Transferring Data from a Voronoi Mesh to an Adaptive Cartesian Grid in Pursuit of Self-consistent Top-down Star Formation
Sean C. Lewis, Brooke Polak, Mordecai-Mark Mac Low +5
Unstructured Voronoi mesh simulations offer many advantages for simulating self-gravitating gas dynamics on galactic scales. Adaptive mesh refinement (AMR) can be a powerful tool f…
Dense Molecular Ring-like structure in gaseous CO depletion region G34.74-0.12
Shuting Lin, Siyi Feng, Fengwei Xu +14
We report the discovery of a dense molecular ring-like structure in a dense (10 cm), cold (pc-scale CO depletion at a factor of 5), and young (10 year) star-forming…
Probing Turbulence, Gravity, Supernovae, and Magnetic Field Effects with the 6D Kinematics of Young Stars in Milky Way Star-Forming Regions
Benjamin N. Velguth, Yuan Li, Trung Ha +6
The dynamics of star forming gas can be affected by many physical processes, such as turbulence, gravity, supernova explosions, and magnetic fields. In this paper, we investigate s…
The ALMA Survey of 70 m Dark High-mass Clumps in Early Stages (ASHES). XII. Unanchored Forked Stream in the Propagating Path of a Protostellar Outflow
Shuting Lin, Siyi Feng, Patricio Sanhueza +14
Outflows are key indicators of ongoing star formation. We report the discovery of an unanchored forked stream within the propagating path of an extremely young protostellar outflow…
The THESAN project: environmental drivers of Local Group reionization
Yu Zhao, Aaron Smith, Rahul Kannan +5
The timing of cosmic reionization across Local Group (LG) analogues provides insights into their early histories and surrounding large-scale structure. Using the radiation-hydrodyn…
N-body simulations of galaxy bars generated by satellite collisions: effects of the impact geometry
Yufan Fane Zhou, Zhiyuan Li, Hui Li
Bars, a common and important structure in disk galaxies, can be induced by galaxy interactions. Although there have been some studies on bar formation in flybys or collisions, the…
