A new analytic ram pressure profile for satellite galaxies

We present a new analytic fitting profile to model the ram pressure exerted over satellite galaxies on different environments and epochs. The is built using information of gas particle distribution in hydrodynamical simulations groups clusters measure directly. show that predictions obtained by previously introduced $\beta$-profile can not consistently reproduce dependence halocentric distance redshift for given halo mass. It features systematic underestimation predicted at high redshifts ($z > 1.5$), which increases towards central regions haloes it independent mass, reaching differences larger than two decades satellites $r<0.4R_\mathrm{vir}$. This behaviour reverses as decreases, featuring an increasing over-estimation with $z=0$. As alternative, we introduce universal profiles recover redshift. analyse impact our galaxy properties applying semi-analytic formation evolution top simulations. experiencing large amounts cumulative stripping typically have low stellar masses ($M_\star \leq 10^{9.5} \text{M}_\odot$). Besides, their specific star histories depend modelling applied, particularly 1.5$).
