Galaxy formation is at the heart of our understanding of cosmic evolution. Although there is a
consensus that galaxies emerged from the expanding matter background by gravitational …

The transformation of cold neutral intergalactic hydrogen into a highly ionized warm plasma
marks the end of the cosmic dark ages and the beginning of the age of galaxies. The details …

Recent JWST observations suggest an excess of z≳ 10 galaxy candidates above most
theoretical models. Here, we explore how the interplay between halo formation time-scales …

The earliest JWST observations have revealed an unexpected abundance of super-early (z>
10), massive () galaxies at the bright-end (M UV≈− 21) of the ultraviolet luminosity function …

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

The high-redshift intergalactic medium (IGM) and the primeval galaxy population are rapidly
becoming the new frontier of extragalactic astronomy. We investigate the IGM properties and …

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 …

We present a new, open source, free, semi-analytic model (SAM) of galaxy formation, Shark,
designed to be highly flexible and modular, allowing easy exploration of different physical …

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 …

In anticipation of the upcoming deployment of the James Webb Space Telescope (JWST),
we present high-redshift predictions by the well-established Santa Cruz semi-analytic …
