The Earliest Generations of Stars and Galaxies in the Universe

AST-0302148 Santos，MichaelDr.迈克尔·桑托斯将把他的数学和物理科学杰出国际博士后研究奖学金带到英国剑桥大学。他将研究120亿多年前在我们的宇宙中形成的第一批恒星和星系的性质。这些银河系和太阳的原始前驱物质是理解宇宙中随后的发光结构组装的关键，但很难直接观察到。然而，年轻的宇宙在某些方面比我们现在看到的更简单，这使得理论研究可以进入它。他的研究将集中在许多未被探索的方面，即第一批星系如何相互作用，以及它们周围的宇宙是如何相互作用的。特别是，他将研究最小的星系，因为它们都是“矿井中的金丝雀”，早期物理过程最敏感的探测器，也是像我们银河系一样的星系的直系祖先。他的研究技术将结合分析和数值理论，明确的重点是指导和解释当前和未来的观测。***

AST-0302148Santos, MichaelDr. Michael Santos will take his Mathematical and Physical Sciences Distinguished International Postdoctoral Research Fellowship to Cambridge University in the United Kingdom. He will study the properties of the first stars and galaxies to form in our universe, more than twelve billion years ago. These primordial precursors of our galaxy and Sun are key in understanding the subsequent assembly of luminous structure in our universe, but are difficult to observe directly. However, the young universe was in some ways a simpler place than what we see now, making it accessible to theoretical studies. His research will focus on many unexplored aspects of how the first galaxies interacted with each other and the universe around them. In particular, he will study the smallest galaxies, because these are both "canaries in the mineshaft," the most sensitive probes of early physical processes, and the direct ancestors of galaxies like our own Milky Way. His research techniques will incorporate analytic and numerical theory, with a clear focus on guiding and interpreting current and future observations. ***
