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…
A New Cloud-Cloud Collision Source N68 toward the G35 Molecular Cloud Complex
En Chen, Xi Chen
Bubble N68 in the G35 complex shows clear cloud-cloud collision (CCC) signatures. Its semi-ring-like morphology harbors many significant massive star formation tracers: 6 HII regio…
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…
Radiative Compression of Dense Cores in the Pillars of Creation as Revealed by JWST Extinction Mapping
Jun Li, Bingqiu Chen, He Zhao +2
The Pillars of Creation in M16 represent an iconic star-forming region where stellar feedback shapes molecular cloud evolution. We present a detailed investigation of dust extincti…
A misaligned protostellar disk fed by gas streamers in a barred spiral-like massive dense core
Xiaofeng Mai, Tie Liu, Xunchuan Liu +42
High-mass stars, born in massive dense cores (MDCs), profoundly impact the cosmic ecosystem through feedback processes and metal enrichment, yet little is known about how MDCs asse…
Cooling process of the high-mass young stellar object G24.33+0.14 following an accretion burst
Xiaoyun Xu, Xi Chen, Yang Yang
The HMYSO G24.33+0.14 (G24), has recently been observed to undergo an accretion burst since September 2019, lasting approximately two years. By utilizing 1.3 mm observational data…
