Research Progress on Observations of Galactic Bars
摘要
Abstract
The galactic bar is a ubiquitous morphological structure in the nearby universe.There is an interaction between the bar and the host galaxy,which affects the physical properties of the host galaxy and drives secular evolution in the host galaxy.In recent years,many important progress on the evolutionary relationship between bars and galaxies have been made in observational studies.The research and identification methods of bars tend to be diversified,and the influence of bars on the evolution of galaxies and the physical mechanism are becoming more and more complete.Firstly,the influence of bars on the evolution of galaxies is introduced,and the emphasis is the effect of bars on the formation of stars in galaxies.Secondly,the distribution of bars in galaxies is analyzed,while the characteristics of barred spiral galaxies and the evolution of bars with red shift are described.Then,several main methods for identifying bars are summarized and discussed.Finally,the research on the relationship between bars and galaxies is summarized and prospected.关键词
