The TOP-SCOPE Survey of Planck Galactic Cold Clumps: Molecular gas properties
Yuebin Yang, Jarken Esimbek, Tie Liu +11
We surveyed 2008 Planck Galactic Cold Clumps (PGCCs) in and --0 lines using the Taeduk Radio Astronomy Observatory (TRAO) 14 m telescope'…
A 1.3 cm spectral line study of the W33 region
Kadirya Tursun, Christian Henkel, Jarken Esimbek +14
At a distance of 2.4kpc, W33 is one of the most prolific sources of molecular line emission, and it is an excellent research target for a centimeter spectral line search. We carrie…
The ALMA-QUARKS survey: Investigating Thermal Feedback of Massive Protostars in Hot Molecular Cores
Dezhao Meng, Tie Liu, Jarken Esimbek +33
We identify a sample of 83 spatially resolved hot molecular cores (HMCs) in the QUARKS survey, aiming at investigating thermal feedback from massive stars. Using CHCN\,(12--11)…
ALMA-QUARKS view of W49N: Multipolar episodic outflow associated with the most energetic Galactic water maser
Yunfan Jiao, Tie Liu, Wenyu Jiao +28
We present a detailed investigation of a multipolar episodic molecular outflow in the mini-starburst region W49N, which hosts the most luminous water maser in the Galaxy. Using hig…
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: Evidence of a candidate high-mass prestellar core aside a bright-rimmed cloud IRAS 18290-0924
Dongting Yang, Hong-Li Liu, Shengli Qin +32
Although frequently reported in observations, the definitive confirmation of high-mass prestellar cores has remained elusive, presenting a persistent challenge in star formation st…
