Project AMIGA: The Inner Circumgalactic Medium of Andromeda from Thick Disk to Halo

The Astrophysical Journal
The inner circumgalactic medium (CGM) of galaxies, where disk and halo processes intersect, remains poorly characterized despite its critical role in regulating galaxy evolution.

The Molecular Clouds of M31

The Astrophysical Journal
Deep interferometric observations of CO and dust continuum emission are obtained with the Submillimeter Array at 230 GHz to investigate the physical nature of the giant molecular cloud (GMC) population in the Andromeda galaxy (M31).

The Role of Pressure in the Structure and Stability of GMCs in the Andromeda Galaxy

The Astrophysical Journal
We revisit the role of pressure in the structure, stability, and confinement of Giant Molecular Clouds (GMCs) in light of recently published observations and analysis of the GMCs in the Andromeda galaxy (M31). That analysis showed that, in the absence of

Bar-driven Gas Dynamics of M31

The Astrophysical Journal
The large-scale gaseous shocks in the bulge of M31 can be naturally explained by a rotating stellar bar. We use gas dynamical models to provide an independent measurement of the bar pattern speed in M31.
