Research carried out over recent decades has established the main building blocks of the current cosmological model: Dark Matter and Dark Energy, as the two components that dominate the present density, and Inflation, as the leading mechanism for the initial conditions. These building blocks are largely phenomenological concepts — providing an economical description of the universe, while still lacking a proper theoretical understanding. With the new types and the higher precision of observations expected over the next decade, the focus is shifting to developing and testing specific theoretical proposals, as well as using Cosmology as a laboratory for testing fundamental physics. The proposed research will advance two main directions. One will focus on the problem of Cosmic Acceleration and testable aspects of gravity on cosmological scales. The second will study events that took place in the early universe and novel ways of looking for them in the cosmic microwave background (CMB).

近几十年来进行的研究建立了当前宇宙学模型的主要构建基础：暗物质和暗能量，作为主导呈现密度和通货膨胀的两个组成部分，是初始条件的主要机制。这些构建基础在很大程度上是现象学的概念 - 提供了对宇宙的经济描述，同时仍然缺乏适当的理论理解。随着新类型和预期的更高观察结果的较高精度，重点是发展和测试特定的理论建议，并将宇宙学用作测试基本物理学的实验室。拟议的研究将促进两个主要方向。一个人将重点关注宇宙加速度和宇宙学量表的重力方面的问题。第二个将研究在早期宇宙中发生的事件，以及在宇宙微波背景（CMB）中寻找它们的新颖方式。
