摘要

摘要我们研究了NGC3351、NGC5055和NGC5457星系中恒星形成复合体（SFCs）的星际介质参数。这项研究结束了我们之前对许多螺旋星系中气体和尘埃的研究。这三个星系的数据证实了以下几点。河外SFCs的近红外和远红外亮度之间存在着紧密的相关性。8μm的排放量也与一氧化碳排放量有很强的相关性。原子和分子气体质量与相应的速度散射没有显示出任何强相关性；然而，在NGC 5055中，我们看到了SFC的暗示，其最大的速度散射位于星系外围。

Dust and gas in star-forming complexes in NGC 3351, NGC 5055, and NGC 5457

Abstract We present a study of the interstellar medium parameters in star-forming complexes (SFCs) in NGC 3351, NGC 5055, and NGC 5457 galaxies. This study concludes our previous investigations of gas and dust in a number of spiral galaxies. The data for the three galaxies confirm the following. There is a tight correlation between near-infrared and far-infrared luminosities of the extragalactic SFCs. Emission at 8 μm also shows a strong correlation with the carbon monoxide emission. Atomic and molecular gas masses do not show any strong correlation with the corresponding velocity scatters; however, in NGC 5055, we see a hint of the SFC with the largest velocity scatter being located at the galaxy periphery.
