The Role of Feedback in the Evolution of the First Galaxies

这个项目将探索早期星系中恒星形成的影响。这项研究将有助于我们理解第一批恒星和第一批星系中的超新星形成重元素以及它们返回星际介质的过程。当这样的大质量恒星形成时，它们会产生大量的电离辐射，然后在巨大的爆炸(超新星)中结束它们的生命。舒尔博士和他的合作者将使用超级计算机模拟，并结合对单个恒星的研究，探索所谓的星际介质中剩余气体的“恒星形成反馈”。他们还将探索从最早的恒星产生电离辐射和第一批重元素(形成行星、彗星甚至生命所需的元素)。

AST 0206042ShullThis project will explore the effects of star formation in early galaxies. This study will aid our understanding of the formation of the heavy elements and their return to the intergalactic medium by supernovae in the first stars and the first galaxies. When such massive stars form, they produce large amounts of ionizing radiation, before ending their lives in prodigious explosions (supernovae). Dr. Shull and his collaborators will use supercomputer simulations together with studies of individual stars to explore the so-called "feedback of star formation" on remaining gas in the intergalactic medium. They will also explore the production of ionizing radiation and the first heavy elements (needed for the formation of planets, comets, and even life) from the earliest stars.****
