The proposed research covers the fields of Cosmic Ray Physics, Black Hole Physics and Cosmology. The arrival and detection at Earth of cosmic rays with energies above 1018 eV will afford researchers an outstanding opportunity to study high energy physics in a new regime. New detectors such as HiRes and Auger and OWL will allow one to study physics at ultra- high energy. The PI proposes to use cosmic ray data that will soon be available to see if TeV scale gravity is a viable theory. These extra dimensional theories lead to enhanced rates for quasi horizontal showers as well as predictions for black hole production at the LHC. If such effects are seen, the PI intends to extract information about the extra dimensions, as well as the Hawking temperature from the data. The degree of correlation of the cosmic ray directions with candidate sources will reveal information about the intergalactic magnetic field and thus constrain the physics of the early universe. The PI also intends to study whether recent observations of line shifts in the quasar absorption spectra are due to possible time variation of the fine structure constant a.

拟议的研究涵盖了宇宙射线物理，黑洞物理学和宇宙学的领域。在1018 eV以上的能量的宇宙射线的到达和检测将为研究人员提供一个在新制度中研究高能量物理学的绝佳机会。新的探测器，例如雇用，螺旋钻和猫头鹰将允许一个人以高能量研究物理。 PI建议使用宇宙射线数据，以查看TEV量表重力是否是可行的理论。 这些额外的维理论可提高准水平阵雨的速率以及LHC上黑洞产生的预测。如果看到这种影响，PI打算从数据中提取有关额外维度以及鹰温度的信息。宇宙射线方向与候选源的相关程度将揭示有关绘制磁场的信息，从而限制早期宇宙的物理。 PI还打算研究类星体吸收光谱中的线变位的最新观察结果是否是由于细胞结构常数a的可能时间变化引起的。
