Star formation concentration as a tracer of environmental quenching in action: a study of the scp>eagle/scp> and scp>c-eagle/scp> simulations ...
We study environmental quenching in the eagle/c-eagle cosmological hydrodynamic simulations over the last 11 Gyr (i.e. z = 0-2). The simulations are compared with observations from the SAMI Galaxy Survey at z = 0. We focus on satellite galaxies in galaxy groups and clusters (â M200 2 Gyr). The simul...

| Summary: | We study environmental quenching in the eagle/c-eagle cosmological hydrodynamic simulations over the last 11 Gyr (i.e. z = 0-2). The simulations are compared with observations from the SAMI Galaxy Survey at z = 0. We focus on satellite galaxies in galaxy groups and clusters (â M200 2 Gyr). The simulated galaxies at higher redshift (z = 0.7 ∼2) experience faster quenching (median tquench < 2 Gyr). At z â 1-2 galaxies undergoing environmental quenching have decreased sSFR across the entire galaxy with no 'outside-in' quenching signatures and a narrow range of C-index, showing that on average environmental quenching acts differently than at z â 1. ... |
