摘要

In a series of three papers published in The Astrophysical Journal, van der Marel and collaborators discuss the timing and dynamics of the 'imminent' - or at least inevitable - collision between the Milky Way and the neighbouring Andromeda galaxy. The inevitable aspect of this situation has been known for a long time. In 1959, Kahn and Woltjer estimated the mass of the Milky Way-Andromeda system through what has come to be called the 'timing argument', which invoked the assumption that the two galaxies would ultimately collide.
