joseph DeRose, Noah Weaverdyck, Martin White +3
We investigate the cosmological constraining power of combined weak galaxy lensing and galaxy clustering probes, i.e. -point analyses, assuming flexible models for redshi…
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…
The Marked Power Spectrum as a Practical Bispectrum Measure for Galaxy Redshift Surveys
Haruki Ebina, Martin White, Edmond Chaussidon
Modern datasets have the precision necessary to uncover new information by including higher-order, non-Gaussian information into cosmological inference. The marked power spectrum o…
