Hunting Thermal Relics in the DESI DR1 Ly Forest
Emanuelly Silva, Artur Ladeira, Rafael C. Nunes +1
We investigate constraints on additional relativistic species and thermal sterile neutrinos using the DESI DR1 one-dimensional Lyman- forest power spectrum, combined with Planck…
Testing MOND-like modifications to gravity using growth-rate measurements and one-loop corrections to the matter power spectrum
Gabriel Hartmann, Emanuelly Silva, Rafael C. Nunes
We develop a perturbative framework for structure formation in a broad class of MOND-like theories characterized by a generalized nonlinear Poisson equation. We derive the modified…
Probing dynamical embeddings in a five-dimensional spacetime in light of DESI BAO
Abraão J. S. Capistrano, Emanuelly Silva, Rafael C. Nunes +1
We here investigate the observational viability of Nash gravity as an alternative to the standard CDM cosmology. Based on Nash's embedding theorem, the model introduces orthogon…
One-loop power spectrum corrections in interacting dark energy cosmologies
Emanuelly Silva, Gabriel Hartmann, Rafael C. Nunes
Interacting Dark Energy (IDE) models offer a promising avenue to explore possible exchanges of energy and momentum between dark matter and dark energy, providing a dynamical extens…
Testing signatures of phantom crossing through full-shape galaxy clustering analysis
Emanuelly Silva, Rafael C. Nunes
Recent observations of baryon acoustic oscillations (BAO) from the Dark Energy Spectroscopic Instrument (DESI) survey, when combined with measurements of the cosmic microwave backg…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
New constraints on interacting dark energy from DESI DR2 BAO observations
Emanuelly Silva, Miguel A. Sabogal, Mateus Scherer +3
In its second data release (DR2), the Dark Energy Spectroscopic Instrument (DESI) publicly released measurements of Baryon Acoustic Oscillations (BAO) from over 13.1 million galaxi…
Sign Switching in Dark Sector Coupling Interactions as a Candidate for Resolving Cosmological Tensions
Miguel A. Sabogal, Emanuelly Silva, Rafael C. Nunes +2
The CDM model has successfully explained a wide range of cosmological observations, but is increasingly challenged by the emergence of cosmological tensions, particularly the Hu…
Quantifying the tension and evidence for interacting dark energy from redshift-space distortion measurements
Miguel A. Sabogal, Emanuelly Silva, Rafael C. Nunes +3
In recent years, Cosmic Microwave Background (CMB) observations, Weak Lensing surveys, and measurements from Redshift-Space Distortions (RSD) have revealed a significant…
Non-Linear Matter Power Spectrum Modeling in Interacting Dark Energy Cosmologies
Emanuelly Silva, Ubaldo Zúñiga-Bolaño, Rafael C. Nunes +1
Understanding the behavior of the matter power spectrum on non-linear scales beyond the CDM model is crucial for accurately predicting the large-scale structure (LSS) of the Uni…
