Disentangling the formation mechanisms of nuclear star clusters
Katja Fahrion, Ryan Leaman, Mariya Lyubenova +1
Nuclear star clusters (NSCs) are massive star clusters found ubiquitously in the centres of galaxies, from the dwarf regime to massive ellipticals and spirals. The fraction of nucl…
On the link between nuclear star cluster and globular cluster system mass, nucleation fraction and environment
Ryan Leaman, Glenn van de Ven
We present a simple model for the host mass dependence of the galaxy nucleation fraction (), the galaxy's nuclear star cluster (NSC) mass and the mass in its surviving glo…
Cross-checking SMBH mass estimates in NGC 6958 -- I: Stellar dynamics from adaptive optics-assisted MUSE observations
Sabine Thater, Davor Krajnović, Peter M. Weilbacher +9
Supermassive black hole masses (MBH) can dynamically be estimated with various methods and using different kinematic tracers. Different methods have only been cross-checked for a s…
Mass of the dynamically hot inner stellar halo predicts the ancient accreted stellar mass
Ling Zhu, Annalisa Pillepich, Glenn van de Ven +6
Galactic dynamical structures are fossil records of the assembly histories of galaxies. By analyzing the cosmological hydrodynamical simulation TNG50, we find that a dynamical stru…
The Fornax Cluster VLT Spectroscopic Survey III -- Kinematical characterisation of globular clusters across the Fornax galaxy cluster
Avinash Chaturvedi, Michael Hilker, Michele Cantiello +7
The Fornax cluster provides an unparalleled opportunity to investigate in detail the formation and evolution of early-type galaxies in a dense environment. We aim at kinematically…
Observational Evidence of Evolving Dark Matter Profiles at
Gauri Sharma, Paolo Salucci, Glenn van de Ven
We investigate the dark matter halos of 256 star-forming disc-like galaxies at using the KMOS redshift one spectroscopic survey (KROSS). This sample covers the redshifts…
