The "Maggie" filament: Physical properties of a giant atomic cloud
J. Syed, J. D. Soler, H. Beuther +19
The atomic phase of the interstellar medium plays a key role in the formation process of molecular clouds. Due to the line-of-sight confusion in the Galactic plane that is associat…
Cold atomic gas identified by HI self-absorption. Cold atomic clouds toward giant molecular filaments
J. Syed, H. Beuther, P. F. Goldsmith +10
Stars form in the dense interiors of molecular clouds. The dynamics and physical properties of the atomic interstellar medium (ISM) set the conditions under which molecular clouds…
Fragmentation and kinematics in high-mass star formation: CORE-extension targeting two very young high-mass star-forming regions
H. Beuther, C. Gieser, S. Suri +24
Context: The formation of high-mass star-forming regions from their parental gas cloud and the subsequent fragmentation processes lie at the heart of star formation research. Aims:…
Clustered star formation at early evolutionary stages. Physical and chemical analysis of the young star-forming regions ISOSS J22478+6357 and ISOSS J23053+5953
C. Gieser, H. Beuther, D. Semenov +20
We aim to characterize the physical and chemical properties of fragmented cores during the earliest evolutionary stages in the very young star-forming regions ISOSS J22478+6357 and…
The history of dynamics and stellar feedback revealed by the HI filamentary structure in the disk of the Milky Way
J. D. Soler, H. Beuther, J. Syed +19
We present a study of the filamentary structure in the emission from the neutral atomic hydrogen (HI) at 21 cm across velocity channels in the 40'' and 1.5-km/s resolution position…
The filamentary structures in the CO emission toward the Milky Way disk
J. D. Soler, H. Beuther, J. Syed +11
We present a statistical study of the filamentary structure orientation in the CO emission observations obtained in the Milky Way Imaging Scroll Painting (MWISP) survey in the rang…
Atomic and molecular gas properties during cloud formation
J. Syed, Y. Wang, H. Beuther +15
Molecular clouds, which harbor the birthplaces of stars, form out of the atomic phase of the interstellar medium (ISM). We aim to characterize the atomic and molecular phases of th…
On the accuracy of HI observations in molecular clouds -- More cold HI than thought?
D. Seifried, H. Beuther, S. Walch +4
We present a study of the cold atomic hydrogen (HI) content of molecular clouds simulated within the SILCC-Zoom project. We produce synthetic observations of HI at 21 cm including…
Dynamical Accretion Flows -- ALMAGAL: Flows along filamentary structures in high-mass star-forming clusters
M. R. A. Wells, H. Beuther, S. Molinari +47
We use data from the ALMA Evolutionary Study of High Mass Protocluster Formation in the Galaxy (ALMAGAL) survey to study 100 ALMAGAL regions at 1 arsecond resolution located…
