The core population and kinematics of a massive clump at early stages: an ALMA view
E. Redaelli, S. Bovino, P. Sanhueza +5
High-mass star formation theories make distinct predictions on the properties of the prestellar seeds of high-mass stars. Observations of the early stages of high-mass star formati…
Properties of dense molecular gas along the major axis of M 82
Fei Li, Zhi-Yu Zhang, Junzhi Wang +6
Dense gas is important for galaxy evolution and star formation. Optically-thin dense-gas tracers, such as isotopologues of HCN, HCO+, etc., are very helpful to diagnose excitation…
The ALMA Survey of 70 μm Dark High-mass Clumps in Early Stages (ASHES). VI. The core-scale CO-depletion
Giovanni Sabatini, Stefano Bovino, Patricio Sanhueza +11
Studying the physical and chemical properties of cold and dense molecular clouds is crucial for the understanding of how stars form. Under the typical conditions of infrared dark c…

Jian-Wen Zhou, Tie Liu, Neal J. Evans +37
We investigate the presence of hub-filament systems in a large sample of 146 active proto-clusters, using HCO J=1-0 molecular line data obtained from the ATOMS survey.…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): How do dense core properties affect the multiplicity of protostars?
Qiuyi Luo, Tie Liu, Kenichi Tatematsu +34
During the transition phase from a prestellar to a protostellar cloud core, one or several protostars can form within a single gas core. The detailed physical processes of this tra…
