CMZoom IV. Incipient High-Mass Star Formation Throughout the Central Molecular Zone
H Perry Hatchfield, Cara Battersby, Ashley T. Barnes +15
In this work, we constrain the star-forming properties of all possible sites of incipient high-mass star formation in the Milky Way's Galactic Center. We identify dense structures…
A probable Keplerian disk feeding an optically revealed massive young star
Anna F. McLeod, Pamela D. Klaassen, Megan Reiter +3
The canonical picture of star formation involves disk-mediated accretion, with Keplerian accretion disks and associated bipolar jets primarily observed in nearby, low-mass young st…
Star Formation Efficiency in Nearby Galaxies Revealed with a New CO-to-H2 Conversion Factor Prescription
Yu-Hsuan Teng, I-Da Chiang, Karin M. Sandstrom +24
Determining how galactic environment, especially the high gas densities and complex dynamics in bar-fed galaxy centers, alters the star formation efficiency (SFE) of molecular gas…
The JWST Galactic Center Survey -- A White Paper
Rainer Schoedel, Steve Longmore, Jonny Henshaw +111
The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…
JWST reveals widespread CO ice and gas absorption in the Galactic Center cloud G0.253+0.016
Adam Ginsburg, Ashley T. Barnes, Cara D. Battersby +7
We report JWST NIRCam observations of G0.253+0.016, the molecular cloud in the Central Molecular Zone known as The Brick, with the F182M, F187N, F212N, F410M, F405N, and F466N filt…
Deuterium Fractionation across the Infrared Dark Cloud G034.77-00.55 interacting with the Supernova Remnant W44
G. Cosentino, J. C. Tan, I. Jiménez-Serra +10
Supernova remnants (SNRs) may regulate star formation in galaxies. For example, SNR-driven shocks may form new molecular gas or compress pre-existing clouds and trigger the formati…
Fuelling the nuclear ring of NGC 1097
Mattia C. Sormani, Ashley T. Barnes, Jiayi Sun +24
Galactic bars can drive cold gas inflows towards the centres of galaxies. The gas transport happens primarily through the so-called bar ``dust lanes'', which connect the galactic d…
Kinematic analysis of the super-extended HI disk of the nearby spiral galaxy M83
Cosima Eibensteiner, Frank Bigiel, Adam K. Leroy +33
We present new HI observations of the nearby massive spiral galaxy M83, taken with the VLA at angular resolution ( pc) of an extended (1.5 deg…
Kinematics of Galactic Centre clouds shaped by shear-seeded solenoidal turbulence
Maya A. Petkova, J. M. Diederik Kruijssen, Jonathan D. Henshaw +17
The Central Molecular Zone (CMZ; the central ~ 500 pc of the Galaxy) is a kinematically unusual environment relative to the Galactic disc, with high velocity dispersions and a stee…
Mother of Dragons: A Massive, quiescent core in the dragon cloud (IRDC G028.37+00.07)
A. T. Barnes, J. Liu, Q. Zhang +15
Context: Core accretion models of massive star formation require the existence of massive, starless cores within molecular clouds. Yet, only a small number of candidates for such t…
Star Formation Laws and Efficiencies across 80 Nearby Galaxies
Jiayi Sun, Adam K. Leroy, Eve C. Ostriker +37
We measure empirical relationships between the local star formation rate (SFR) and properties of the star-forming molecular gas on 1.5 kpc scales across 80 nearby galaxies. These r…
The ALMOND Survey: Molecular cloud properties and gas density tracers across 25 nearby spiral galaxies with ALMA
Lukas Neumann, Molly J. Gallagher, Frank Bigiel +28
We use new HCN(1-0) data from the ALMOND (ACA Large-sample Mapping Of Nearby galaxies in Dense gas) survey to trace the kpc-scale molecular gas density structure and CO(2-1) data f…
CMZoom III: Spectral Line Data Release
Daniel Callanan, Steven N. Longmore, Cara Battersby +21
We present an overview and data release of the spectral line component of the SMA Large Program, \textit{CMZoom}. \textit{CMZoom} observed CO(2-1), CO(2-1) and C$^{18…
PHANGS-JWST First Results: Mid-infrared emission traces both gas column density and heating at 100 pc scales
Adam K. Leroy, Karin Sandstrom, Erik Rosolowsky +48
We compare mid-infrared (mid-IR), extinction-corrected H, and CO (2-1) emission at 70--160 pc resolution in the first four PHANGS-JWST targets. We report correlation strengths,…
PHANGS-JWST First Results: The Dust Filament Network of NGC 628 and its Relation to Star Formation Activity
David A. Thilker, Janice C. Lee, Sinan Deger +36
PHANGS-JWST mid-infrared (MIR) imaging of nearby spiral galaxies has revealed ubiquitous filaments of dust emission in intricate detail. We present a pilot study to systematically…
