ALMA-QUARKS: Few-Thousand-Year Hatching out of "Egg": The Supersonic Breakout of a Hypercompact H II Region from Its Parental Hot Core
Siju Zhang, Guido Garay, Fengwei Xu +19
The kinematic evolution of hypercompact H II (HC H II) regions around young high-mass stars remains poorly understood due to complex interactions with parental environs. We present…
Discovery of a rich population of compact hub-filament systems in a single star-forming complex
L. K. Dewangan, Ram K. Yadav, Saurabh Sharma +4
We report the discovery of 45 compact hub-filament systems (HFSs; median size 2.4 pc) in infrared-dark clouds (IRDCs) in the W33 complex, located at the junction of the Scutu…
The ALMA-QUARKS survey: Evidence of a candidate high-mass prestellar core aside a bright-rimmed cloud IRAS 18290-0924
Dongting Yang, Hong-Li Liu, Shengli Qin +32
Although frequently reported in observations, the definitive confirmation of high-mass prestellar cores has remained elusive, presenting a persistent challenge in star formation st…
The ALMA-QUARKS survey: Hot Molecular Cores are a long-standing phenomenon in the evolution of massive protostars
Dezhao Meng, Tie Liu, Jarken Esimbek +34
We present an analysis of the QUARKS survey sample, focusing on protoclusters where Hot Molecular Cores (HMCs, traced by CH3CN(12--11)) and UC HII regions (traced by H30α/H40α) coe…
The ALMA-QUARKS Survey: III. Clump-to-core fragmentation and search for high-mass starless cores
Dongting Yang, Hong-Li Liu, Tie Liu +43
The Querying Underlying mechanisms of massive star formation with ALMA-Resolved gas Kinematics and Structures (QUARKS) survey observed 139 infrared-bright (IR-bright) massive proto…
An S-shaped filament formed due to Cloud-Cloud Collision in molecular cloud G178.28-00.61
Tianwei Zhang, Tie Liu, Yuefang Wu +18
We present compelling observational evidence supporting G178.28-00.61 as an early-stage candidate for Cloud-Cloud Collision (CCC), with indications of the formation of an S-shaped…
The ALMA-ATOMS Survey: Exploring Protostellar Outflows in HCN
Ariful Hoque, Tapas Baug, Lokesh K. Dewangan +25
We present the first systematic study of bipolar outflows using HCN as a tracer in a sample of 146 massive star-forming regions from ALMA-ATOMS survey. Protostellar outflows ar…
The ALMA-ATOMS survey: A sample of weak hot core candidates identified through line stacking
Zi-Yang Li, Xunchuan Liu, Tie Liu +33
Hot cores represent critical astrophysical environments for high-mass star formation, distinguished by their rich spectra of organic molecular emission lines. We aim to utilize hig…
Network of velocity-coherent filaments formed by supersonic turbulence in a very-high-velocity HI cloud
Xunchuan Liu, Tie Liu, Pak-Shing Li +17
The warm neutral medium (WNM) was thought to be subsonically/transonically turbulent, and it lacks a network of intertwined filaments that are commonly seen in both molecular cloud…
The ALMA-ATOMS survey: Vibrationally excited HCN lines in hot cores
Li Chen, Sheng-Li Qin, Tie Liu +26
Interstellar molecules are excellent tools for studying the physical and chemical environments of massive star-forming regions. In particular, vibrationally excited HCN (HC…
