Modelling Integrated Spectra of Globular Clusters and Elliptical Galaxies

该奖项支持的研究领域是球状星团和椭圆星系中的恒星群。马里兰大学的罗杰·贝尔博士和迈克尔·特里皮科博士将继续致力于球状星团和星系的综合光谱的生成。所使用的方法是独特的，因为贝尔和特里皮科博士根据合成的恒星光谱、理论等时线和质量函数建立了积分光谱，并以观测到的星系团颜色-星等图和光度函数为指导。在测试案例中，模型和观察之间的一致性非常令人鼓舞，但改进是有计划的。

The field of research supported by this award is that of stellar populations in globular clusters and elliptical galaxies. Dr. Roger Bell and Dr. Michael Tripicco at the University of Maryland will continue to work on the generation of integrated spectra of globular clusters and galaxies. The method used is unique in that Drs. Bell and Tripicco build the integrated spectra from synthetic stellar spectra, theoretical isochrones, and mass functions, and they are guided by observed cluster color-magnitude diagrams and luminosity functions. In test cases, the agreement between the model and observation is extremely encouraging, but improvements are planned.
