Bispectrum BAO and the baryon-dark matter relative velocity
Adriana Nadal-Matosas, Héctor Gil-Marín, 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-Marín
[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 Martínez-Somonte, Héctor Gil-Marín, 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…
