The ALMA-QUARKS Survey: Evidence of an Explosive Molecular Outflow in IRAS 15520--5234

Ariful Hoque, Tapas Baug, Estrella Guzman +25

We present a study of the massive protocluster IRAS 155205234, which displays evidence of an explosive molecular outflow that unleashed a kinetic energy of at least 10 er…

The ALMA-QUARKS Survey: Discovery of Dusty Fibrils inside Massive Star-forming Clumps

Yan-Kun Zhang, Tie Liu, Wenyu Jiao +35

We report the discovery of more than 323 superfine dusty filamentary structures (fibrils) inside 121 massive star forming clumps that are located in widely different Galactic envir…

The ALMA-QUARKS survey: Hot Molecular Cores are a long-standing phenomenon in the evolution of massive protostars

Dezhao Meng, Tie Liu, Jarken Esimbek +34

We present an analysis of the QUARKS survey sample, focusing on protoclusters where Hot Molecular Cores (HMCs, traced by CH3CN(12--11)) and UC HII regions (traced by H30α/H40α) c…

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…

Unraveling the Feedback-Regulated Star Formation Activities around the Expanding Galactic MIR Bubble [HKS2019] E71

Aayushi Verma, Saurabh Sharma, Lokesh K. Dewangan +8

We explore the physical environment of the Galactic mid-infrared (MIR) bubble [HKS2019] E71 (hereafter E71) through a multi-wavelength approach. E71 is located at the edge of a fil…
