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 …

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 …

Abstract Recently, the Hydrogen Epoch of Reionization Array (HERA) has produced the
experiment's first upper limits on the power spectrum of 21 cm fluctuations at z∼ 8 and 10 …

The hydrogen 21-cm signal is predicted to be the richest probe of the young Universe,
including those eras known as the cosmic Dark Ages, the Cosmic Dawn (when the first star …

Context. The detection of radio emissions from exoplanets will open up a vibrant new
research field. Observing planetary auroral radio emission is the most promising method to …

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 …

We present a detection of molecular gas emission at z∼ 1–5 using the technique of line
intensity mapping. We make use of a pair of 3 mm interferometric data sets, the first from the …
