Direct N-body simulations of rotating and extremely massive Population III star clusters
Kai Wu, Ataru Tanikawa, Francesco Flammini Dotti +6
Aims. We present eight direct N-body simulations with NBODY6++GPU of extremely massive, initially rotating Population III star clusters with 1.01 x 10^5 stars. Methods. Our models…
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…
Constraints on dynamically-formed massive black holes in Little Red Dots from X-ray non-detections
M. Liempi, D. R. G. Schleicher, M. A. Latif +4
The existence of massive, compact galaxies (Little Red Dots, LRDs) at challenges early structure formation models, suggesting rapid stellar and black hole (BH) assembly.…
Formation and growth of intermediate-mass black holes in dense star clusters: Lessons from N-body and MOCCA Monte Carlo Simulations
Abbas Askar, Marcelo C. Vergara, Sohaib Ali
Dense star clusters are promising nurseries for the formation and growth of intermediate-mass black holes (IMBHs; ), with increasing observation…
On the Fate of Little Red Dots
Andres Escala, Lucas Zimmermann, Sebastian Valdebenito +3
We study the stability and possible fates of Little Red Dots, under the stellar-only interpretation of their observational features. This is performed by a combination of analyzing…
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…
Rapid formation of a very massive star >50000 and subsequently an IMBH from runaway collisions. Direct N-body and Monte Carlo simulations of dense star clusters
Marcelo C. Vergara, Abbas Askar, Albrecht W. H. Kamlah +15
Context. We present simulations of a massive young star cluster using \textsc{Nbody6++GPU} and \textsc{MOCCA}. The cluster is initially more compact than previously published model…
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…
Efficiency of black hole formation via collisions in stellar systems: An analysis of data from simulations and observations
M. C. Vergara, D. R. G. Schleicher, A. Escala +7
This paper explores the theoretical relation between star clusters and black holes within, focusing on the potential role of nuclear star clusters (NSCs), globular clusters (GCs),…
