Filamentary structures are ubiquitous in molecular clouds, and have been recently argued to play an important role in regulating the size and mass of embedded clumps through fragmentation and mass accretion. Here, we reveal the dynamical state and fragmentation of filamentary molecular gas associated with the Serpens South protocluster through analysis of wide (~4 x 4 pc) observations of NH3 (1,1) and (2,2) inversion transitions with the Green Bank Telescope. Detailed modeling of the NH3 lines… Expand
Morphology and Kinematics of Filaments in the Serpens and Perseus Molecular Clouds
We present H13CO+ (J=1-0) and HNC (J=1-0) maps of regions in Serpens South, Serpens Main and NGC 1333 containing filaments. We also observe the Serpens regions using H13CN (J=1-0). These dense gasExpand
Multicomponent Kinematics in a Massive Filamentary Infrared Dark Cloud
To probe the initial conditions for high-mass star and cluster formation, we investigate the properties of dense filaments within the infrared dark cloud G035.39-00.33 (IRDC G035.39) in a combinedExpand
Global hierarchical collapse in molecular clouds. Towards a comprehensive scenario
We present a unified description of the scenario of global hierarchical collapse (GHC). GHC constitutes a flow regime of (non-homologous) collapses within collapses, in which all scales accrete fromExpand
Fibers in the NGC 1333 proto-cluster
Are the initial conditions for clustered star formation the same as for non-clustered star formation? To investigate the initial gas properties in young proto-clusters we carried out a comprehensiveExpand
Temperature structure and kinematics of the IRDC G035.39–00.33
© ESO, 2017. Aims. Infrared dark clouds represent the earliest stages of high-mass star formation. Detailed observations of their physical conditions on all physical scales are required to improveExpand
Magnetized filamentary gas flows feeding the young embedded cluster in Serpens South
Observations indicate that molecular clouds are strongly magnetized, and that magnetic fields influence the formation of stars. A key observation supporting the conclusion that molecular clouds areExpand
Kinematics and star formation toward W33: a central hub as a hub–filament system
Aims. We investigate the gas kinematics and physical properties toward the W33 complex and its surrounding filaments. We study clump formation and star formation in a hub–filament system. Methods. WeExpand
Catalog of High Protostellar Surface Density Regions in Nearby Embedded Clusters
We analyze high-quality stellar catalogs for 24 young and nearby (within 1 kpc) embedded clusters and present a catalogue of 32 groups which have a high concentration of protostars. The medianExpand
Galactic cold cores IX. Column density structures and radiative transfer modelling
The Galactic Cold Cores (GCC) project has made Herschel observations of interstellar clouds where Planck detected compact sources of cold dust emission. Our aim is to characterise the structure ofExpand

Chains of dense cores in the Taurus L1495/B213 complex
(Abridged) We study the kinematics of the dense gas in the Taurus L1495/B213 filamentary region to investigate the mechanism of core formation. We use observations of N2H+(1-0) and C18O(2-1) carriedExpand
One puzzle in understanding how stars form in clusters is the source of mass—is all of the mass in place before the first stars are born, or is there an extended period when the cluster accretesExpand
Cores, filaments, and bundles: hierarchical core formation in the L1495/B213 Taurus region
Context. Core condensation is a critical step in the star-formation process, but it is still poorly characterized observationally. Aims. We have studied the 10 pc-long L1495/B213 complex in Taurus toExpand
The Dynamical State of the Serpens South Filamentary Infrared Dark Cloud
We present the results of N_2H^+ (J = 1-0) observations toward Serpens South, the nearest cluster-forming, infrared dark cloud. The physical quantities are derived by fitting the hyperfine structureExpand
Abundant Cyanopolyynes as a Probe of Infall in the Serpens South Cluster-Forming Region
We have detected bright HC7N J = 21 20 emission toward multiple locations in the Serpens South cluster-forming region using the K-Band Focal Plane Array at the Robert C. Byrd Green Bank Telescope.Expand
Line Profiles of Cores within Clusters. I. The Anatomy of a Filament
Observations are revealing the ubiquity of filamentary structures in molecular clouds. As cores are often embedded in filaments, it is important to understand how line profiles from such systemsExpand
Molecular Outflows from the Protocluster Serpens South
We present the results of CO (J = 3-2) and HCO+ (J = 4-3) mapping observations toward a nearby embedded cluster, Serpens South, using the ASTE 10 m telescope. Our CO (J = 3-2) map reveals that manyExpand
