Theoretical research will be carried out on the astrophysical implications of new ideas in particle physics. The early universe is thought to have had enormous densities and temperatures. The conditions would provide a natural particle accelerator orders of magnitude more powerful than any conceivable laboratory accelerator. The research will involve looking into the effects of new particles, if they exist, on astrophysical models. Research on the possibility of detecting cosmic strings (trapped remnants of the early universe) existing in our galaxy or in extragalactic environments will be undertaken. The research will be focussed on superconducting cosmic strings, which can carry currents of up to one million billion electron volts. Collaborative research with several experimental groups will center on the possibility of detecting "dark matter" that may comprise 90% of our galaxy. The effects that these particles may have on our Sun and on other stars will be explored. This is a Presidential Young Investigator Award.

理论研究将基于粒子物理学中新思想的天体物理含义进行。 人们认为早期的宇宙具有巨大的密度和温度。 条件将提供比任何可能的实验室加速器更强大的天然粒子加速器阶数。 该研究将涉及研究新粒子对天体物理模型的影响。 将进行有关检测我们银河系或外层次环境中存在的宇宙弦（早期宇宙残留物）的可能性的研究。 这项研究将集中在超导宇宙弦上，宇宙弦可以携带高达1000亿电子电压的电流。 与几个实验组的合作研究将集中在检测可能占我们银河系90％的“暗物质”的可能性上。 这些颗粒可能对我们的太阳和其他恒星产生的影响。 这是一项总统年轻调查员奖。
