Globular cluster numbers in dark matter haloes in a dual formation scenario: an empirical model within EMERGE

Lucas M. Valenzuela, Benjamin P. Moster, Rhea-Silvia Remus +2

We present an empirical model for the number of globular clusters (GCs) in galaxies based on recent data showing a tight relationship between dark matter halo virial masses and GC…

EMERGE: Constraining merging probabilities and timescales of close galaxy pairs

Joseph A. O'Leary, Benjamin P. Moster, Eva Krämer

Theoretical models are vital for exploring the galaxy merger process, which plays a crucial role in the evolution of galaxies. Recent advances in modelling have placed tight constr…

EMERGE: Empirical predictions of galaxy merger rates since $z \sim 6$

Joseph A. O'Leary, Benjamin P. Moster, Thorsten Naab +1

We explore the galaxy-galaxy merger rate with the empirical model for galaxy formation, Emerge. On average, we find that between $2$ per cent and $20$ per cent of massive galaxies…
