Mergers may not be the main channel for galaxy stellar mass growth at redshift $z\gtrsim 5$: Predictions from cosmological hierarchical models and simulations

Hao Fu, Mohammadreza Ayromlou, Francesco Shankar +13

Mergers are a crucial channel of galaxy growth, but their role relative to star formation remains uncertain at high redshift. Here we investigate merger rates and merger-driven ste…
