Could M31 be the result of a major merger?
EPJ Web of Conferences, 2012 We investigated a scenario in which M31 could be the remnant of a gas-rich major merger. Galaxy merger simulations, highly constrained by observations, were run using GADGET 2 in order to reproduce M31. We succeeded in reproducing the global shape of M31,

Keck Studies of M31's Stellar Halo [PDF]
, 2000 We present Keck 10-meter/LRIS spectra of candidate red giants in the halo of M31, located at a projected radius of R=19kpc on the minor axis. These spectroscopic targets have been selected using a combination of UBRI-based and morphological screening to ...

AstroSat UVIT Survey of M31: New Compact Source Catalog [PDF]
The Astrophysical Journal Supplement SeriesAn ultraviolet survey of M31 was carried out during 2017–2023 with the UltraViolet Imaging Telescope (UVIT) instrument on board the AstroSat Observatory. Here we present far- and near-ultraviolet (FUV and NUV) observations from the M31 UVIT survey, which

Revisiting the Role of M31 in the Dynamical History of the Magellanic Clouds [PDF]
, 2009 We study the dynamics of the Magellanic Clouds in a model for the Local Group whose mass is constrained using the timing argument/two-body limit of the action principle.

Probability distribution functions of gas in M31 and M51
Monthly Notices of the Royal Astronomical Society, 2015 We present probability distribution functions (PDFs) of the surface densities of ionized and neutral gas in the nearby spiral galaxies M31 and M51, as well as of dust emission and extinction Av in M31. The PDFs are close to lognormal and those for HI and

Evidence for a Massive Andromeda Galaxy Using Satellite Galaxy Proper Motions
The Astrophysical Journal, 2023 We present new mass estimates for Andromeda (M31) using the orbital angular momenta of four satellite galaxies (M33, NGC 185, NGC 147, and IC 10) derived from existing proper motions, distances, and line-of-sight velocities. We infer two masses for M31: $
