Chemical Evolution of M31 [PDF]

, 2014
We review chemical evolution models developed for M31 as well as the abundance determinations available for this galaxy. Then we present a recent chemical evolution model for M31 including radial gas flows and galactic fountains along the disk, as well as a model for the bulge.

Extinction Distributions in Nearby Star-resolved Galaxies. I. M31

The Astronomical Journal
An extinction distribution of the Andromeda galaxy (M31) is constructed with member stars as tracers by fitting multiband photometric data from UKIRT/WFCAM, Panoramic Survey Telescope and Rapid Response System 1, and Gaia DR3.

Evaluation of the astrometric capability of Multi-Channel Imager and simulated calculation of proper motion of M31

Frontiers in Astronomy and Space Sciences
Introduction: The Multi-Channel Imager (MCI), one of the back-end modules of the future China Space Station Telescope (CSST), is designed for high-precision spacebased astronomical observations.

Deep Andromeda JCMT SCUBA-2 Observations. The Submillimeter Maps and Giant Molecular Clouds

The Astrophysical Journal Supplement Series
We have carried out unprecedentedly deep, nearly confusion-limited JCMT SCUBA-2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 μ m image with a ∼50 pc resolution yields a comprehensive catalog of 383 giant molecular clouds ...

Kinematics and Metallicity of the Dwarf Spheroidal Galaxy Andromeda XVIII

The Astrophysical Journal
Andromeda XVIII is an isolated dwarf galaxy 579 kpc away from the nearest large galaxy, M31. It is a candidate “backsplash galaxy” that might have been affected by a close passage to M31.

The nucleus of M31

The Astrophysical Journal, 1992
We calculate the broad-band spectrum expected of a 10 exp 7 solar mass black hole accreting from an ambient galactic wind in the nucleus of M31, and we discuss several testable predictions of this model: (1) when resolved, this source will probably be elongated, perhaps in the direction of the semistellar nucleus BD +40 148 deg; (2) its radio spectral ...
