We review the physics and phenomenology of wave dark matter: a bosonic dark matter
candidate lighter than about 30 eV. Such particles have a de Broglie wavelength exceeding …

Over the past decade, increasingly robust estimates of the dense molecular gas content in
galaxy populations between redshift z= 0 and the peak of cosmic galaxy/star formation (z∼ …

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

The presence of excess scatter in the Ly-α forest at z∼ 5.5, together with the existence of
sporadic extended opaque Gunn-Peterson troughs, has started to provide robust evidence …

After stars formed in the early Universe, their ultraviolet light is expected, eventually, to have
penetrated the primordial hydrogen gas and altered the excitation state of its 21-centimetre …

Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

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 …

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 …

The cosmic radio-frequency spectrum is expected to show a strong absorption signal
corresponding to the 21-centimetre-wavelength transition of atomic hydrogen around …

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 …
