We examine the star-forming history of the M31 disk during the past few hundred Myr. The luminosity functions (LFs) of main-sequence stars at distances RGC > 21 kpc (i.e., >4 disk scale lengths) are matched by models that assume a constant star formation rate (SFR). However, at smaller RGC the LFs suggest that during the past ∼10 Myr the SFR was 2–3 times higher than during the preceding ∼100 Myr. The rings of cool gas that harbor a significant fraction of the current star-forming activity are…
A 2–3 billion year old major merger paradigm for the Andromeda galaxy and its outskirts
• Physics
• 2018
Recent observations of our neighbouring galaxy M31 have revealed that its disk was shaped by widespread events. The evidence for this includes the high dispersion ($V/\sigma$ $\le$ 3) of stars older
Signatures of the M31-M32 Galactic Collision
