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.

理论研究将针对粒子物理学新思想的天体物理学意义进行。 人们认为早期宇宙具有巨大的密度和温度。 这些条件将提供比任何可以想象的实验室加速器更强大几个数量级的天然粒子加速器。 该研究将涉及研究新粒子（如果存在）对天体物理模型的影响。 将研究探测存在于我们银河系或河外环境中的宇宙弦（早期宇宙的残余物）的可能性。 该研究将集中于超导宇宙弦，它可以承载高达一百万亿电子伏的电流。 与几个实验小组的合作研究将集中于探测可能占我们银河系 90% 的“暗物质”的可能性。 我们将探讨这些粒子可能对太阳和其他恒星产生的影响。 这是总统青年研究员奖。
