On stellar migration from Andromeda to the Milky Way [PDF]

Recent Gaia observations suggest that some hypervelocity stars (HVSs) might originate from outside the Galaxy. We ask if these HVSs could come from as far as Andromeda. Therefore, we simulate HVSs originating in Andromeda with initial conditions based on

Probing ALP-Photon Oscillations with Fermi-LAT Observation of the Andromeda Galaxy

Universe
Axion-like particles (ALPs) can induce energy-dependent irregularities in gamma-ray spectra through ALP-photon oscillation in astrophysical magnetic fields.

The M31–M33 Interaction: Impact on M31’s Center-of-mass Motion and Satellite Orbits

The Astrophysical Journal
Inspired by recent studies of the interaction between the Milky Way and the Large Magellanic Cloud and its implications for the Milky Way’s global dynamical history, we investigate how the massive satellite galaxy M33 influences the position and velocity

The Fate of the Milky Way–Andromeda System: To Merge or Not?

The Astrophysical Journal Letters
It has long been predicted that the Milky Way (MW) will eventually merge with Andromeda (M31), a view reinforced by Hubble Space Telescope measurements indicating a small M31 transverse velocity. However, using updated Gaia-based proper motions (PMs) and

Spectral Transformations of Novae in Andromeda Galaxy [PDF]

, 2013
Nova outburst is the nuclear explosion on the surface of a white dwarf, which is caused by mass accretion from its companion star in the binary system.

Stellar Metallicities and Gradients in the Faint M31 Satellites Andromeda XVI and Andromeda XXVIII

The Astrophysical Journal
We present ∼300 stellar metallicity measurements in two faint M31 dwarf galaxies, Andromeda XVI ( M _V = −7.5) and Andromeda XXVIII ( M _V = –8.8), derived using metallicity-sensitive calcium H and K narrowband Hubble Space Telescope imaging.

Far-ultraviolet to Far-infrared Spectral Energy Distribution Modeling of the Star Formation History across M31

The Astronomical Journal
Our neighboring galaxy M31 has been recently surveyed at the far- and near-ultraviolet (FUV and NUV) with the UVIT telescope on AstroSat, which provides unprecedented sensitivity to young stellar populations.
