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…

Pei-Ying Hsieh, Daniel L. Walker, Adam Ginsburg +59
We present data from the ALMA Central Molecular Zone Exploration Survey (ACES) Large Program, which provides broad spectral-line and 3 mm continuum coverage of the Central Molecula…
ALMA Central Molecular Zone Exploration Survey (ACES)-IV. Data of the two intermediate-width spectral windows
Xing Lu, Daniel L. Walker, Adam Ginsburg +61
We release the intermediate-width spectral window data from the ALMA Central Molecular Zone Exploration Survey (ACES) Large Program, which covers SiO(2-1), SO(2_2-1_1), H13CO+(1-0)…
ALMA Central Molecular Zone Exploration Survey (ACES) I: Overview
Steven N. Longmore, John Bally, Ashley T. Barnes +95
The mass flows and energy cycles within the inner regions of galaxies exert a powerful influence on the evolution of the galaxy population. The centre of the Milky Way is the only…
ALMA Central molecular zone Exploration Survey (ACES) III: Molecular line data reduction and HNCO and HCO data
Daniel L. Walker, Adam Ginsburg, Ashley T. Barnes +64
The ALMA Central molecular zone Exploration Survey (ACES) large program has observed the inner ~ 200 pc of the Milky Way at 3 mm (Band 3) using ALMA's 12m, 7m, and Total Power arra…
ALMA Central Molecular Zone Exploration Survey (ACES) II: 3mm continuum images
Adam Ginsburg, Daniel L. Walker, Ashley T. Barnes +69
The ALMA Central Molecular Zone Exploration Survey, ACES, has mapped square arcminutes at 3 mm toward the center of our Galaxy. ACES provides the first large-scale, h…
A JWST NIRCam/MIRI view of the W51A high-mass star-forming region
Taehwa Yoo, Adam Ginsburg, Nazar Budaiev +10
We present observations of the W51A region, including the massive protoclusters W51-E and W51-IRS2, with JWST in 10 NIRCam and 5 MIRI filters. In this work, we highlight the most n…
The Colors of Ices: Measuring ice column density through photometry
Adam Ginsburg, Savannah R. Gramze, Matthew L. N. Ashby +8
Ices imprint strong absorption features in the near- and mid-infrared, but until recently they have been studied almost exclusively with spectroscopy toward small samples of bright…
ALMA-IMF XX: Core fragmentation in the W51 high-mass star-forming region
T. Yoo, A. Ginsburg, J. Braine +27
We present a study of core fragmentation in the W51-E and W51-IRS2 protoclusters in the W51 high-mass star-forming region. The identification of core fragmentation is achieved by t…
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…

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…
