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 …

Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

Massive black holes (MBHs) inhabit galactic centres, and power luminous quasars and
active galactic nuclei, shaping their cosmic environment with the energy they produce. The …

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 …

Understanding the formation and growth of supermassive black holes (SMBHs) at high
redshift represents a major challenge for theoretical models. In this work, we investigate the …

Observations of hyper-luminous quasars at z> 6 reveal the rapid growth of supermassive
black holes (SMBHs) whose origin is still difficult to explain. Their progenitors may have …

We use the moving-mesh code arepo to investigate the effects of different levels of rotation
and turbulence on the fragmentation of primordial gas and the formation of Population III …

Direct collapse black hole (DCBH) formation with mass≳ 105 M⊙ is a promising scenario
for the origin of high-redshift supermassive black holes. It has usually been supposed that …

Possible formation scenarios of supermassive black holes (BHs) in the early universe
include rapid growth from less massive seed BHs via super-Eddington accretion or runaway …

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 …
