Tracing the Quenching Journey across Cosmic Time

Understand

We present the latest version of the GAEA model of galaxy formation.

• Our new model combines (i) an updated treatment of AGN feedback including an improved modelling of cold gas accretion on super-massive BHs and an explicit implementation of quasar winds; and (ii) an improved modelling of cold and hot gas stripping from satellite galaxies.
• We show that our latest model predicts specific SFR distributions that are in remarkable agreement with observational measurements in the local Universe.
• Our updated model predicts quenched fractions that are in very nice agreement with data up to z~3-4, and a turn-over of the number densities of quenched galaxies at low stellar masses that is in qualitative agreement with current observational estimates.
