Major merger fraction compared to previous close pairs count studies and recent simulations. Combined major merger fractions from this work (red squares) are compared to previous estimates from MUSE observations (black squares: Ventou et al. 2017) and other surveys (light blue symbols: de Ravel et al. 2009; Xu et al. 2012; López-Sanjuan et al. 2013; Tasca et al. 2014). The purple and orange solid lines show the predictions from the EAGLE simulations for two different mass ranges (see Qu et al. 2017 for details). Green triangles correspond to the major pair fractions estimated in the ILLUSTRIS simulation (Snyder et al. 2017). Finally, the predictions of pair fractions up to z ∼ 6 with a lower stellar mass cut-off of 109.5 M⊙ from the EMERGE simulations (O’Leary et al., in prep.) are shown with the brown line.
