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 …

We introduce the thesan project, a suite of large volume () radiation-magnetohydrodynamic
simulations that simultaneously model the large-scale statistical properties of the …

The 21 cm signal from the dark ages provides a potential new probe of fundamental
cosmology. While exotic physics could be discovered, here we quantify the expected …

We report the most sensitive upper limits to date on the 21 cm epoch of reionization power
spectrum using 94 nights of observing with Phase I of the Hydrogen Epoch of Reionization …

We report upper limits on the Epoch of Reionization 21 cm power spectrum at redshifts 7.9
and 10.4 with 18 nights of data (∼ 36 hr of integration) from Phase I of the Hydrogen Epoch …

ABSTRACT A new upper limit on the 21 cm signal power spectrum at a redshift of z≈ 9.1 is
presented, based on 141 h of data obtained with the Low-Frequency Array (LOFAR). The …

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 …

The formation of the first galaxies during cosmic dawn and reionization (at redshifts z= 5–
30), triggered the last major phase transition of our universe, as hydrogen evolved from cold …

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 …
