The Cosmic Dawn and Reionization epochs remain a fundamental but challenging frontier of astrophysics and cosmology. We advocate a large-scale, multi-tracer approach to develop a comprehensive understanding of the physics that led to the formation and evolution of the first stars and galaxies. We highlight the line intensity mapping technique to trace the multi-phase reionization topology on large scales, and measure reionization history in detail. Besides 21cm, we advocate for Lya tomography mapping during the epoch of Wouthuysen-Field coupling as an additional probe of the cosmic dawn era.

  1. A New Boundary Condition on Reionization

    astro-ph.CO 2025-09 conditional novelty 6.0 of 10

    A zero-lag Pearson correlation between 21-cm and line-intensity maps is predicted to drop sharply at ionized fractions of 1-10%, providing a novel marker for the onset of reionization.

  2. Disentangling Target Lines from Interlopers and Continuum with Neural Networks: A SPHEREx Intensity Mapping Case Study

    astro-ph.CO 2025-09 conditional novelty 6.0 of 10

    A moment-network approach separates target and interloper line power spectra from continuum in SPHEREx-like intensity maps, recovering H-alpha to within 6% in the most realistic tested setup.

  3. Reading Between the Lines: Forward Modeling Dust, Continuum, and Spectral Cleaning for Multi-Line Intensity Mapping

    astro-ph.GA 2026-07 conditional novelty 5.0 of 10

    Using a SAM-based mock, multi-line intensity-mapping cross-power spectra show dust acts as a line-pair- and redshift-dependent suppression, and PCA cleaning with about 20 modes best balances line recovery against cont...
