The primary purpose of this paper is to see how well a recently proposed new model fits (a)
the position of the baryon acoustic oscillation (BAO) features observed in the large-scale …

ABSTRACT JWST has brought us new insights into Cosmic Dawn with tentative detection of
the unique signatures of metal-free Population III (Pop III) stars, such as strong He II …

The centres of galaxies host nuclear stellar clusters, supermassive black holes, or both. The
origin of this dichotomy is still a mystery. Nuclear stellar clusters are the densest stellar …

Active galactic nuclei (AGNs) in the early Universe are thought to be prominent sources of
energy and ionizing photons that affected the growth of their host galaxy and their …

Context. This paper explores the theoretical relation between star clusters and black holes
within them, focusing on the potential role of nuclear star clusters (NSCS), globular clusters …

Context. Halos with masses in excess of the atomic limit are believed to be ideal
environments in which to form heavy black hole seeds with masses above 10 3 M⊙. In …

Rapid formation of supermassive black holes occurs in dense nuclear star clusters that are
initially gas-dominated. Stellar-mass black hole remnants of the most massive cluster stars …

We present an analytic description of the spherically symmetric gravitational collapse of
radiatively cooling gas clouds, which illustrates the mechanism by which radiative cooling …

Context. High-redshift observations of 10 9 M⊙ supermassive black holes (SMBHs) at z∼ 7
and 'little red dots' that may host over-massive black holes (BHs) at z> 4 suggests the …

The formation of massive objects via gravitational collapse is relevant both for explaining the
origin of the first supermassive black holes and in the context of massive star formation …
