The first generation of stars, often called Population III (or Pop III), form from metal-free
primordial gas at redshifts z∼ 30 and below. They dominate the cosmic star-formation …

The redshifted 21 cm line is an emerging tool in cosmology, in principle permitting three-
dimensional surveys of our universe that reach unprecedentedly large volumes, previously …

Abstract Using the Murchison Widefield Array (MWA), the low-frequency Square Kilometre
Array precursor located in Western Australia, we have completed the GaLactic and …

We discuss new constraints on the epoch of cosmic reionization and test the assumption that
most of the ionizing photons responsible arose from high-redshift star-forming galaxies …

Abstract The Hydrogen Epoch of Reionization Array (HERA) is a staged experiment to
measure 21 cm emission from the primordial intergalactic medium (IGM) throughout cosmic …

Astronomical wide-field imaging of interferometric radio data is computationally expensive,
especially for the large data volumes created by modern non-coplanar many-element …

We compute the spherically averaged power spectrum from four seasons of data obtained
for the Epoch of Reionization (EoR) project observed with the Murchison Widefield Array …

We describe the motivation and design details of the 'Phase II'upgrade of the Murchison
Widefield Array radio telescope. The expansion doubles to 256 the number of antenna tiles …

The properties of the first galaxies, expected to drive the Cosmic Dawn and the Epoch of
Reionization, are encoded in the 3D structure of the cosmic 21-cm signal. Parameter …

We present the first limits on the Epoch of Reionization 21 cm H i power spectra, in the
redshift range z= 7.9–10.6, using the Low-Frequency Array (LOFAR) High-Band Antenna …
