About this document
CMB and Lyman-α Forest Analysis by krishna is a document available to read on EtoBox.
This document presents new constraints on the primordial power spectrum by analyzing data from Planck, ACT DR6, SPT-3G, and eBOSS Lyman-α forest, revealing a significant indication of nonzero running of the spectral index. The inclusion of eBOSS data tightens constraints on the running parameters, suggesting a more complex scale dependence that challenges simple inflationary models. The authors also release the PIPE code for testing various inflationary potentials against current datasets.
