The ALMA-QUARKS survey: Detection of two extremely dense substructures in a massive prestellar core
Xiaofeng Mai, Tie Liu, Xunchuan Liu +32
Only a handful of massive starless core candidates have been discovered so far, but none of them have been fully confirmed. Within the MM1 clump in the filamentary infrared dark cl…
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…
A survey of sulfur-bearing molecular lines toward the dense cores in eleven massive protoclusters
Mengyao Tang, Sheng-Li Qin, Tie Liu +6
Sulfur-bearing molecules are commonly detected in dense cores within star-forming regions, but the total sulfur budget is significantly low, when compared to the interstellar mediu…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -XXI. A Large-sample Observational Study of Ethanol and Dimethyl Ether in Hot Cores
Zhiping Kou, Xiaohu Li, Sheng-Li Qin +21
Hot cores, as a stage of massive star formation, exhibit abundant line emissions of COMs. We present a deep line survey of two isomers of CHO: ethanol (CHOH; EA), a…
ALMA Observations of Ethyl Formate toward Orion KL
Yaping Peng, V. M. Rivilla, Li Zhang +2
Orion KL is one of the prime templates of astrochemical and prebiotic chemical studies. We wish to explore more organic molecules with increasing complexity in this region. In part…
Formation of hub-filament structure triggered by cloud-cloud collision in W33 complex
Jian-Wen Zhou, Shanghuo Li, Hong-Li Liu +6
Hub-filament systems are suggested to be birth cradles of high-mass stars and clusters, but the formation of hub-filament structure is still unclear. Using the survey data FUGIN $^…
The ALMA-QUARKS Survey: Properties of Hot Molecular Fragments in the Massive Protocluster IRAS 17233-3606
Li Chen, Sheng-Li Qin, Dongting Yang +29
To investigate the physical mechanisms of fragmentation within the hot molecular core of the massive protocluster IRAS 17233-3606 (G351.78-0.54), we carried out a detailed analysis…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- XI. From inflow to infall in hub-filament systems
Jian-Wen Zhou, Tie Liu, Neal J. Evans +37
We investigate the presence of hub-filament systems in a large sample of 146 active proto-clusters, using HCO J=1-0 molecular line data obtained from the ATOMS survey.…
pUniFind: a unified large pre-trained deep learning model pushing the limit of mass spectra interpretation
Jiale Zhao, Pengzhi Mao, Kaifei Wang +12
Deep learning has advanced mass spectrometry data interpretation, yet most models remain feature extractors rather than unified scoring frameworks. We present pUniFind, the first l…
Sulfur-bearing molecules in Orion KL
Gan Luo, Siyi Feng, Di Li +5
We present an observational study of the sulfur (S)-bearing species towards Orion KL at 1.3 mm by combining ALMA and IRAM-30\,m single-dish data. At a linear resolution of 80…
Complex molecules in W51 North region
Jialei Rong, Sheng-Li Qin, Luis A. Zapata +6
We present Submillimeter Array (SMA) molecular line observations in two 2 GHz-wide bands centered at 217.5 and 227.5 GHz, toward the massive star forming region W51 North. We ident…
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…
Probing Star-Forming Properties via ALMA Observations of Massive Protocluster IRAS 15596-5301
Faxian Chang, Mengyao Tang, Tie Liu +8
To deepen our understanding of star-forming properties, we studied a massive protocluster IRAS 15596-5301 using ALMA 870 um and 3 mm data. High-resolution 870 um data reveal 34 den…
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…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- VIII. A search for hot cores by using CHCN, CHOCHO and CHOH lines
Sheng-Li Qin, Tie Liu, Xunchuan Liu +29
Hot cores characterized by rich lines of complex organic molecules are considered as ideal sites for investigating the physical and chemical environments of massive star formation.…
