Bispectrum BAO and the baryon-dark matter relative velocity
Adriana Nadal-Matosas, Héctor Gil-MarÃn, Licia Verde
We evaluate the Baryon Acoustic Oscillation (BAO) signal in the bispectrum as a tool to detect and characterize the relative velocity effect. We extend the existing framework by pr…
Exploring the Dark Sector: Interacting Radiation in Light of Modern Cosmological Probes
Matteo Mescia, Héctor Gil-MarÃn
[abridged] We constrain a phenomenological dark radiation (DR) framework consisting of free-streaming and fluid-like components, providing a model-independent extension of the stan…
Primordial power spectrum reconstructions from BOSS + eBOSS
Guillermo MartÃnez-Somonte, Héctor Gil-MarÃn, Airam Marcos-Caballero +1
We reconstruct the primordial power spectrum from the BOSS DR 12 LRG and eBOSS DR 16 QSO catalogs with a non-parametric Bayesian method. The $P_{\mathcal{R}}(k…
Modified Gravity Constraints from the Full Shape Modeling of Clustering Measurements from DESI 2024
M. Ishak, J. Pan, R. Calderon +68
We present cosmological constraints on deviations from general relativity (GR) from the first-year of clustering observations from Dark Energy Spectroscopic Instrument (DESI) in co…
Constraints on Neutrino Physics from DESI DR2 BAO and DR1 Full Shape
W. Elbers, A. Aviles, H. E. Noriega +116
The Dark Energy Spectroscopic Instrument (DESI) Collaboration has obtained robust measurements of baryon acoustic oscillations (BAO) in the redshift range, , based o…
Validating the Galaxy and Quasar Catalog-Level Blinding Scheme for the DESI 2024 analysis
U. Andrade, J. Mena-Fernández, H. Awan +60
In the era of precision cosmology, ensuring the integrity of data analysis through blinding techniques is paramount -- a challenge particularly relevant for the Dark Energy Spectro…
