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…
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 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…
Simulations of gas inflow in the Milky Way I. Stellar-Feedback-Regulated Transport from the Central Molecular Zone to the Circumnuclear disk
Zi-Xuan Feng, Mattia C. Sormani, Robin G. Tress +18
We perform hydrodynamical simulations with radially varying resolution to study the effects of stellar feedback on the radial inflow of gas from the Central Molecular Zone (CMZ, $R…
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…
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…
