The burgeoning rise of the 21-cm forest I: constraints on the optical depth of the intergalactic medium at
Chanasorn Kongprachaya, Gianni Bernardi, Emilio Ceccotti +3
The redshifted 21-cm line is a promising probe of the Epoch of Reionization, during which the first generation of stars ionized the InterGalactic Medium (IGM). We aimed to constrai…
Square Kilometer Array Synergies for the Epoch of Reionization and Cosmic Dawn
Anirban Chakraborty, Tirthankar R. Choudhury, Kanan K. Datta +15
Synergies with other instruments will be essential in making, verifying, and interpreting a detection of the cosmic 21-cm signal from the Epoch of Reionization (EoR) and Cosmic Daw…
Semi-analytical approach to Ly multiple-scattering in 21-cm signal simulations
Jordan Flitter, Julian B. Muñoz, Andrei Mesinger
A crucial physical quantity in determining the 21-cm signal during cosmic dawn is the inhomogeneous background of Ly photons originating from the first galaxies. As these photo…
21cmEMUv3: a hybrid diffusion-LSTM emulator of 21cmFAST summary observables
Daniela Breitman, Andrei Mesinger, Steven G. Murray +2
We are witnessing a surge in observations of the cosmic dawn (CD) and epoch of reionisation (EoR), driving an increasing demand for fast and robust theoretical interpretation frame…
Characterizing Lyman alpha emission from high-redshift galaxies
Samuel Gagnon-Hartman, Andrei Mesinger, Ivan NikoliÄ +2
The Lyman (Ly) line from high-redshift galaxies is a powerful probe of the Epoch of Reionization (EoR). Neutral hydrogen in the intergalactic medium (IGM) can significantl…
First Results from HERA Phase II
The HERA Collaboration, Zuhra Abdurashidova, Tyrone Adams +83
We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Ar…
