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…

J-PAS: forecast on the primordial power spectrum reconstruction
Guillermo MartÃnez-Somonte, Airam Marcos-Caballero, Enrique MartÃnez-González +27
We investigate the capability of the J-PAS survey to constrain the primordial power spectrum using a non-parametric Bayesian method. Specifically, we analyze simulated power spectr…

Bayesian inference methodology for Primordial Power Spectrum reconstructions from Large Scale Structure
G. MartÃnez-Somonte, A. Marcos-Caballero, E. MartÃnez-González +1
We use Bayesian inference and nested sampling to develop a non-parametric method to reconstruct the primordial power spectrum from Large Scale Structure (LSS)…
