What major event often triggers the rapid consumption of gas that results in a quiescent elliptical galaxy following a merger of two spirals?
Answer
A starburst
When two spiral galaxies collide, the violent gravitational interactions often trigger a rapid, massive burst of new star formation, known as a starburst, which quickly consumes the remaining available gas.
