ACES VIII: A Survey of Compact, High-Velocity Features Observed in CS(2-1)

Dani R. Lipman, Jakub Poznanski, Savannah R. Gramze +46

The extreme kinematics of the Milky Way's Central Molecular Zone (CMZ) are influenced by processes such as dynamical shearing, cloud collisions, and stellar feedback. These events…

ACES VII. Compact Continuum Source Catalog of the Central Molecular Zone

Jennifer Wallace, Cara Battersby, Nazar Budaiev +58

The Central Molecular Zone (CMZ) resides in the inner few hundred parsecs of our Galaxy, and despite being the largest reservoir of dense molecular gas in the Milky Way, it has a r…

Electron temperature and emission measure of HII regions in the central molecular zone (CMZ) from H40 αrecombination line and continuum emissions by ALMA CMZ Exploration Survey - ACES -

Yoshiaki Sofue, Steven N. Longmore, Daniel Walker +40

Star formation activity in the Central Molecular Zone (CMZ) directly manifests itself as radio continuum free-free emission (Bremsstrahlung) and radio recombination line emission f…

ALMA Central molecular zone Exploration Survey (ACES) VI: ALMA Large Program Reveals a Highly Filamentary Central Molecular Zone

Cara Battersby, Miriam G. Santa-Maria, Dani Lipman +44

The Central Molecular Zone (CMZ) of the Milky Way is the way station that primarily controls how much gas flows from the disk of the Galaxy towards the central nucleus. While this…

ACES: The Magnetic Field in Large Filaments in the Galactic Center

Dylan M. Paré, Zi-Xuan Feng, Yue Hu +33

The Galactic Center (GC) is an extreme region of the Milky Way that is host to a complex set of thermal and non-thermal structures. In particular, the GC contains high-density gas…

Mapping CO Ice in a Star-Forming Filament in the 3 kpc Arm with JWST

Savannah Gramze, Adam Ginsburg, Nazar Budaiev +14

CO gas emission is a fundamental tool for measuring column density, but in cold, dark clouds, much of the CO is locked away in ice. We present JWST results from observations of a s…
