On volume density and star formation in nearby molecular clouds
Jan H. Orkisz, Jouni Kainulainen
Volume density is a key physical quantity controlling the evolution of the interstellar medium (ISM) and star formation, but it cannot be accessed directly by observations of molec…
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…
Deep learning denoising by dimension reduction: Application to the ORION-B line cubes
Lucas Einig, Jérôme Pety, Antoine Roueff +29
Context. The availability of large bandwidth receivers for millimeter radio telescopes allows the acquisition of position-position-frequency data cubes over a wide field of view an…
Gas kinematics around filamentary structures in the Orion B cloud
Mathilde Gaudel, Jan H. Orkisz, Maryvonne Gerin +27
Understanding the initial properties of star-forming material and how they affect the star formation process is key. From an observational point of view, the feedback from young hi…
Bird's eye view of molecular clouds in the Milky Way: II. Cloud kinematics from sub-pc to kpc scales
Andri Spilker, Jouni Kainulainen, Jan Orkisz
The kinematics of molecular gas are crucial for setting the stage for star formation. One key question related to the kinematic properties of gas is how they depend on the spatial…
3D shape explains star formation mystery of California and Orion A
Sara Rezaei Kh., Jouni Kainulainen
The new Gaia data release (EDR3) with improved astrometry has opened a new era in studying our Milky Way in fine detail. We use Gaia EDR3 astrometry together with 2MASS and WISE ph…
Initial Conditions for Star Formation: A Physical Description of the Filamentary ISM
A. Hacar, S Clark, F. Heitsch +4
The interstellar medium contains filamentary structure over a wide range of scales. Understanding the role of this structure, both as a conduit of gas across the scales and a diagn…
The width of Herschel filaments varies with distance
G. V. Panopoulou, S. E. Clark, A. Hacar +5
Context: Filamentary structures in nearby molecular clouds have been found to exhibit a characteristic width of 0.1 pc, as observed in dust emission. Understanding the origin of th…
Tracers of the ionization fraction in dense and translucent gas: I. Automated exploitation of massive astrochemical model grids
Emeric Bron, Evelyne Roueff, Maryvonne Gerin +21
The ionization fraction plays a key role in the physics and chemistry of the neutral interstellar medium, from controlling the coupling of the gas to the magnetic field to allowing…
C18O, 13CO, and 12CO abundances and excitation temperatures in the Orion B molecular cloud: An analysis of the precision achievable when modeling spectral line within the Local Thermodynamic Equilibrium approximation
Antoine Roueff, Maryvonne Gerin, Pierre Gratier +23
CO isotopologue transitions are routinely observed in molecular clouds to probe the column density of the gas, the elemental ratios of carbon and oxygen, and to trace the kinematic…
Dynamics of cluster-forming hub-filament systems: The case of the high-mass star-forming complex Monoceros R2
S. P. Trevino-Morales, A. Fuente, A. Sanchez-Monge +15
High-mass stars and star clusters commonly form within hub-filament systems. Monoceros R2, harbors one of the closest such systems, making it an excellent target for case studies.…
The stellar content of the infalling molecular clump G286.21+0.17
M. Andersen, P. J. Barnes, J. C. Tan +2
The early evolution during massive star cluster formation is still uncertain. Observing embedded clusters at their earliest stages of formation can provide insight into the spatial…
