星系团中盘状星系的冲压压力剥离

Ram pressure stripping of disk galaxies in galaxy clusters

E. Roediger

摘要:

当星系在主星系团的团内介质中移动时,它们会经历一个冲压压力,该压力至少会带走它们星际介质的很大一部分。这种冲压压力剥离似乎是特别重要的螺旋星系:这种情况是一个很好的候选人来解释星系团之间的差异,在附近的宇宙螺旋和他们的外地同行。因此,在过去的十年中,星系团中盘星系的冲压压力剥离一直是研究的重点。我回顾了在这一领域取得的进展,集中在理论工作,但不断比较观察。

英文摘要:

While galaxies move through the intracluster medium of their host cluster, they experience a ram pressure which removes at least a significant part of their interstellar medium. This ram pressure stripping appears to be especially important for spiral galaxies: this scenario is a good candidate to explain the differences observed between cluster spirals in the nearby universe and their field counterparts. Thus, ram pressure stripping of disk galaxies in clusters has been studied intensively during the last decade. I review advances made in this area, concentrating on theoretical work, but continuously comparing to observations.
