Ram pressure stripping (RPS) has a non-negligible impact on the gas content of cluster galaxies. We used the semi-analytic model GAEA and the hydro-simulation TNG to investigate whether cluster galaxies suffer from strong RPS that is sufficient to remove a significant fraction of their gas during the first pericentric passage. We estimated that a ram pressure of 10 −10.5 , 10 −12 , 10 −13.5 g cm −1 s −2 can remove 90%, 50%, and 20% of the cold gas reservoir from low-mass galaxies with 9 15).
