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)…
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…
Cloud-cloud collision and star formation in G013.313+0.193
Dilda Berdikhan, Jarken Esimbek, Christian Henkel +18
We study the G013.313+0.193 G013.313 region, a complex environment characterized by molecular cloud interactions indicative of cloud-cloud collision (CCC). Observations of the NH3(…
Evidence for Core-Core Collision in Barnard 68
Dalei Li, Christian Henkel, Alexander Kraus +10
The prestellar core Barnard 68 (B68) is a prototypical source to study the initial conditions and chemical processes of star formation. A previous numerical simulation suggested th…
