Dark Radiation production in axion misalignment mechanisms and the cosmological tensions
José MarÃa Pérez-Poyatos, Veronica Sanz
We investigate the production of dark radiation (DR) from axions and axion-like particles (ALPs) as potential origins of dark matter. Focusing on the dark matter misalignment mecha…
