JZ-Tree: GPU friendly neighbour search and friends-of-friends with dual tree walks in JAX plus CUDA
Jens Stücker, Oliver Hahn, Lukas Winkler +2
Algorithms based on spatial tree traversal are widely regarded as among the most efficient and flexible approaches for many problems in CPU-based high-performance computing (HPC).…
Unclustered tracers remain unclustered: the lack of primordial non-Gaussianity response of bias-zero tracers
Celia Merino, Santiago Avila, A. G. Adame +3
Constraining primordial non-Gaussianities (PNG) is one of the main goals of new-generation large-scale galaxy surveys. It had been proposed that unclustered tracers (with bias $b_1…
Accurate -body simulations with local Primordial non-Gaussianities: initial conditions and aliasing
Adrian G. Adame, Santiago Avila, Violeta Gonzalez-Perez +3
New generation galaxy surveys targeting constraints on local primordial non-Gaussianity (PNG) demand -body simulations that accurately reproduce its effects. In this work, we ex…
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…
DESI 2024 II: Sample Definitions, Characteristics, and Two-point Clustering Statistics
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present the samples of galaxies and quasars used for DESI 2024 cosmological analyses, drawn from the DESI Data Release 1 (DR1). We describe the construction of large-scale struc…
Euclid preparation LXIII. Simulations and nonlinearities beyond CDM. 2. Results from non-standard simulations
Euclid Collaboration, G. Rácz, M. -A. Breton +275
The Euclid mission will measure cosmological parameters with unprecedented precision. To distinguish between cosmological models, it is essential to generate realistic mock observa…
DESI 2024 III: Baryon Acoustic Oscillations from Galaxies and Quasars
DESI Collaboration, A. G. Adame, J. Aguilar +193
We present the DESI 2024 galaxy and quasar baryon acoustic oscillations (BAO) measurements using over 5.7 million unique galaxy and quasar redshifts in the range 0.1<z<2.1. Divided…
DESI 2024 VI: Cosmological Constraints from the Measurements of Baryon Acoustic Oscillations
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present cosmological results from the measurement of baryon acoustic oscillations (BAO) in galaxy, quasar and Lyman- forest tracers from the first year of observations from t…
DESI 2024 IV: Baryon Acoustic Oscillations from the Lyman Alpha Forest
DESI Collaboration, A. G. Adame, J. Aguilar +196
We present the measurement of Baryon Acoustic Oscillations (BAO) from the Lyman- (Ly) forest of high-redshift quasars with the first-year dataset of the Dark Energy Spectrosc…
Constraining primordial non-Gaussianity from the large scale structure two-point and three-point correlation functions
Z. Brown, R. Demina, A. G. Adame +47
Surveys of cosmological large-scale structure (LSS) are sensitive to the presence of local primordial non-Gaussianity (PNG), and may be used to constrain models of inflation. Local…
PNG-UNITsims: Halo clustering response to primordial non-Gaussianities as a function of mass
Adrian G. Adame, Santiago Avila, Violeta Gonzalez-Perez +7
We present the largest full N-body simulation to date with local primordial non-Gaussianities (L-PNG), the \textsc{PNG-UNITsim}. It tracks the evolution of particles withi…
Primordial non-Gaussianity with Angular correlation function: Integral constraint and validation for DES
Walter Riquelme, Santiago Avila, Juan Garcia-Bellido +17
Local primordial non-Gaussianity (PNG) is a promising observable of the underlying physics of inflation, characterised by . We present the methodology to meas…
Validating galaxy clustering models with Fixed & Paired and Matched-ICs simulations: application to Primordial Non-Gaussianities
Santiago Avila, Adrian G. Adame
The Fix and Pair techniques were designed to generate simulations with reduced variance in the 2-point statistics by modifying the Initial Conditions (ICs). In this paper we show t…
