物理学哲学博士-天体物理学与宇宙学

天体物理学和宇宙学涉及控制天文物体行为的物理过程的研究，以及整个宇宙的起源，演化，组成和命运的研究。我们小组正在解决物理学中许多最棘手和根本未解决的问题。宇宙中的大部分物质不是由我们已知的标准模型粒子构成，而是由宇宙中的暗物质代替了宇宙的新组成部分。到目前为止，暗物质已经通过其引力效应被检测到，但是要解密其性质，就需要测量其与正常物质的相互作用。就在15年前，未知的宇宙能量密度的主要成分。暗能量的作用在于加速宇宙膨胀和质量扰动增长的变化。要确定暗能量的性质，将需要进行实验，以前所未有的精度测量其作为红移函
Astrophysics and Cosmology involve the study of the physical processes that govern the behavior of astronomical objects, and the study of the origin, evolution, composition, and fate of the Universe as a whole. Many of the most vexing and fundamental unsolved problems in physics are being tackled by our group. The majority of the matter in the Universe is not made of the standard model particles we know, but instead of a new component of the Universe, dark matter. So far, dark matter has been detected through its gravitational effects, but deciphering its nature will require measuring its interaction with normal matter. The dominant component of the energy density of the Universe was unknown just 15 years ago. Dark energy makes its effect felt in the acceleration of the expansion of the Universe and the change in the growth of mass perturbations. Determining the nature of dark energy will require experiments that can measure both its effects as a function of redshift with unprecedented precision. Modern cosmology relies on a period of inflation in the early Universe to solve the horizon problem and to provide the seeds of structure formation. Detection of the gravitational waves generated in inflation is essential to validating the standard model of cosmology.
