Multi-scale Gas Structure and Dynamics in an Extragalactic Central Molecular Zone
Liam M. Wang, Jiayi Sun, Yu-Hsuan Teng +4
The structures and dynamics of the interstellar medium are governed by a combination of self-gravity, external gravity, and various sources of ordered and random motions on differe…
The Radial and Vertical Structure of Molecular Gas in the Edge-On Galaxy NGC 4565
Grace Krahm, Adam K. Leroy, Jiayi Sun +11
We present high-resolution (0.94" 55 pc) ALMA CO(2-1) and 13CO(2-1) observations of the highly inclined (i~87.5 deg) galaxy NGC 4565 covering out to galactocentric radius…
The Structure of Molecular Gas in PHANGS-ALMA Galaxies: Cloud Spacing, Two-Point Correlation and Stacked Intensity Profiles
Hao He, Adam Leroy, Erik Rosolowsky +21
The sub-kpc scale gas structure encodes key information of giant molecular cloud (GMC) formation. Therefore, we aim for a quantitative description of molecular gas structure across…
Filamentary Hierarchies and Superbubbles II: Impact of superbubbles and galactic dynamics on filament formation and fragmentation
Rachel Pillsworth, Ralph E. Pudritz, Eric W. Koch +1
Large scale phenomena in spiral galaxies such as shear, supernovae, and magnetic fields all contribute to the formation and subsequent evolution of filamentary structure and star f…
Spatially-resolved interstellar dust properties in the face-on spiral galaxy M 99 as observed by NIKA2
L. Pantoni, F. Galliano, S. C. Madden +62
Large dust grains in thermal equilibrium dominate the far-infrared and contribute to the millimetre continuum of star-forming galaxies, but constraining their properties is difficu…
The Timescales of Embedded Star Formation as Observed in STARFORGE
Tobin M. Wainer, Julianne J. Dalcanton, Michael Y. Grudić +7
Star formation occurs within dusty molecular clouds that are then disrupted by stellar feedback. However, the timing and physical mechanisms that govern the transition from deeply…
