![]() The joint effect of RPS and merging, according to our simulations, is not significantly different from pure ram pressure effects. These three galaxies show clear evidence of ram pressure stripping due to the cluster medium as found in previous H I imaging studies. The wake of merging galaxies in the ICM typically has a third to half the star mass seen in the non-merging galaxies and 5% to 10 % less gas mass. In the most extreme case, this constitutes a short-term ($<50$ Myr) SFR increase of 50% over the non-merging galaxies experiencing ram pressure. Furthermore, we vary the properties of the intracluster medium (ICM) in rough steps: The speed of the merging system relative to the ICM between 5 km/s, the ICM density between $10^$/yr of the non-merging galaxies in vacuum). We sample different geometric configurations of the merging systems (edge-on and face-on mergers, different impact parameters). ![]() This method requires that we solve the simultaneous equations that result when Kirchoff’s current law (KCL) is applied at various nodes in an electric circuit. Nodal Analysis: The Nodal Analysis method is used to analyze multi source circuits. In our simulations, we vary mass ratios between 1:4 and 1:8 in a binary merger. Basic DC Circuit Analysis, Basic Electrical and Electronics / By eeeonline. Methods: We make use of the combined N-body/hydrodynamic code GADGET-2. Our goal is to provide an estimate of the combined effect of merging and RPS on stripping efficiency and star formation rate. ![]() Aims: We investigate the effect of ram pressure stripping (RPS) on simulations of merging pairs of gas-rich spiral galaxies.
