Effect of the cosmological transition to metal-enriched star-formation on the hydrogen 21-cm signal
Mattis Magg, Itamar Reis, Anastasia Fialkov +6
Mapping Cosmic Dawn with 21-cm tomography offers an exciting new window into the era of primordial star formation. However, self-consistent implementation of both the process of st…
HERA Phase I Limits on the Cosmic 21-cm Signal: Constraints on Astrophysics and Cosmology During the Epoch of Reionization
The HERA Collaboration, Zara Abdurashidova, James E. Aguirre +81
Recently, the Hydrogen Epoch of Reionization Array (HERA) collaboration has produced the experiment's first upper limits on the power spectrum of 21-cm fluctuations at z~8 and 10.…
Shot noise and scatter in the star formation efficiency as a source of 21-cm fluctuations
Itamar Reis, Rennan Barkana, Anastasia Fialkov
The 21-cm signal from cosmic dawn and the epoch of reionization (EoR) probes the characteristics of the high redshift galaxy population. Many of the astrophysical properties of gal…
The subtlety of Ly-a photons: changing the expected range of the 21-cm signal
Itamar Reis, Anastasia Fialkov, Rennan Barkana
We present the evolution of the 21-cm signal from cosmic dawn and the epoch of reionization (EoR) in an upgraded model including three subtle effects of Ly-a radiation: Ly-a heatin…
