Abstract

Conclusions. The high- and low -extinction PNe are associated with the young thin and old thicker disc of M 31, respectively, whose velocity dispersion values increase with age. These values are almost twice and three times that of the Milky Way disc stellar population of corresponding ages, respectively. From comparison with simulations of merging galaxies, we find that the age velocity dispersion relation in the M 31 disc measured using PNe is indicative of a single major merger that occurred 2.5-4.5 Gyr ago with an estimated merger mass ratio X1:5.
