The focus of Newcastle particle cosmology is to explore the interaction between cosmology and fundamental particle physics. In the very early universe, the matter underwent a series of phase transitions. Some of these may have involved the condensation of bubbles, rather like the condensation of water droplets in the atmosphere. The basic theory behind bubble nucleation in fundamental particle models is in major need of updating to keep up with new theoretical developments and ideas, such as how bubble may leave behind observational signatures or even form microscopic black holes.In the more recent universe we are still lacking the knowledge of what particles make up most of the dark mass. One possibly is that the dark matter is in the form of a particle wave. We can simulate the formation of structure from wavelike matter using numerical simulations, but to cover the wide range of length scales we need a new approach, and the one we use uses some of the methods borrowed from particle physics. With this, we hope to predict the structures that can be compared with astronomical observations to pin down the nature of dark matter.

纽卡斯尔粒子宇宙学的重点是探索宇宙学与基本粒子物理学之间的相互作用。在早期宇宙中，物质经历了一系列的相变。其中一些可能涉及气泡的凝结，就像大气中水滴的凝结一样。基本粒子模型中气泡成核背后的基本理论需要更新，以跟上新的理论发展和想法，例如气泡如何留下观测信号，甚至形成微观黑洞。在最近的宇宙中，我们仍然缺乏关于什么粒子构成大部分暗物质的知识。一种可能是暗物质是粒子波的形式。我们可以用数值模拟来模拟波动物质的结构形成，但是为了覆盖广泛的长度尺度，我们需要一种新的方法，我们使用的方法使用了一些从粒子物理学中借来的方法。有了这个，我们希望预测可以与天文观测相比较的结构，以确定暗物质的性质。
