Mon R2: A Hub-Filament System with an Infrared Bubble at the Hub center
L. K. Dewangan, N. K. Bhadari, A. K. Maity +3
A multi-wavelength, multi-scale study of the Mon R2 hub-filament system (HFS) reveals a spiral structure, with the central hub containing more mass than its filaments. ALMA C$^{18}…
G321.93-0.01: A Rare Site of Multiple Hub-Filament Systems with Evidence of Collision and Merging of Filaments
A. K. Maity, L. K. Dewangan, N. K. Bhadari +5
Hub-filament systems (HFSs) are potential sites of massive star formation (MSF). To understand the role of filaments in MSF and the origin of HFSs, we conducted a multi-scale and m…
Cloud-Cloud Collision: Formation of Hub-Filament Systems and Associated Gas Kinematics; Mass-collecting cone: A new signature of Cloud-Cloud Collision
A. K. Maity, T. Inoue, Y. Fukui +6
Massive star-forming regions (MSFRs) are commonly associated with hub-filament systems (HFSs) and sites of cloud-cloud collision (CCC). Recent observational studies of some MSFRs s…
Direct observational evidence of multi-epoch massive star formation in G24.47+0.49
Anindya Saha, Anandmayee Tej, Hong-Li Liu +19
Using new continuum and molecular line data from the ALMA Three-millimeter Observations of Massive Star-forming Regions (ATOMS) survey and archival VLA, 4.86 GHz data, we present d…
Galactic `Snake' IRDC G11.110.12: a site of multiple hub-filament systems and colliding filamentary clouds
L. K. Dewangan, N. K. Bhadari, A. K. Maity +3
To probe star formation processes, we present a multi-scale and multi-wavelength investigation of the `Snake' nebula/infrared dark cloud G11.110.12 (hereafter, G11; length $\sim…
