Dynamical constraints on the S2 (S0-2) star possible companions
Rodrigo P. Silva, Alexandre C. M. Correia, Tjarda C. N. Boekholt +1
The center of the Galaxy harbors a supermassive black hole, Sgr\,A*, which is surrounded by a massive star cluster known as the S-cluster. The most extensively studied star in this…
Capture of field stars by dark substructures
Jorge Peñarrubia, Raphaël Errani, Matthew G. Walker +2
We use analytical and -body methods to study the capture of field stars by gravitating substructures moving across a galactic environment. The majority of stars captured by a su…
Gas Assisted Binary Black Hole Formation in AGN Discs
Henry Whitehead, Connar Rowan, Tjarda Boekholt +1
We investigate close encounters by stellar mass black holes (BHs) in the gaseous discs of active galactic nuclei (AGN) as a potential formation channel of binary black holes (BBHs)…
Stirred, not shaken: Star cluster survival in the slingshot scenario
D. Matus Carrillo, M. Fellhauer, T. Boekholt +2
We investigate the effects of an oscillating gas filament on the dynamics of its embedded stellar clusters. Motivated by recent observational constraints, we model the host gas fil…
Black Hole Binary Formation in AGN Discs: From Isolation to Merger
Connar Rowan, Tjarda Boekholt, Bence Kocsis +1
Motivated by the increasing number of detections of merging black holes by LIGO-VIRGO-KAGRA, black hole (BH) binary mergers in the discs of active galactic nuclei (AGN) is investig…
Effect of mass loss due to stellar winds on the formation of supermassive black hole seeds in dense nuclear star clusters
Arpan Das, Dominik R. G. Schleicher, Shantanu Basu +1
The observations of high redshifts quasars at have revealed that supermassive black holes (SMBHs) of mass were already in place within…
Stellar collisions in flattened and rotating Pop. III star clusters
M. Z. C. Vergara, D. R. G. Schleicher, T. C. N. Boekholt +4
Fragmentation often occurs in disk-like structures, both in the early Universe and in the context of present-day star formation. Supermassive black holes (SMBHs) are astrophysical…
Formation of supermassive black hole seeds in nuclear star clusters via gas accretion and runaway collisions
Arpan Das, Dominik R. G. Schleicher, Nathan W. C. Leigh +1
More than two hundred supermassive black holes (SMBHs) of masses have been discovered at . One promising pathway for the formation o…
Formation of SMBH seeds in Pop III star clusters through collisions : the importance of mass loss
P. J. Alister Seguel, D. R. G. Schleicher, T. C. N. Boekholt +2
Runaway collisions in dense clusters may lead to the formation of supermassive black hole (SMBH) seeds, and this process can be further enhanced by accretion, as recent models of S…
Formation of massive black holes via collisions and accretion
D. R. G. Schleicher, M. A. Fellhauer, T. Boekholt +13
To explain the observed population of supermassive black holes at z~7, very massive seed black holes or, alternatively, super-Eddington scenarios are needed to reach final masses o…
Collisions in Primordial Star Clusters: Formation Pathway for intermediate mass black holes
B. Reinoso, D. R. G. Schleicher, M. Fellhauer +2
Collisions were suggested to potentially play a role in the formation of massive stars in present day clusters, and have likely been relevant during the formation of massive stars…
Dynamical Ejections of Stars due to an Accelerating Gas Filament
Tjarda C. N. Boekholt, Amelia M. Stutz, Michael Fellhauer +2
Observations of the Orion-A integral shaped filament (ISF) have shown indications of an oscillatory motion of the gas filament. This evidence is based on both the wave-like morphol…
