Invited review talk SESSION 2 : Sizes, Masses, and Formation histories of the Milky Way and of Andromeda SESSION 2 : Sizes, Masses, and Formation histories of the Milky Way and of Andromeda

Description

Andromeda (M31) is the nearest giant spiral galaxy to the Milky Way and the most massive member of the Local Group. It has long been recognized that M31's mass measurement is essential to understand the formation and evolution of the Local Group. I will review the different observational and modelling techniques that have developed over time to measure the mass of M31. I will discuss the the best constraints today of the M31 mass and the consistency of that obtained from different techniques. I will also discuss possible improvements on the M31 mass measurement from improved techniques driven by data from forthcoming instruments and surveys.
