Emergence of high-mass stars in complex fiber networks (EMERGE) VI. Turbulence dissipation and the formation of dense fibers
F. Bonanomi, A. Hacar, A. Socci +1
(Abridged) The turbulent cascade naturally generates a hierarchy of filaments within molecular clouds, with fibers suggested to be the first (tran-)sonic components formed out of i…
Low cosmic-ray ionisation at parsec scales in G035.39-00.33
Andrea Socci, Ashley Barnes, Jaime Pineda +11
Cosmic rays (CRs) regulate the chemical evolution of the gas and its coupling to the magnetic field in the densest and coldest regions of the interstellar medium (ISM). However, th…
Chemical Complexity in the Early Stages of Star Formation in the SKAO Era
Eleonora Bianchi, Mathilde Bouvier, Claudio Codella +44
About 350 molecules have been identified in the interstellar medium (ISM), including complex molecules relevant to prebiotic chemistry. A remarkable level of molecular diversity ha…
Kinematics of young stellar objects in NGC 2024 based on infrared proper motions
Alena Rottensteiner, Monika G. Petr-Gotzens, Stefan Meingast +6
The most recently formed young stellar objects (YSOs) in active star forming regions are excellent tracers of their parent cloud motion. Their positions and dynamics provide insigh…
Emergence of high-mass stars in complex fiber networks (EMERGE) V. From filaments to spheroids: the origin of the hub-filament systems
A. Hacar, R. Konietzka, D. Seifried +7
Identified as parsec-size, gas clumps at the junction of multiple filaments, hub-filament systems (HFS) play a crucial role during the formation of young clusters and high-mass sta…
