The fragility of thin discs in galaxies -- II. Thin discs as tracers of the assembly history of galaxies
Pablo M. Galán-de Anta, Pedro R. Capelo, Eugene Vasiliev +4
Thin galactic discs and nuclear stellar discs (NSDs) are fragile structures that can be easily disturbed by merger events. By studying the age of the stellar populations in present…
Direct formation of massive black holes via dynamical collapse in metal-enriched merging galaxies at : fully cosmological simulations
Lucio Mayer, Pedro R. Capelo, Lorenz Zwick +1
We present the results of the first fully cosmological hydrodynamical simulations studying the merger-driven model for massive black hole (BH) seed formation via direct collapse. U…
Stellar cluster formation in a Milky Way-sized galaxy at z>4 -- II. A hybrid formation scenario for the nuclear star cluster and its connection to the nuclear stellar ring
Floor van Donkelaar, Lucio Mayer, Pedro R. Capelo +3
Nuclear star clusters (NSCs) are massive star clusters found in the innermost region of most galaxies. While recent studies suggest that low-mass NSCs in dwarf galaxies form largel…
The fragility of thin discs in galaxies -- I. Building tailored N-body galaxy models
Pablo M. Galán-de Anta, Eugene Vasiliev, Marc Sarzi +6
Thin stellar discs on both galactic and nuclear, sub-kpc scales are believed to be fragile structures that would be easily destroyed in major mergers. In turn, this makes the age-d…
