Dense Cores in the Vicinity of an HII Region
Ruofei Zhang, Xing Lu, Jingwen Wu +23
Massive stars strongly influence their surroundings through radiative and mechanical feedback, but its effects on dense gas structures at sub-pc scales remain poorly constrained. W…
ALOHA IRDCs Molecular Line Follow-up: I. Gas properties and kinematics
Jinjin Xie, Yaoting Yan, Zhiyuan Ren +109
Infrared Dark Clouds are ideal sites for investigating the initial conditions of massive star and cluster formation. The A Lei Of the Habitat and Assembly of Infrared Dark Clouds (…
Super-Jeans Fragmentation and Supply-Limited Accretion: Environment-Dependent Co-Evolution of Low- and High-Mass Cores
Dan Miao, Guang-Xing Li, Patricio Sanhueza
Protostellar core formation and growth in high-mass star-forming regions remain key to understanding massive star birth. We analyze the masses of 839 cores (resolved at scales of a…
The Keplerian disk, envelope, and streamers surrounding an early O-type protostar in the Sagittarius C cloud of the Central Molecular Zone
Jixiang Weng, Xing Lu, Yu Cheng +22
Disk-mediated accretion is central to theories of massive star formation, setting the initial conditions for their evolution. Yet observations of Keplerian disks around early O-typ…
Evolution of molecular clouds on galaxy-cloud scale revealed by gravitational network analysis : High-mass clouds may deplete nearby gas via accretion or merging
J. W. Zhou, Guang-Xing Li
Observations show that molecular gas in spiral galaxies is organized into a network of interconnected systems through the gravitational coupling of multi-scale hub-filament structu…
What role of gravity, turbulence and magnetic fields in high-mass star formation clouds?
An-Xu Luo, Hong-Li Liu, Guang-Xing Li +2
To explore the potential role of gravity, turbulence and magnetic fields in high-mass star formation in molecular clouds, this study revisits the velocity dispersion--size (--$L…
The ALMA-QUARKS Survey: II. the ACA 1.3 mm continuum source catalog and the assembly of dense gas in massive star-forming clumps
Fengwei Xu, Ke Wang, Tie Liu +30
Leveraging the high resolution, high sensitivity, and wide frequency coverage of the Atacama Large Millimeter/submillimeter Array (ALMA), the QUARKS survey, standing for "Querying…
Updated kinematics of the Radcliffe Wave: non-synchronous, dipole-like vertical oscillations
Zhi-Kai Zhu, Min Fang, Zu-Jia Lu +6
The kinematic information of the Radcliffe Wave (RW) is essential for determining its existence and gaining insights into its origin and evolution. In this work, we present an accu…
