Upcoming large-scale structure surveys require accurate theoretical predictions for angular power spectra on the largest angular scales, where the commonly used Limber approximatio…
Fisher Forecasting for the DESC with
Paul Rogozenski, Sankarshana Srinivasan, Javier Sánchez +15
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) has begun its ten-year survey of the entire visible southern hemisphere. To ensure robust cosmological measurem…
The Status of Single Scalar Field Dark Energy
Carlos García-García, Pedro G. Ferreira, William J. Wolf
We present an assessment of the current observational status of single scalar field models of dark energy. Motivated by recent cosmological measurements -- including baryon acousti…

Euclid Collaboration, E. Sarpa, A. Veropalumbo +296
We present the first end-to-end validation of the Euclid baryon acoustic oscillation (BAO) analysis pipeline, encompassing density-field reconstruction, two-point correlation funct…
Propagating data-driven galaxy redshift distribution uncertainties in 32-pt analyses
Jaime Ruiz-Zapatero, Qianjun Hang, Yun-Hao Zhang +7
Uncertainties in the radial distribution of galaxies, , are one of the major contributions to the error budget of early Stage-IV galaxy survey analy…

We present a novel method for the tomographic reconstruction of the bias-weighted mean electron pressure and star formation rate density $\langle bρ_{\mathrm…
Low-redshift constraints on structure growth from CMB lensing tomography
Andrea Rubiola, Matteo Zennaro, Carlos García-García +2
We present constraints on the amplitude of matter fluctuations from the clustering of galaxies and their cross-correlation with the gravitational lensing convergence of the cosmic…
Cosmological constraints on Galileon dark energy with broken shift symmetry
William J. Wolf, Pedro G. Ferreira, Carlos García-García
Current cosmological data seem to show that dark energy is evolving in time and that it possibly crossed the phantom divide in the past. So far the only theories that lead to such…
Assessing cosmological evidence for non-minimal coupling
William J. Wolf, Carlos García-García, Theodore Anton +1
The recent observational evidence of deviations from the -Cold Dark Matter (CDM) model points towards the presence of evolving dark energy. The simplest possibility consists…
Robust cosmic shear with small-scale nulling
Giulia Piccirilli, Matteo Zennaro, Carlos García-García +1
Standard cosmological weak lensing analyses using cosmic shear are inevitably sensitive to small-scale, non-linear clustering from low-redshift structures. The need to adequately m…
Robustness of dark energy phenomenology across different parameterizations
William J. Wolf, Carlos García-García, Pedro G. Ferreira
The recent evidence for dynamical dark energy from DESI, in combination with other cosmological data, has generated significant interest in understanding the nature of dark energy…
A 1% accurate method to include baryonic effects in galaxy-galaxy lensing models
Matteo Zennaro, Giovanni Aricò, Carlos García-García +6
Galaxy clustering and galaxy-galaxy lensing are two of the main observational probes in Stage-IV large-scale structure surveys. Unfortunately, the complicated relationship between…
: insights on gas thermodynamics from the combination of X-ray and thermal Sunyaev-Zel'dovich data cross-correlated with cosmic shear
Adrien La Posta, David Alonso, Nora Elisa Chisari +2
We measure the cross-correlation between cosmic shear from the third-year release of the Dark Energy Survey, thermal Sunyaev-Zel'dovich (tSZ) maps from Planck, and X-ray maps from…
: Normalising Flows for Joint Cosmological Analysis
Arrykrishna Mootoovaloo, Carlos García-García, David Alonso +1
Given the growth in the variety and precision of astronomical datasets of interest for cosmology, the best cosmological constraints are invariably obtained by combining data from d…
Matching current observational constraints with nonminimally coupled dark energy
William J. Wolf, Pedro G. Ferreira, Carlos García-García
We show that a Universe with a nonminimally coupled scalar field can fit current measurements of the expansion rate of the Universe better than the standard -Cold Dark Matter ($…
Scant evidence for thawing quintessence
William J. Wolf, Carlos García-García, Deaglan J. Bartlett +1
New constraints on the expansion rate of the Universe seem to favor evolving dark energy in the form of thawing quintessence models, i.e., models for which a canonical, minimally c…
Assessment of Gradient-Based Samplers in Standard Cosmological Likelihoods
Arrykrishna Mootoovaloo, Jaime Ruiz-Zapatero, Carlos García-García +1
We assess the usefulness of gradient-based samplers, such as the No-U-Turn Sampler (NUTS), by comparison with traditional Metropolis-Hastings algorithms, in tomographic $3 \times 2…
