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…

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…
