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…
The Isotopic and Elemental Abundances of Planet-Host Star TRAPPIST-1
Darío González Picos, Ian J. M. Crossfield, David Coria +6
Elemental and isotopic abundances are key tracers of planet formation, stellar evolution, and Galactic chemical evolution. Very low-mass stars are particularly interesting in this…
Unveiling the 3D structure of the central molecular zone from stellar kinematics and photometry: The 50 and 20 km/s clouds
Francisco Nogueras-Lara, Ashley T. Barnes, Jonathan D. Henshaw +25
The central molecular zone (CMZ), surrounding the Galactic centre, is the largest reservoir of dense molecular gas in the Galaxy. Despite its relative proximity, the 3D structure o…
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…
Tails of Gravity: Persistence of Star Formation in the CMZ Environment
Linjing Feng, Sihan Jiao, Fengwei Xu +16
We characterize star-forming gas in six molecular clouds (Sgr B1-off, Sgr B2, Sgr C, the 20 km s and 50 km s molecular clouds, and the Brick) in the Galactic central…
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…
JWST's first view of the most vigorously star-forming cloud in the Galactic center -- Sagittarius B2
Nazar Budaiev, Adam Ginsburg, Ashley T. Barnes +9
We report JWST NIRCAM and MIRI observations of Sgr B2, one of the most active sites of star formation in the Galaxy. These observations, using 14 filters spanning 1.5 to 25 microns…
Chemical templates of the Central Molecular Zone. Shock and protostellar object signatures under Galactic Center conditions
Katarzyna M. Dutkowska, Gijs Vermariën, Serena Viti +21
(Abridged) The Central Molecular Zone (CMZ) of the Milky Way exhibits extreme conditions, including high gas densities, elevated temperatures, enhanced cosmic-ray ionization rates,…
Dual-band Unified Exploration of Three CMZ Clouds (DUET). Cloud-wide census of continuum sources showing low spectral indices
Fengwei Xu, Xing Lu, Ke Wang +19
The Milky Way's Central Molecular Zone (CMZ) is measured to form stars 10 times less efficiently than in the Galactic disk, based on emission from high-mass stars. However, the CMZ…
Discovery of a Giant Molecular Cloud at the Midpoint of the Galactic Bar Dust Lanes: M4.7-0.8
Natalie Butterfield, Larry Morgan, Ashley Barnes +10
We present the detection of a previously unknown giant molecular cloud (GMC) located at the midpoint of the Galactic Bar Dust Lanes (M4.7--0.8), using spectral line observations ta…
Subclustering and Star Formation Efficiency in Three Protoclusters in the Central Molecular Zone

We present so far the highest resolution (0.04") ALMA 1.3 mm continuum observations of three massive star-forming clumps in the Central Molecular Zone, namely 20 km s…
ALMA observations of massive clouds in the central molecular zone: slim filaments tracing parsec-scale shocks
Kai Yang, Xing Lu, Yichen Zhang +22
The central molecular zone (CMZ) of our Galaxy exhibits widespread emission from SiO and various complex organic molecules (COMs), yet the exact origin of such emission is uncertai…
3-D CMZ II: Hierarchical Structure Analysis of the Central Molecular Zone
Cara Battersby, Daniel L. Walker, Ashley Barnes +16
The Central Molecular Zone (CMZ) is the way station at the heart of our Milky Way Galaxy, connecting gas flowing in from Galactic scales with the central nucleus. Key open question…
