Our research focuses on determining the dynamical orbital parameters associated with galaxy collisions. We are accomplishing this by optimizing numerical models of galactic interactions with astronomical observations of colliding galaxies and measuring the uncertainty in the parameter space of these models. This paper will focus on how we compare our numerical models to observed colliding galaxies. We create gravitational n -body models that capture the tidal distortions from galaxy collisions. The final particle positions are then processed to create model images that have realistic intensity profiles and resolutions. We compare the model’s output with the astronomical images to obtain an objective machine score that should reflect the fitness of the model. To test our scoring methods, we then compare our machine scores to the human-scores obtained from the citizen science project Galaxy Zoo: Mergers.

优化碰撞星系的数值模拟。二。将模拟与天文观测进行比较

我们的研究重点是确定与银河系碰撞相关的动力学轨道参数。我们通过使用碰撞星系的天文观测值优化银河相互作用的数值模型并测量这些模型的参数空间中的不确定性来实现这一目标。本文将重点讨论如何将数值模型与观测到的碰撞星系进行比较。我们创建了重力n体模型，该模型捕获了来自银河系碰撞的潮汐变形。然后处理最终的粒子位置，以创建具有逼真的强度轮廓和分辨率的模型图像。我们将模型的输出与天文图像进行比较，以获得客观的机器分数，该分数应反映模型的适用性。为了测试我们的计分方法，
