Emulating the Global 21-cm Signal from Cosmic Dawn and Reionization
Aviad Cohen, Anastasia Fialkov, Rennan Barkana +1
The 21-cm signal of neutral hydrogen is a sensitive probe of the Epoch of Reionization (EoR) and Cosmic Dawn. Currently operating radio telescopes have ushered in a data-driven era…
Results from EDGES High-Band: III. New Constraints on Parameters of the Early Universe
Raul A. Monsalve, Anastasia Fialkov, Judd D. Bowman +5
We present new constraints on parameters of cosmic dawn and the epoch of reionization derived from the EDGES High-Band spectrum ( MHz). The parameters are probed by evaluat…
Constraining Baryon--Dark Matter Scattering with the Cosmic Dawn 21-cm Signal
Anastasia Fialkov, Rennan Barkana, Aviad Cohen
The recent detection of an anomalously strong 21-cm signal of neutral hydrogen from Cosmic Dawn by the EDGES Low-Band radio experiment can be explained if cold dark matter particle…
Reconstructing the nature of the first cosmic sources from the anisotropic 21-cm signal
Anastasia Fialkov, Rennan Barkana, Aviad Cohen
The redshifted 21-cm background is expected to be a powerful probe of the early Universe, carrying both cosmological and astrophysical information from a wide range of redshifts. I…
