Evolution of starless cores in massive clumps seen by the ALMA ASHES and QUARKS surveys
Dongting Yang, Hong-li Liu, Sheng-li Qin +28
We present a systematic comparative analysis of 324 starless cores in early-phase infrared-dark clouds (IRDCs; ASHES survey) and evolved-phase infrared-bright clouds (IRBCs; QUARKS…
ATOMS-QUARKS survey: Inflow and infall in massive protocluster G318.049+00.086: Evidence of competitive accretion
Shivani Gupta, Tapas Baug, Archana Soam +17
We present a gas kinematic study of the massive protocluster G318.049+00.086. The protocluster is reported to contain 12 prestellar core candidates and 4 protostellar cores. Filame…
The ALMA-ATOMS survey: Methanol emission in a large sample of hot molecular cores
Jiahang Zou, Tie Liu, Sheng-Li Qin +26
Methanol (CHOH) is a key complex organic molecule (COM) in the interstellar medium, widely used as a tracer of dense gas and hot molecular cores (HMCs). Using high-resolution…
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…
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-ATOMS-QUARKS survey: Resolving a chemically rich massive protostellar outflow
Jia-Hang Zou, Tie Liu, Fengwei Xu +19
We present a comprehensive study on the physical and chemical structures of a chemically rich bipolar outflow in a high-mass star forming region IRAS 162724837 (SDC335), utilizi…
