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. ***

AST-0302148SANTOS，MICHAELDR。迈克尔·桑托斯（Michael Santos）将把他的数学和物理科学杰出国际博士后研究奖学金授予英国的剑桥大学。他将研究超过十二亿年前在我们宇宙中形成的第一批恒星和星系的特性。我们银河系和太阳的这些原始前体是理解随后的宇宙发光结构组装的关键，但很难直接观察到。 但是，在某些方面，年轻的宇宙比我们现在所看到的要简单，使理论研究可以访问。 他的研究将集中在许多未开发的方面，即第一个星系如何相互互动以及周围的宇宙。 特别是，他将研究最小的星系，因为这些星系都是“矿机中的金丝雀”，是早期物理过程的最敏感的探针，以及我们自己的银河系等星系的直接祖先。他的研究技术将融合分析和数值理论，明确着重于指导和解释当前和未来的观察结果。 ***
