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…

Updated dark pixel fraction constraints on reionization's end from the Lyman-series forests of XQR-30

Frederick B. Davies, Sarah E. I. Bosman, Valentina D'Odorico +16

The fraction of "dark pixels" in the Ly and other Lyman-series forests at provides a powerful constraint on the end of the reionization process. Any spectral region…

Sample Variance Denoising in Cylindrical 21-cm Power Spectra

Daniela Breitman, Andrei Mesinger, Steven G. Murray +1

State-of-the-art simulations of reionisation-era 21-cm signal have limited volumes, generally orders of magnitude smaller than observations. Consequently, the Fourier modes in comm…

Efficient simulation of discrete galaxy populations and associated radiation fields during the first billion years

James E. Davies, Andrei Mesinger, Steven Murray

Understanding the epochs of cosmic dawn and reionisation requires us to leverage multi-wavelength and multi-tracer observations, with each dataset providing a complimentary piece o…

SKA-ESO Synergies for the Epoch of Reionization and Cosmic Dawn

Andrei Mesinger, Benedetta Ciardi, James E. Davies +2

Mapping out the first billion years using the 21-cm line with the Square Kilometer Array (SKA) will revolutionize our understanding of the cosmic dawn, reionization and the galaxie…

Investigating Primordial Black Hole Accretion through Cosmic Optical Depth

Zi-Xuan Zhang, Junsong Cang, Yu Gao +1

Primordial black holes (PBH) accretion in the late Universe can lead to significant mass growth. A larger mass further accelerates the accretion radiation output for PBHs with init…
