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…
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 Origin of [CII] 158um Emission toward the HII Region Complex S235
L. D. Anderson, Z. Makai, M. Luisi +9
Although the 2P3/2-2P1/2 transition of [CII] at 158um is known to be an excellent tracer of active star formation, we still do not have a complete understanding of where within sta…
Clustering the Orion B giant molecular cloud based on its molecular emission
Emeric Bron, Chloé Daudon, Jérôme Pety +12
Previous attempts at segmenting molecular line maps of molecular clouds have focused on using position-position-velocity data cubes of a single line to separate the spatial compone…
Spatial distribution of star formation related to ionized regions throughout the inner Galactic plane
P. Palmeirim, A. Zavagno, D. Elia +35
We present a comprehensive statistical analysis of star-forming objects located in the vicinities of 1 360 bubble structures throughout the Galactic Plane and their local environme…
Dissecting the molecular structure of the Orion B cloud: Insight from Principal Component Analysis
Pierre Gratier, Emeric Bron, Maryvonne Gerin +12
Context. The combination of wideband receivers and spectrometers currently available in (sub-)millimeter observatories deliver wide- field hyperspectral imaging of the interstellar…
Turbulence and star formation efficiency in molecular clouds: solenoidal versus compressive motions in Orion B
Jan H. Orkisz, Jérôme Pety, Maryvonne Gerin +13
The nature of turbulence in molecular clouds is one of the key parameters that control star formation efficiency: compressive motions, as opposed to solenoidal motions, can trigger…
Feedback in Clouds II: UV Photoionisation and the first supernova in a massive cloud
Sam Geen, Patrick Hennebelle, Pascal Tremblin +1
Molecular cloud structure is regulated by stellar feedback in various forms. Two of the most important feedback processes are UV photoionisation and supernovae from massive stars.…
Globules and Pillars in Cygnus X I. Herschel Far-infrared imaging of the Cyg OB2 environment
N. Schneider, S. Bontemps, F. Motte +21
The radiative feedback of massive stars on molecular clouds creates pillars, globules and other features at the interface between the HII region and molecular cloud. We present her…
Understanding star formation in molecular clouds III. Probability distribution functions of molecular lines in Cygnus X
N. Schneider, S. Bontemps, F. Motte +11
Column density (N) PDFs serve as a powerful tool to characterize the physical processes that influence the structure of molecular clouds. Star-forming clouds can best be characteri…
Detection of two power-law tails in the probability distribution functions of massive GMCs
N. Schneider, S. Bontemps, P. Girichidis +20
We report the novel detection of complex high-column density tails in the probability distribution functions (PDFs) for three high-mass star-forming regions (CepOB3, MonR2, NGC6334…
Filaments in the Lupus molecular clouds
M. Benedettini, E. Schisano, S. Pezzuto +19
We have studied the filaments extracted from the column density maps of the nearby Lupus 1, 3, and 4 molecular clouds, derived from photometric maps observed with the Herschel sate…
Photoionisation Feedback in a Self-Gravitating, Magnetised, Turbulent Cloud
Sam Geen, Patrick Hennebelle, Pascal Tremblin +1
We present a new set of analytic models for the expansion of HII regions powered by UV photoionisation from massive stars and compare them to a new suite of radiative magnetohydrod…

N. Schneider, T. Csengeri, R. S. Klessen +6
We analyse column density and temperature maps derived from Herschel dust continuum observations of a sample of massive infrared dark clouds (G11.11-0.12, G18.82-0.28, G28.37+0.07,…
Understanding star formation in molecular clouds I. Effects of line-of-sight contamination on the column density structure
N. Schneider, V. Ossenkopf, T. Csengeri +6
Column-density maps of molecular clouds are one of the most important observables in the context of molecular cloud- and star-formation (SF) studies. With the Herschel satellite it…
Ionization compression impact on dense gas distribution and star formation, Probability density functions around H ii regions as seen by Herschel
P. Tremblin, N. Schneider, V. Minier +22
Ionization feedback should impact the probability distribution function (PDF) of the column density around the ionized gas. We aim to quantify this effect and discuss its potential…
