This study continues Dr. Knapp's creative and respected studies of the intersterllar medium. Recent improvements in observationalsensitivity, leading to the detection of small amounts of cold gas and dust in elliptical galaxies, offer the opprotunity to study the interstellar medium in situations quite different from that in the galactic disk. These observations will be followed up by infrared dust studies, investigations of the fueling of nuclear activity, and studies of the vertical structure of atomic and molecular gas in the disk of our own galaxy.

这项研究延续了纳普博士对胸骨中间层的创造性和受人尊敬的研究。最近观测灵敏度的提高导致在椭圆星系中探测到少量的冷气体和尘埃，这为在与银盘完全不同的情况下研究星际介质提供了机会。在这些观测之后，将进行红外尘埃研究，研究核活动的燃料，以及研究我们银河系盘中原子和分子气体的垂直结构。
