- ALMA Observations of Massive Clouds in the Central Molecular Zone:
External-Pressure-Confined Dense Cores and Salpeter-like Core Mass Functions December 2, 2024We present Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 (1.3 mm) observations of dense cores in three massive molecular clouds within the Central Molecular Zone (CMZ) of the Milky Way, including the Dust Ridge cloud e, Sgr C, and the 20 km s-1 cloud, at a spatial resolution of 2000 au. Among the 834 cores […]Zhenying Zhang
- 3-D CMZ I: Central Molecular Zone Overview October 22, 2024The Central Molecular Zone (CMZ) is the largest reservoir of dense molecular gas in the Galaxy and is heavily obscured in the optical and near-IR. We present an overview of the far-IR dust continuum, where the molecular clouds are revealed, provided by Herschel in the inner 40\deg($|l| 10^{23}$ cm$^{-2}$) CMZ mass of M=$2\substack{+2 \\ -1} […]Cara Battersby
- 3-D CMZ II: Hierarchical Structure Analysis of the Central Molecular
Zone October 22, 2024The 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 questions remain about its 3-D structure, star formation properties, and role in regulating this gas inflow. In this work, we identify a hierarchy of discrete […]Cara Battersby
- 3-D CMZ IV: Distinguishing Near vs. Far Distances in the Galactic Center
Using Spitzer and Herschel October 22, 2024A comprehensive 3-D model of the central 300 pc of the Milky Way, the Central Molecular Zone (CMZ) is of fundamental importance in understanding energy cycles in galactic nuclei, since the 3-D structure influences the location and intensity of star formation, feedback, and black hole accretion. Current observational constraints are insufficient to distinguish between existing […]Dani Lipman
- 3-D CMZ III: Constraining the 3-D structure of the Central Molecular
Zone via molecular line emission and absorption October 22, 2024The Milky Way's Central Molecular Zone (CMZ) is the largest concentration of dense molecular gas in the Galaxy, the structure of which is shaped by the complex interplay between Galactic-scale dynamics and extreme physical conditions. Understanding the 3-D geometry of this gas is crucial as it determines the locations of star formation and subsequent feedback. […]Daniel L. Walker
- Disruption of a massive molecular cloud by a supernova in the Galactic
Centre: Initial results from the ACES project September 18, 2024The Milky Way's Central Molecular Zone (CMZ) differs dramatically from our local solar neighbourhood, both in the extreme interstellar medium conditions it exhibits (e.g. high gas, stellar, and feedback density) and in the strong dynamics at play (e.g. due to shear and gas influx along the bar). Consequently, it is likely that there are large-scale […]M. Nonhebel
- Dynamical Accretion Flows -- ALMAGAL: Flows along filamentary structures
in high-mass star-forming clusters August 15, 2024We use data from the ALMA Evolutionary Study of High Mass Protocluster Formation in the Galaxy (ALMAGAL) survey to study 100 ALMAGAL regions at $\sim$ 1 arsecond resolution located between $\sim$ 2 and 6 kpc distance. Using ALMAGAL $\sim$ 1.3mm line and continuum data we estimate flow rates onto individual cores. We focus specifically on […]M. R. A. Wells
- SOFIA/FORCAST Galactic Center Source Catalog July 10, 2024The central regions of the Milky Way constitute a unique laboratory for a wide swath of astrophysical studies, consequently the inner $\sim$400 pc has been the target of numerous large surveys at all accessible wavelengths. In this paper we present a catalog of sources at 25 and 37 $\mu$m located within all of the regions […]Angela S. Cotera

The PRIMA team is pleased to share the news that NASA has selected our concept for phase-A study. We are grateful for all the community effort that has brought us this far, and we are excited to continue to grow the PRIMA community going forward!
What what, ya girl got tenure! 🎉🎉🎉
Thanks so much everyone for the congratulations, wowzers! Feeling the love 💕 Long week but finally time to celebrate
I've been seeing a lot of great posters with amazing styles and sometimes art, but this one speaks to my heart...if Daria's on twitter can someone please RT and tag?
