Abstract

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.
