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 …

An 800-million-solar-mass black hole in a significantly neutral Universe at a redshift of 7.5
Quasars are the most luminous non-transient objects known and as a result they enable
studies of the Universe at the earliest cosmic epochs. Despite extensive efforts, however, the …
