论文摘要
我们使用牛顿理论领域内的偶联理论方法，研究了与模式深度内部模式深处的非相关性冷暗物质的演变。我们获得了总密度扰动的一般解决方案，我们还表明，baryon扰动赶上了后期的暗物质扰动，这反过来又使结构的形成成为可能。我们通过考虑转弯事件，物质的崩溃及其病毒化过程来扩展线性扰动分析。
We examine the evolution of non-relativistic cold dark matter gravitationally coupled to baryons with modes deep inside the Hubble radius (sub-horizon regime) using akinetic theory approach within the realm of Newtonian theory. We obtain the general solution for the total density perturbation and we also show that a baryon perturbation catches up with the dark matter perturbation at late times, which in turn makes possible the formation of bound structures. We extend the linear perturbation analysis by considering the turn-around event, the collapse of matter, and its virialization process.
