Unveiling True Galaxy Abundance Evolution at z=6-15 with Precision Simulations and Analysis

该计划的目的是进行尖端的计算机模拟，以帮助理解年轻宇宙日益丰富的观测结果。这些模拟将研究第一批恒星的辉煌生命和爆炸性死亡所造成的损害。恒星之间的物质被强烈的高能辐射煮熟，模拟将研究这种烹饪的后果。暗物质的粒子，非辐射物质对引力的反应，所以暗物质可能影响第一批恒星和星系的形成。这些模拟将研究这种影响如何取决于对这些知之甚少的粒子的假设质量。将这些模拟与越来越多的对年轻宇宙的地面和空间观测结果进行比较，将大大加强从这些观测结果中得出的推论。新的模拟将在纽约市的美国自然历史博物馆的罗斯-海登天文馆的IMAX影院进行适当的可视化和向公众展示。该团队之前的视频每天都会在该场地播放，使其成为公众访问的有效点，尤其是对于年轻观众来说。

The aim of the proposal is to conduct cutting-edge computersimulations to help understand the increasingly rich observations ofthe young Universe. The simulations will study the damage wrought bythe brilliant life and explosive death of the first stars. Thematerial between the stars is cooked by intense, high-energy radiationand the simulations will study the consequences of thatcooking. Particles of dark, non-radiating matter respond to the forceof gravity, so dark matter could influence the formation of the firststars and galaxies. The simulations will study how this influencedepends on the mass assumed for these poorly-understood particles.Comparisons between the simulations and the growing body of ground-and space-based observations of the young Universe will significantlystrengthen the inferences drawn from those observations. The newsimulations will be suitably visualized and shown to the public in theIMAX theatre of the Rose-Hayden Planetarium of the American Museum ofNatural History in New York City. Prior videos from this team havebeen featured daily in that venue, making it an effective point ofpublic access especially for young viewers.
