The First Water in the Universe

原始（或Pop III）超新星是宇宙中第一个伟大的核合成引擎，将后来形成行星和生命所需的第一批重元素驱逐到早期IGM中。借助恩佐自适应网格细化（AMR）代码的新功能，我们处于独特的位置，可以在红移z ~ 20的Pop III SN残留物中模拟宇宙中第一批水的形成。我们设想的项目是首先模拟单个SN爆炸中水的形成，然后演化出多个SN系统，研究它们如何聚集成恩佐的原始星系。最终的目标将是模拟原始星系中尘埃和水的积累，以研究第一颗行星形成的条件。

Primordial (or Pop III) supernovae were the first great nucleosynthetic engines of the universe,expelling the first heavy elements required for the later formation of planets and life into the early IGM.With new capabilities in the Enzo adaptive mesh refinement (AMR) code we are uniquely positionedto model the formation of the first water in the universe in Pop III SN remnants at redshifts z ~ 20.The Ph.D. project we envision is to first simulate the formation of water in individual SN explosionsand then later evolve multiple SN systems to study how they congregate into primitive galaxies inEnzo. The eventual goal will be to model the buildup of dust and water in primeval galaxies to studythe conditions of the formation of the first planets.
