Local constraints on alcohol--thioalcohol analogs in G35.2N
Xuefang Xu, Shanghuo Li, Qian Gou +6
The chemistry of sulfur-bearing complex organic molecules in dense star-forming environments remains uncertain, partly because the dominant sulfur reservoirs in dense gas and ices…
Molecule-dependent Abundance Behavior of Oxygen-bearing Complex Organics in High-Mass Star-Forming Regions: A Uniform 50-source Survey
Xuefang Xu, Mingwei He, Qian Gou +10
We present a uniform IRAM-30\,m survey analysis of four oxygen-bearing complex organic molecules (COMs), methanol (CHOH), acetaldehyde (CHCHO), methyl formate (CHOCHO),…
First Interstellar Detection of Methyl Carbamate: A New Observational Anchor for Glycine Chemistry
Chunguo Duan, Fengwei Xu, Jun Kang +5
Glycine-the simplest amino acid-has remained undetected in the interstellar medium despite decades of sensitive searches, motivating alternative approaches to constrain its astroch…
Tentative Detection of the Glycine Isomer Glycolamide in Hot Molecular Core
Chunguo Duan, Fengwei Xu, Qian Gou +6
Understanding whether prebiotic molecules can endure and reform through the energetic stages of star formation is essential for tracing the continuity of interstellar chemistry tow…
The ALMA-QUARKS survey: Extensive detection of acetamide in multiple high-mass star-forming regions
Chunguo Duan, Xuefang Xu, Qian Gou +8
Acetamide (CHCONH), a key interstellar amide and a methyl derivative of formamide (NHCHO), has been sparsely detected, limiting insights into its prebiotic releva…
An ALMA Study of Molecular Complexity in the Hot Core G336.99-00.03 MM1
Chunguo Duan, Qian Gou, Tie Liu +9
High-mass star formation involves complex processes, with the hot core phase playing a crucial role in chemical enrichment and the formation of complex organic molecules. However,…
3 mm Spectroscopic Observations of Massive Star-Forming Regions with IRAM 30-m
Xuefang Xu, Junzhi Wang, Qian Gou +6
Broadband spectroscopic observations with high sensitivity provide an unbiased way to detect emissions of molecules in space. We present deep observations from ~ 105.8 GHz to 113.6…
The Milky Way atlas for linear filaments II. clump rotation versus filament orientation
Xuefang Xu, Ke Wang, Qian Gou +4
Dense clumps distributed along filaments are the immediate medium for star formation. Kinematic properties of the clumps, such as velocity gradient and angular momentum, combined w…
Convergent Filaments Contracting Towards an Intermediate-mass Prestellar Core
Zhiyuan Ren, Lei Zhu, Hui Shi +11
Filamentary structures are closely associated with star-forming cores, but their detailed physical connections are still not clear. We studied the dense gas in the region of OMC-3…
Filament Intersections and Cold Dense Cores in Orion A North
Chao Zhang, Zhiyuan Ren, Jingwen Wu +13
We studied the filament structures and dense cores in OMC-2,3 region in Orion A North molecular cloud using the high-resolution N2H+ (1-0) spectral cube observed with the Atacama L…
Independent Core Rotation in Massive Filaments in Orion
Xuefang Xu, Di Li, Y. Sophia Dai +2
We present high-angular-resolution ALMA (Atacama Large Millimeter Array) images of NH (1--0) that has been combined with those from the Nobeyama telescope toward OMC-2…
