B)a very large luminosity compared to the total luminosity of the Milky Way.
C)strong radio emission from "lobes" of material well outside the visible boundaries of the galaxy.

Question

Quizplus · Accepted Answer

The distinguishing feature of a starburst galaxy is a very high rate of star formation, which can be 100 or more times greater than that in the Milky Way. This results in a large number of young and massive stars, as well as intense radiation and high-energy processes. While some starburst galaxies may exhibit other features, such as radio emission or X-ray bursters, these are not necessarily unique to this type of galaxy.
