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 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 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 …

In this review article, we briefly outline our current understanding of the physics associated
with the HI 21-cm signal from cosmic dawn. We discuss different phases of cosmic dawn as …

We introduce a new self-consistent model of galaxy evolution and reionization, astraeus
(seminumerical r A diative tran S fer coupling of galaxy forma T ion and R eionization in N …

We derive constraints on the thermal and ionization states of the intergalactic medium (IGM)
at redshift≈ 9.1 using new upper limits on the 21-cm power spectrum measured by the …

ABSTRACT The Murchison Widefield Array (MWA) team has derived new upper limits on the
spherically averaged power spectrum of the 21-cm signal at six redshifts in the range z≈ 6.5 …

The ARCADE2 and LWA1 experiments have claimed an excess over the cosmic microwave
background (CMB) at low radio frequencies. If the cosmological high-redshift contribution to …
