Baryon Acoustic Oscillation Theory and Modelling Systematics for the DESI 2024 results
Shi-Fan Chen, Cullan Howlett, Martin White +58
This paper provides a comprehensive overview of how fitting of Baryon Acoustic Oscillations (BAO) is carried out within the upcoming Dark Energy Spectroscopic Instrument's (DESI) 2…
Detection of the large-scale tidal field with galaxy multiplet alignment in the DESI Y1 spectroscopic survey
Claire Lamman, Daniel Eisenstein, Jaime E. Forero-Romero +36
We explore correlations between the orientations of small galaxy groups, or "multiplets", and the large-scale gravitational tidal field. Using data from the Dark Energy Spectroscop…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Cosmological Implications from two Decades of Spectroscopic Surveys at the Apache Point observatory
eBOSS Collaboration, Shadab Alam, Marie Aubert +97
We present the cosmological implications from final measurements of clustering using galaxies, quasars, and Ly forests from the completed Sloan Digital Sky Survey (SDSS) lineag…
Local primordial non-Gaussianity from the large-scale clustering of photometric DESI luminous red galaxies
Mehdi Rezaie, Ashley J. Ross, Hee-Jong Seo +46
We use angular clustering of luminous red galaxies from the Dark Energy Spectroscopic Instrument (DESI) imaging surveys to constrain the local primordial non-Gaussianity parameter…
