Star-forming site RAFGL 5085: Is a perfect candidate of hub-filament system ?
L. K. Dewangan, N. K. Bhadari, A. K. Maity +4
To investigate the star formation process, we present a multi-wavelength study of a massive star-forming site RAFGL 5085, which has been associated with the molecular outflow, HII…
Ionized filaments and ongoing physical processes in massive star-forming sites around l = 345.5 degree
L. K. Dewangan, L. E. Pirogov, N. K. Bhadari +1
Numerous research studies on dust and molecular filaments have been conducted in star-forming sites, but only a limited number of studies have focused on ionized filaments. To obse…
Fragmented atomic shell around S187 HII region and its interaction with molecular and ionized gas
Petr Zemlyanukha, Igor I. Zinchenko, Evgeny Dombek +6
The environment of S187, a nearby H II region (1.40.3 kpc), is analyzed. A surrounding shell has been studied in the H I line, molecular lines, and also in infrared and radio…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- XI. From inflow to infall in hub-filament systems
Jian-Wen Zhou, Tie Liu, Neal J. Evans +37
We investigate the presence of hub-filament systems in a large sample of 146 active proto-clusters, using HCO J=1-0 molecular line data obtained from the ATOMS survey.…
Unraveling the observational signatures of cloud-cloud collision and hub-filament systems in W31
A. K. Maity, L. K. Dewangan, H. Sano +3
To understand the formation process of massive stars, we present a multi-scale and multi-wavelength study of the W31 complex hosting two extended HII regions (i.e., G10.30-0.15 (he…
New evidences in IRDC G333.73+0.37: colliding filamentary clouds, hub-filament system, and embedded cores
L. K. Dewangan
To unravel the star formation process, we present a multi-scale and multi-wavelength study of the filamentary infrared dark cloud (IRDC) G333.73+0.37, which hosts previously known…
Simultaneous evidence of edge collapse and hub-filament configurations: A rare case study of a Giant Molecular Filament G45.3+0.1
N. K. Bhadari, L. K. Dewangan, D. K. Ojha +2
We study multiwavelength and multiscale data to investigate the kinematics of molecular gas associated with the star-forming complexes G045.49+00.04 (G45E) and G045.14+00.14 (G45W)…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions-IX. A pilot study towards IRDC G034.43+00.24 on multi-scale structures and gas kinematics
Hong-Li Liu, Anandmayee Tej, Tie Liu +21
We present a comprehensive study of the gas kinematics associated with density structures at different spatial scales in the filamentary infrared dark cloud, G034.43+00.24 (G34). T…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- VII. A catalogue of SiO clumps from ACA observations
Rong Liu, Tie Liu, Gang Chen +28
To understand the nature of SiO emission, we conducted ACA observations of the SiO (2-1) lines toward 146 massive star-forming regions, as part of the ALMA Three-millimeter Observa…
