Validation of the DESI DR2 Ly forest full-shape analysis
M. Herbold, A. Cuceu, P. Martini +100
We present the validation of the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (DR2) Lyman- (Ly) forest full-shape analysis. This analysis combines three-dimensi…
DESI DR2 Results IV: Alcock-Paczyński Measurements from the Lyman Alpha Forest and Cosmological Constraints
DESI Collaboration, A. G. Adame, J. Aguilar +152
We present Alcock-Paczyński (AP) measurements from the full shape of Lyman- (Ly) forest correlation functions measured from the second data release (DR2) of the Dark Energy S…
CoLoRe-2LPT: Lyman- mock catalogues for the validation of DESI cosmological analyses
M. F. Ruiz-Herrera Bernal, S. Avila, A. Font-Ribera +90
The Lyman- (Ly) forest has become a crucial probe for studying the large-scale structure of the universe at high redshift (), providing powerful constraints on Baryon…
CHEFT: A Hybrid Effective Field Theory halo model
Marcos Pellejero Ibáñez, David Alonso, John A. Peacock +2
We present a hybrid halo model, which improves the description of the 2-halo term by incorporating non-linear information from simulations. A linear computation of the halo-halo po…
Validation of the Hybrid Bias Expansion model for the galaxy bispectrum
Marcos Pellejero Ibáñez, Raul E. Angulo, Laila Linke +8
The Hybrid Bias Expansion model (also known as Hybrid Effective Field Theory, HEFT) provides a promising way to extend the range of validity of perturbative large-scale structure m…
FolpsD: combining EFT and phenomenological approaches for joint power spectrum and bispectrum analyses
P. Bansal, A. Aviles, H. E. Noriega +56
We present a theoretical model for the power spectrum and bispectrum of galaxy clustering that exploits the complementarity between small-scale power spectrum information and large…
Euclid preparation. Galaxy 2-point correlation function modelling in redshift space
Euclid Collaboration, M. Kärcher, M. -A. Breton +309
The Euclid satellite will measure spectroscopic redshifts for tens of millions of emission-line galaxies. In the context of Stage-IV surveys, the 3-dimensional clustering of galaxi…
Euclid preparation. Galaxy power spectrum modelling in redshift space
Euclid Collaboration, B. Camacho Quevedo, M. Crocce +292
Accurate modelling of redshift-space distortions (RSD) is essential for maximizing the cosmological information extracted from large galaxy redshift surveys. In preparation for the…
DESI DR2 Results II: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints
DESI Collaboration, M. Abdul-Karim, J. Aguilar +184
We present baryon acoustic oscillation (BAO) measurements from more than 14 million galaxies and quasars drawn from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (…
Cosmological constraints from the full-shape galaxy power spectrum in SDSS-III BOSS using the BACCO hybrid Lagrangian bias emulator
Marcos Pellejero Ibáñez, Raul E. Angulo, John A. Peacock
We present a novel analysis of the redshift-space power spectrum of galaxies in the SDSS-III BOSS survey. Our methodology improves upon previous analyses by using a theoretical mod…
A Parameter-Masked Mock Data Challenge for Beyond-Two-Point Galaxy Clustering Statistics

Euclid Collaboration, A. Pezzotta, C. Moretti +246
We investigate the accuracy of the perturbative galaxy bias expansion in view of the forthcoming analysis of the Euclid spectroscopic galaxy samples. We compare the performance of…
Characterizing Structure Formation through Instance Segmentation
Daniel López-Cano, Jens Stücker, Marcos Pellejero Ibañez +2
Dark matter haloes form from small perturbations to the almost homogeneous density field of the early universe. Although it is known how large these initial perturbations must be t…
Hybrid-bias and displacement emulators for field-level modelling of galaxy clustering in real and redshift space
