New Method Analyzes Curved Primordial Tensor Spectra

A new research paper, ‘Analytical approximations for curved primordial tensor spectra,’ submitted to arXiv’s Astrophysics section on November 14, 2025, introduces an analytical approximation method for analyzing primordial tensor power spectra.

This work contributes to the fields of Cosmology and Nongalactic Astrophysics (astro-ph.CO), General Relativity and Quantum Cosmology (gr-qc), and High Energy Physics - Theory (hep-th). Authored by Ezra Msolla and Ayngaran Thavanesan, the 16-page study presents a theoretical framework to better understand the spectral shape of gravitational waves generated during the inflationary period of the early universe. This is expected to yield more detailed insights into the universe’s initial conditions from Cosmic Microwave Background (CMB) observational data.
