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.

这一瑞奖资助了小约翰·T·吉卜林教授的研究。在凯尼恩学院，我们生活在一个望远镜和引力波观测站向我们提供大量数据的时代。与此同时，关于暗物质、暗能量的性质以及宇宙的高温初始时刻，仍有许多悬而未决的问题。作为他研究的一部分，吉布林教授将使用精确的数值模拟来探索高能物理，以预测不同高能物理模型的结果。Giblin教授将继续与他的本科生一起开发尖端计算工具，以研究早期宇宙极端环境中的复杂粒子物理。这项工作符合国家利益，因为它建立了对高能物理的基础理解，培养了具有科学素养的人力资源，并加强了我们对数值方法的理解。此外，它将通过扩展到物理课堂将这些重要的主题带到高中。具体地说，Giblin教授将通过研究现实的超出标准模型的场景和实施全面的非线性引力模拟来研究(P)在膨胀结束时重新加热的详细物理学，以更好地了解宇宙过程是否可以创造原始黑洞。吉柏林教授还将研究宇宙晚期的宇宙学过程，看看非线性物理如何有助于我们对暗物质、哈勃张力和暗能量的理解。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
