Atoms and nuclei comprise ordinary matter---galaxies, mountains, people, DNA, etc. Inside the nuclei are protons and neutron, and, if we look still inward, we will encounter quarks in a frozen state. Physicists are trying to manipulate these quarks by aiming impressively high energy beams of atomic nuclei at one another. The kinetic energy is converted largely to heat in an attempt to melt the protons and neutrons and harvest the quarks, so to speak. Subnuclear particle properties make this difficult because they are so strongly interacting. However, during the production and persistence phases of this heated system, bursts of electromagnetic energy are emitted. Examining these bursts both theoretically and experimentally provides scientists with their best chances of ``seeing the inside of an impressively hot fireball''. This research proposal concerns models for computing the bursts of energy emitted electromagnetically from heavy ion reactions and also encompasses a research training effort through mentoring students for graduate school, science teaching, and industry. The students will be enriched through capstone experiences and will disseminate their scientific results and their impressions to the college of science and engineering, to the university and the regional community.

原子和原子核组成了普通的物质-星系、山脉、人、DNA等。原子核里面是质子和中子，如果我们向内看，我们会遇到处于冻结状态的夸克。 物理学家们正试图通过令人印象深刻的原子核高能束相互瞄准来操纵这些夸克。 动能大部分转化为热量，试图熔化质子和中子，从而获得夸克。亚核粒子的性质使这一点变得困难，因为它们的相互作用非常强。 然而，在这个加热系统的产生和持续阶段，电磁能量的爆发被发射出来。 从理论上和实验上研究这些爆发为科学家提供了“看到令人印象深刻的热火球内部”的最佳机会。 这项研究计划涉及计算重离子反应电磁发射的能量爆发的模型，还包括通过指导研究生院，科学教学和工业的学生进行研究培训。 学生将通过顶点经验丰富，并将传播他们的科学成果和他们的印象，科学和工程学院，大学和区域社区。
