Beyond21: A Global Framework for Cosmic Dawn and Reionization Within and Beyond the Standard Model
Omer Zvi Katz
Observations of the Cosmic Dawn (CD) and Epoch of Reionization (EoR) are steadily improving, opening new opportunities to study early galaxies through complementary probes. To enab…
Closing in on Pop-III Stars: Constraints and Predictions Across the Spectrum
Omer Zvi Katz, Diego Redigolo, Tomer Volansky
The absence of direct high redshift observations poses a significant challenge in understanding the properties of first stars. Nonetheless, the cumulative effect of entire stellar…
Mitigating Astrophysical Uncertainties in 21-cm Cosmology
Omer Zvi Katz
The light of the first astrophysical objects is expected to leave an imprint on the global 21-cm signal as it heats, excites, and ionizes neutral hydrogen. This dependence on early…
Probing New Physics at Cosmic Dawn with 21-cm Cosmology
Omer Zvi Katz, Nadav Outmezguine, Diego Redigolo +1
21-cm cosmology provides an exciting opportunity to probe new physics dynamics in the early universe. In particular, a tiny sub-component of dark matter that interacts strongly wit…
