Walterbos, Rene 96-17014 Dr. Walterbos will study the shell structure in galactic disks and their relation to the overall structure of the interstellar medium in these galaxies. A key part of the study is to identify shells using an algorithm which they have developed and which has had demonstrated success. By quantifying the numbers and properties of expanding shells in different galaxies the researchers will study how the interstellar medium morphology may correlate with the local star formation rate and under what conditions expanding shells break out of the gas disk, allowing hot gas to escape into the halo of the galaxies.

沃尔特沃斯博士将研究星系盘中的壳层结构，以及它们与这些星系中星际介质的整体结构的关系。这项研究的一个关键部分是使用他们开发的并已证明成功的算法来识别炮弹。通过量化不同星系中膨胀壳的数量和性质，研究人员将研究星际介质形态如何与当地恒星形成速度相关，以及在什么条件下膨胀壳从气盘中爆发，允许热气体逃逸到星系的光晕中。
