摘要
星暴星系是一类内部正在发生极为剧烈恒星形成的天体。介绍了星暴星系的研究历史及星暴星系的定义。综述了从射电波段到Ｘ 射线波段星暴星系的光度和光谱观测特征及其研究的最新进展。列出了星暴星系研究中存在的一些热点问题， 包括星暴的触发机制、星暴时标、星族组分、恒星形成率、初始质量函数、内红化以及星暴星系与活动星系核之间的关系等。最后，
Starburst galaxies are those in which star formation occurs at a much higher rate than the mean rate in a typical galactic time-scale. In this review, the study history and the definition of starburst galaxies are introduced first. Then, we briefly summarize the photometric and spectral observation properties (from radio to X-ray), and the latest progress of starburst galaxies. We list several interesting problems in starburst galaxies study, including the trigger mechanisms, the star formation time-scale, the stellar population, the initial mass function (IMF), the interstellar reddening of starburst galaxies and the connection between starburst galaxies and active galaxy nuclei (AGN). Finally, some potential observation and theoretical methods to solve these problems are presented.
