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…
Effects of low resolution on the column density PDF of molecular clouds
Yuping Tang, Q. Daniel Wang, Grant W. Wilson +2
Observational resolution significantly impacts the interpretation of column density probability distribution functions (N-PDFs) in molecular clouds, which are essential for underst…
ALMA Polarization Study of the Magnetic Fields in Two Massive Clumps in the 20 km s Cloud of the Central Molecular Zone
Yuhua Liu, Xing Lu, Junhao Liu +14
We present the Atacama Large Millimeter/submillimeter Array (ALMA) observations of linearly polarized 870 m continuum emission at a resolution of 0.2 (200…
Detection of an Explosive Outflow in G34.26+0.15
Namitha Issac, Xing Lu, Tie Liu +6
This paper reports on the detection of a likely explosive outflow in the high-mass star-forming complex G34.26+0.15, adding to the small number (six) of explosive outflows detected…
The JCMT BISTRO Survey: Magnetic Fields Align with Orbital Structure in the Galactic Center
Janik Karoly, Derek Ward-Thompson, Kate Pattle +29
We present the magnetic field in the dense material of the Central Molecular Zone (CMZ) of the Milky Way, traced in 850 m polarized dust emission as part of the James Clerk Maxw…
The JCMT BISTRO Survey: The Magnetic Fields of the IC 348 Star-forming Region
Youngwoo Choi, Woojin Kwon, Kate Pattle +150
We present 850 m polarization observations of the IC 348 star-forming region in the Perseus molecular cloud as part of the B-fields In STar-forming Region Observation (BISTRO) s…
Super-Jeans fragmentation in massive star-forming regions revealed by triangulation analysis
Guang-Xing Li, Mengke Zhao, Xing Lu
Understanding the fragmentation of the gas cloud and the formation of massive stars remains one of the most challenging questions of modern astrophysical research. Either the gas f…
Magnetic Fields in Massive Star-forming Regions (MagMaR) IV: Tracing the Magnetic Fields in the O-type protostellar system IRAS 165474247
Luis A. Zapata, Manuel Fernández-López, Patricio Sanhueza +24
The formation of the massive stars, and in particular, the role that the magnetic fields play in their early evolutionary phase is still far from being completely understood. Here,…
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…
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…
Tentative detection of cyanoformamide NCCONH2 in space
Juan Li, Donghui Quan, Junzhi Wang +12
The peptide-like molecules, cyanoformamide (NCCONH2), is the cyano (CN) derivative of formamide (NH2CHO). It is known to play a role in the synthesis of nucleic acid precursors und…
