Tomography of the Cosmic Dawn and Reionization Eras with Multiple Tracers
Abstract
We advocate a multi-tracer, large-scale approach to study the reionization and cosmic dawn eras. We highlight the line intensity mapping technique to trace the multi-phase reionization topology on large scales and reionization history in detail. We also advocate for Lyα tomography mapping as an additional probe besides 21cm of the cosmic dawn era.
