The first generation of stars, often called Population III (or Pop III), form from metal-free
primordial gas at redshifts z∼ 30 and below. They dominate the cosmic star-formation …

The existence of∼ 109M⊙ supermassive black holes (SMBHs) within the first billion years
of the Universe has stimulated numerous ideas for the prompt formation and rapid growth of …

In recent years, the discovery of massive quasars at has provided a striking challenge to our
understanding of the origin and growth of supermassive black holes in the early Universe …

The detection of quasars at z> 6 unveils the presence of supermassive black holes of a few
billion solar masses. The rapid formation process of these extreme objects remains a …

We present Trinity, a flexible empirical model that self-consistently infers the statistical
connection between dark matter haloes, galaxies, and supermassive black holes (SMBHs) …

Magnetic fields play an important role in astrophysical accretion discs and in the interstellar
and intergalactic medium. They drive jets, suppress fragmentation in star-forming clouds and …

We review the current status of knowledge concerning the early phases of star formation
during cosmic dawn. This includes the first generations of stars forming in the lowest mass …

While large numbers of supermassive black holes have been detected at z> 6, their origin is
still essentially unclear. Numerical simulations have shown that the conditions for the …

We study the initial mass function (IMF) and hosting halo properties of intermediate-mass
black holes (IMBHs, 104− 6 M⊙) formed inside metal-free, UV-illuminated atomic-cooling …

Magnetic fields play an important role for the formation of stars in both local and high-redshift
galaxies. Recent studies of dynamo amplification in the first dark matter haloes suggest that …
