Early galaxy formation and its large-scale effects
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 …

A census of baryons in the Universe from localized fast radio bursts
More than three-quarters of the baryonic content of the Universe resides in a highly diffuse
state that is difficult to detect, with only a small fraction directly observed in galaxies and …

Constraining the evolution of the ionizing background and the epoch of reionization with z∼ 6 quasars. II. A sample of 19 quasars
We study the evolution of the ionization state of the intergalactic medium (IGM) at the end of
the reionization epoch using moderate-resolution spectra of a sample of 19 quasars at 5.74< …

In the beginning: the first sources of light and the reionization of the universe
The formation of the first stars and quasars marks the transformation of the universe from its
smooth initial state to its clumpy current state. In popular cosmological models, the first …
