通过结合测试粒子和自洽技术，我们已经开发出一种方法来快速探索星系遭遇的参数空间。我们的方法，在交互式图形程序中实现33该软件可在http：//www.ifa.hawaii.edu/faculty/barnes/research/identikit/.可以用来找到所需的参数，以再现观察到的相互作用的盘星系的形态和运动学。我们测试这个系统的人工数据集的36个等质量合并遇到，并表明，它通常是可以重现这些遭遇的形态和运动学，一个良好的匹配强烈约束的遭遇参数。该软件可在http://www.ifa.hawaii.edu/faculty/barnes/research/identikit/上获得。
By combining test-particle and self-consistent techniques, we have developed a method to rapidly explore the parameter space of galactic encounters. Our method, implemented in an interactive graphics program33 This software is available at http://www.ifa.hawaii.edu/faculty/barnes/research/identikit/., can be used to find the parameters required to reproduce the observed morphology and kinematics of interacting disk galaxies. We test this system on an artificial data set of 36 equal-mass merging encounters, and show that it is usually possible to reproduce the morphology and kinematics of these encounters and that a good match strongly constrains the encounter parameters.
