Early against Late: A contrast on dark energy in the light of DESI DR2
Miguel A. Zapata, Karim Carrion, Gabriela Garcia-Arroyo
Recent findings from Dark Energy Spectroscopic Instrument (DESI) Baryon Acoustic Oscillation (BAO) measurements, combined with Type Ia supernovae and Cosmic Microwave Background (C…
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…
Lyman- forest holography: 3D predictions from 1D measurements
J. Chaves-Montero, A. Font-Ribera, J. Aguilar +68
Cosmological analyses of Lyman- forest clustering rely on either one-dimensional correlations along individual sightlines or three-dimensional correlations between different sig…
Bayesian analysis of -Starobinsky model with Planck, ACT and DESI data
Karim Carrion, Francisco X. Linares Cedeño, Gabriel Germán +1
We present a joint Bayesian analysis to impose constraints on the generalized -Starobinsky inflationary model using the high-precision cosmological datasets: Planck, CMB lensing…
Accelerating cosmological inference of interacting dark energy with neural emulators
Karim Carrion
The present thesis aims to tackle two critical aspects of present and future cosmological analysis of Large-Scale Structure (LSS): accurate modelling of the nonlinear matter power…
Testing interacting dark energy with Stage IV cosmic shear surveys through differentiable neural emulators
Karim Carrion, Alessio Spurio Mancini, Davide Piras +1
We employ a novel framework for accelerated cosmological inference, based on neural emulators and gradient-based sampling methods, to forecast constraints on dark energy models fro…
Dark Scattering: accelerated constraints from KiDS-1000 with and
Karim Carrion, Pedro Carrilho, Alessio Spurio Mancini +2
We present constraints on the Dark Scattering model through cosmic shear measurements from the Kilo Degree Survey (KiDS-1000), using an accelerated pipeline with novel emulators pr…
On the road to percent accuracy VI: the nonlinear power spectrum for interacting dark energy with baryonic feedback and massive neutrinos
Pedro Carrilho, Karim Carrion, Benjamin Bose +4
Understanding nonlinear structure formation is crucial for fully exploring the data generated by stage IV surveys, requiring accurate modelling of the power spectrum. This is chall…
Complex Scalar Field Reheating and Primordial Black Hole production
Karim Carrion, Juan Carlos Hidalgo, Ariadna Montiel +1
We study perturbations of a complex scalar field during reheating with no self-interaction in the regime , when the scalar field has a fast oscillatory behaviour (close to…
