The other important observation we need to make about spiral galaxies is that galaxies do not rotate rigidly (with a constant angular velocity), but to a good approximation each region rotates with the same tangential velocity. The properties of random self-propagating star formation and constant tangential velocity are incorporated into GalaxyApp as follows. Imagine dividing a galaxy into concentric rings which are divided into cells of equal size (see Figure 19.1). Initially, a small number of cells are activated. Each cell corresponds to a region of space that is the size of a giant molecular cloud and moves with the same tangential velocity v. The angular velocity is given by ```, where r is the distance of the ring from the center of the galaxy. At each time step, the active cells activate neighboring cells with probability p and then became inactive. Then the rings are rotated, and the process is repeated again in the next time step. At each time step, cells that have been active

另一个重要的观察,我们需要作出关于螺旋星系是宇宙不旋转严格(以恒定角速度) ,但有一个良好的逼近各地区轮流担任相同的切向速度。的属性随机自我传播的恒星形成和不断的切向速度纳入GalaxyApp如下。试想划分一个星系到同心圆环其中分为细胞同等规模(见图1月19日) 。起初,有少数细胞被激活。每个细胞相当于一个区域的空间,这是一个巨大的规模和行动分子云与同切向速度诉角速度给出了`` ` ,其中r是距离环的中心银河。在每个时间步长,积极细胞激活邻近细胞概率p ,然后成为无效。那么,环转动,整个过程是再次重申在未来的时间步长。在每个时间步长,细胞,一直积极在过去15time步骤显示为填补箱,与每个方块大小成反比的时间,因为细胞变得活跃。更详细的模拟图,并在1月19日的计划。一个典型的星系产生GalaxyApp是如图2月19日。
我们简要地讨论了星系并不意味着让你信服,所提出的机制舒尔曼和Seiden是正确的。而我们的目的是表明如何替代的观点提出新的方法可以在不同的领域。所产生的图像的计算机模拟显示银河系模型预料的特点,并已研究开发的动力进一步研究的天体物理学家和天文学家。
