ALMAGAL V. Relations between the core populations and the parent clump physical properties
D. Elia, A. Coletta, S. Molinari +54
Context. The fragmentation of massive molecular clumps into smaller, potentially star-forming cores plays a key role in the processes of high-mass star formation. The ALMAGAL proje…
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) coe…
ALMA-IMF. XXI.: NH kinematics in the G012.80 protocluster: Evidence for filament rotation and evolution
J. Salinas, A. M. Stutz, R. H. Álvarez-Gutiérrez +20
(abridged) We aim to characterize kinematic processes in the G012.80 protocluster. We principally focus on the NH(10) emission to trace the dense and cold gas. Additiona…
ALMA-IMF XX: Core fragmentation in the W51 high-mass star-forming region
T. Yoo, A. Ginsburg, J. Braine +27
We present a study of core fragmentation in the W51-E and W51-IRS2 protoclusters in the W51 high-mass star-forming region. The identification of core fragmentation is achieved by t…
The ALMA-QUARKS Survey: III. Clump-to-core fragmentation and search for high-mass starless cores
Dongting Yang, Hong-Li Liu, Tie Liu +43
The Querying Underlying mechanisms of massive star formation with ALMA-Resolved gas Kinematics and Structures (QUARKS) survey observed 139 infrared-bright (IR-bright) massive proto…
ALMASOP. A Rotating Feature Rich in Complex Organic Molecules in a Protostellar Core
Shih-Ying Hsu, Chin-Fei Lee, Doug Johnstone +25
Interstellar complex organic molecules (COMs) in solar-like young stellar objects (YSOs), particularly within protostellar disks, are of significant interest due to their potential…
ALMAGAL IV. Morphological comparison of molecular and thermal dust emission using the histogram of oriented gradients (HOG) method
C. Mininni, S. Molinari, J. D. Soler +46
The study of molecular line emission is crucial to unveil the kinematics and the physical conditions of gas in star-forming regions. Our aim is to quantify the reliability of using…
The ALMA-ATOMS survey: A sample of weak hot core candidates identified through line stacking
Zi-Yang Li, Xunchuan Liu, Tie Liu +33
Hot cores represent critical astrophysical environments for high-mass star formation, distinguished by their rich spectra of organic molecular emission lines. We aim to utilize hig…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -XXI. A Large-sample Observational Study of Ethanol and Dimethyl Ether in Hot Cores
Zhiping Kou, Xiaohu Li, Sheng-Li Qin +21
Hot cores, as a stage of massive star formation, exhibit abundant line emissions of COMs. We present a deep line survey of two isomers of CHO: ethanol (CHOH; EA), a…
Turbulent fragmentation as the primary driver of core formation in Polaris Flare and Lupus I
Kousuke Ishihara, Fumitaka Nakamura, Patricio Sanhueza +1
Stars form from dense cores in turbulent molecular clouds. According to the standard scenario of star formation, dense cores are created by cloud fragmentation. However, the physic…
