Observations of environmental quenching in groups in the 11 Gyr since z=2.5: different quenching for central and satellite galaxies

Tomer Tal, Avishai Dekel, Pascal Oesch +16

We present direct observational evidence for star formation quenching in galaxy groups in the redshift range 0<z<2.5. We utilize a large sample of nearly 6000 groups, selected by f…
