This RUI award funds the research of Professor John T. Giblin, Jr. at Kenyon College.We live at a time when telescopes and gravitational wave-observatories are showering us with data. At the same time, there are still great unanswered questions about the nature of dark matter, dark energy, and the high-temperature initial moments of the Universe. As part of his research, Professor Giblin will probe high-energy physics using precision numerical simulations to predict the consequences of different models of high-energy physics. Professor Giblin will continue to develop, along with his undergraduate research students, cutting-edge computational tools to study the complex particle physics in the extreme environments of the early universe. This work is in the national interest as it builds foundational understanding of high-energy physics, trains scientifically literate human resources, and strengthens our understanding of numerical methods. Additionally, it will bring these important topics to high schools through outreach into physics classrooms.Specifically, Professor Giblin will study the detailed physics of (p)reheating at the end of inflation by studying realistic beyond-the-standard-model scenarios and implementing full non-linear gravitational simulations to better understand if cosmological processes can create primordial black holes. Professor Giblin will also study cosmological processes in the late universe to look at how nonlinear physics might contribute to our understanding of dark matter, the Hubble tension, and dark energy.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项RUI奖为肯尼恩学院的John T. Giblin教授的研究提供了资金。我们的生活在望远镜和引力浪潮守流员正在向我们涌入数据的时代。 同时，关于暗物质，暗能量和宇宙高温初始时刻的性质，仍然存在很大的未解决问题。 作为他的研究的一部分，吉布林教授将使用精确的数值模拟探测高能物理学，以预测不同高能量物理学模型的后果。 吉布林教授将继续与他的本科研究专业的学生一起发展尖端的计算工具，以研究早期宇宙极端环境中的复杂粒子物理。 这项工作符合国家的利益，因为它建立了对高能物理学，训练科学识字人力资源并加强我们对数值方法的理解的基本理解。 此外，它将通过宣传物理学课堂将这些重要主题带入高中。特别是，吉布林教授将通过研究通货膨胀结束时（P）重新加热的详细物理，通过研究现实的近距离模型场景并实施全面的非线性仿真，以更好地了解宇宙学过程是否可以创建原始的blacklacklyord blacksblack holles。 吉布林教授还将研究晚期宇宙中的宇宙学过程，以研究非线性物理学可能如何有助于我们对暗物质，哈勃张力和暗能量的理解。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估来通过评估来支持的。
