The STARfall pathway: forging intermediate-mass black holes through stellar collisions in dense star clusters
Filippo Simonato, Manuel Arca Sedda, Taeho Ryu +15
Intermediate-mass black holes (IMBHs, ) are elusive objects bridging the gap between stellar-mass and supermassive black holes, whose o…
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…
Evolution of star clusters with initial bulk rotation via N-body simulations
Abylay Bissekenov, Xiaoying Pang, Albrecht Kamlah +6
Young star clusters can inherit bulk rotation from the molecular clouds from which they have formed. This rotation can affect the long-term evolution of a star cluster and its cons…
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…
Growth of Seed Black Holes in Galactic Nuclei
Rainer Spurzem, Francesco Rizzuto, Manuel Arca Sedda +5
The evolution of dense star clusters is followed by direct high-accuracy N-body simulation. The problem is to first order a gravitational N-body problem, but stars evolve due to as…
The Dragon-II simulations -- II. Formation mechanisms, mass, and spin of intermediate-mass black holes in star clusters with up to 1 million stars
Manuel Arca Sedda, Albrecht W. H. Kamlah, Rainer Spurzem +4
The processes that govern the formation of intermediate-mass black holes (IMBHs) in dense stellar clusters are still unclear. Here, we discuss the role of stellar mergers, star-BH…
The Dragon-II simulations -- I. Evolution of single and binary compact objects in star clusters with up to 1 million stars
Manuel Arca Sedda, Albrecht W. H. Kamlah, Rainer Spurzem +7
We present the first results of the \textsc{Dragon-II} simulations, a suite of 19 -body simulations of star clusters with up to stars, with up to of them initially…
Evolution of open clusters with or without black holes
B. Shukirgaliyev, P. Berczik, A. Otebay +6
Binary black holes (BHs) can be formed dynamically in the centers of star clusters. The high natal kicks for stellar-mass BHs used in previous works made it hard to retain BHs in s…
PHANGS-JWST First Results: A combined HST and JWST analysis of the nuclear star cluster in NGC 628
Nils Hoyer, Francesca Pinna, Albrecht W. H. Kamlah +28
We combine archival HST and new JWST imaging data, covering the ultraviolet to mid-infrared regime, to morphologically analyze the nuclear star cluster (NSC) of NGC 628, a grand-de…
