Graham, James AST 96-17173 Dr. Graham will calibrate and apply infrared surface brightness fluctuation measurements of galaxies as a cosmological distance indicator. The observational part of the study will use a variety of telescopes to calibrate the method on nearby galaxies and then observe distances two to three times farther than before, as far as the Coma cluster. The theoretical portion of the research will use stellar population models to investigate the predicted behavior of infrared surface brightness fluctuations and to compare them with observations.

格雷厄姆（Graham），詹姆斯·阿斯特（James AST）96-17173格雷厄姆（Graham）博士将校准并将红外表面亮度波动的测量作为宇宙距离指标。 研究的观察部分将使用各种望远镜在附近的星系上校准该方法，然后观察到距离距离昏迷簇的距离是距离的两到三倍。 研究的理论部分将使用恒星种群模型来研究红外表面亮度波动的预测行为，并将其与观察结果进行比较。
