Quantifying collision-driven mass loss in supermassive star formation: the role of stellar structure and accretion
P. A. Solar, B. Reinoso, D. R. G. Schleicher +1
Observations of high-redshift galaxies with JWST have renewed interest in scenarios where supermassive stars form via runaway stellar collisions in dense clusters, yet the impact o…
Tidal locking as a negative feedback on Earth-like planetary dynamos: Consequences for magnetic shielding and habitability
J. P. Hidalgo, D. R. G Schleicher
We investigate how tidal locking affects the magnetic field generation and magnetospheric protection of Earth-like planets orbiting the habitable zone of M dwarfs. While the role o…
Little Red Dot progenitors from Compact Starbursts: A Natural Path to Early AGN Formation
Matías Liempi, Muhammad A. Latif, Dominik R. G. Schleicher
The recent discovery of Little Red Dots (LRDs) by the James Webb Space Telescope has challenged traditional models of early galaxy and black hole co-evolution. The nature of these…
Formation of intermediate-mass black holes in young massive clusters detected with JWST: analytic mass estimates
Viola Bocchi, Matías Liempi, Dominik R. G. Schleicher
The James Webb Space Telescope (JWST) has revealed a population of dense stellar systems at high redshift, including the "Cosmic Gems" arc () and the "Firefly Sparkle"…
Massive star clusters detected by JWST as natural birth places to form intermediate-mass black holes
Dominik R. G. Schleicher, Matías Liempi, Mirek Giersz +11
The James Webb Space Telescope (JWST) has detected, through gravitational lensing, several young massive star clusters (YMCs), which are considered as relevant building blocks of h…
Efficient black hole seed formation in low metallicity and dense stellar clusters with implications for JWST sources
M. C. Vergara, A. Askar, F. Flammini Dotti +7
Recent observations with the James Webb Space Telescope (JWST) reveal young massive clusters (YMCs) as key building blocks of early galaxies. They are not only important constituen…
Formation of supermassive stars in the first stellar clusters: Dependence on the gas temperature
P. A. Solar, B. Reinoso, D. R. G. Schleicher +2
The origin of supermassive black holes is an open question that has been explored considering gas- and collision-based formation channels to explain the high number of quasars obse…
The supermassive black hole population from seeding via collisions in Nuclear Star Clusters
M. Liempi, D. R. G. Schleicher, A. Benson +2
The coexistence of nuclear star clusters (NSCs) and supermassive black holes (SMBHs) in galaxies with stellar masses M, the scaling relations between their p…
Gravitational collapse at low to moderate Mach numbers: The relationship between star formation efficiency and the fraction of mass in the massive object
Jorge Saavedra-Bastidas, Dominik R. G. Schleicher, Ralf S. Klessen +7
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 form…
Supermassive black hole formation via collisions in black hole clusters
Benjamin Gaete, Dominik R. G. Schleicher, Alessandro Lupi +3
More than 300 supermassive black holes have been detected at redshifts larger than 6, and they are abundant in the centers of local galaxies. Their formation mechanisms, however, a…
Turbulence and the characteristics of circumstellar discs
R. Riaz, D. R. G. Schleicher, S. Vanaverbeke +2
We investigate the properties of circumstellar discs (CDs) produced in hydrodynamical simulations of gravoturbulent core collapse considering Kolmogorov and Burger-type turbulence.…
A model for the infrared-radio correlation of main-sequence galaxies at GHz frequencies and its variation on redshift and stellar mass
J. Schober, M. T. Sargent, R. S. Klessen +1
The infrared-radio correlation (IRRC) of star-forming galaxies can be used to estimate their star formation rate (SFR) based on the radio continuum luminosity at MHz-GHz frequencie…
Global instability by runaway collisions in nuclear stellar clusters: Numerical tests of a route for massive black hole formation
M. C. Vergara, A. Escala, D. R. G. Schleicher +1
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…
The effects of a background potential in star cluster evolution: a delay in the relaxation time-scale and runaway collision processes
B. Reinoso, D. R. G. Schleicher, M. Fellhauer +2
Runaway stellar collisions in dense star clusters are invoked to explain the presence of very massive stars or blue stragglers in the center of those systems. This process has also…
Formation of massive seed black holes via collisions and accretion
T. C. N. Boekholt, D. R. G. Schleicher, M. Fellhauer +4
Models aiming to explain the formation of massive black hole seeds, and in particular the direct collapse scenario, face substantial difficulties. These are rooted in rather ad hoc…
Galactic synchrotron emission and the FIR-radio correlation at high redshift
Jennifer Schober, Dominik R. G. Schleicher, Ralf S. Klessen
Galactic magnetic fields in the local Universe are strong and omnipresent. There is mounting evidence that galaxies were magnetized already in the early Universe. Theoretical scena…
