Cosmological constraints from a joint DESI DR1 Full-Shape and DR2 BAO
D. Forero-Sánchez, H. Gil-Marín, L. Verde +61
We present a cosmological analysis combining full-shape (FS) clustering measurements from the Dark Energy Spectroscopic Instrument (DESI) DR1 with baryon acoustic oscillation (BAO)…
The Impact of Spectroscopic Redshift Errors on Cosmological Measurements
Shengyu He, Jiaxi Yu, Antoine Rocher +5
Spectroscopic redshift errors, including redshift uncertainty and catastrophic failures, can bias cosmological measurements from galaxy redshift surveys at sub-percent level. In th…
Model-Independent Measurement of the Matter-Radiation Equality Scale in DESI 2024
B. Bahr-Kalus, D. Parkinson, K. Lodha +52
The peak of the matter power spectrum, known as the turnover (TO) scale, is determined by the horizon size at the time of matter-radiation equality. This scale can serve as a stand…
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…
ELG Spectroscopic Systematics Analysis of the DESI Data Release 1
Jiaxi Yu, Ashley J. Ross, Antoine Rocher +58
Dark Energy Spectroscopic Instrument (DESI) uses more than 2.4 million Emission Line Galaxies (ELGs) for 3D large-scale structure (LSS) analyses in its Data Release 1 (DR1). Such l…
CosmoMIA: Cosmic Web-based redshift space halo distribution
Daniel Forero-Sánchez, Francisco-Shu Kitaura, Francesco Sinigaglia +2
Modern galaxy surveys demand extensive survey volumes and resolutions surpassing current dark matter-only simulations' capabilities. To address this, many methods employ effective…
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…
DESI Mock Challenge: Constructing DESI galaxy catalogues based on FastPM simulations
Andrei Variu, Shadab Alam, Cheng Zhao +30
Together with larger spectroscopic surveys such as the Dark Energy Spectroscopic Instrument (DESI), the precision of large scale structure studies and thus the constraints on the c…
The Early Data Release of the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +266
The Dark Energy Spectroscopic Instrument (DESI) completed its five-month Survey Validation in May 2021. Spectra of stellar and extragalactic targets from Survey Validation constitu…
Validation of the Scientific Program for the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +261
The Dark Energy Spectroscopic Instrument (DESI) was designed to conduct a survey covering 14,000 deg over five years to constrain the cosmic expansion history through precise m…
Cosmic void exclusion models and their impact on the distance scale measurements from large scale structure
Andrei Variu, Cheng Zhao, Daniel Forero-Sánchez +5
Baryonic Acoustic Oscillations (BAOs) studies based on the clustering of voids and matter tracers provide important constraints on cosmological parameters related to the expansion…
Void BAO measurements on quasars from eBOSS
A. Tamone, C. Zhao, D. Forero-Sánchez +5
We present the clustering of voids based on the quasar (QSO) sample of the extended Baryon Oscillation Spectroscopic Survey Data Release 16 in configuration space. We define voids…
A Machine Learning Approach to Correct for Mass Resolution Effects in Simulated Halo Clustering Statistics
Daniel Forero-Sánchez, Chia-Hsun Chuang, Sergio Rodríguez-Torres +3
The increase in the observed volume in cosmological surveys imposes various challenges on simulation preparations. Firstly, the volume of the simulations required increases proport…
