Uncovering the hidden physical structures and protostellar activities in the Low-Metallicity S284-RE region: results from ALMA and JWST
O. R. Jadhav, L. K. Dewangan, Aayushi Verma +4
We present an observational study of the S284-RE region, a low-metallicity area associated with the extended S284 HII region. A thermally supercritical filament (mass 2402 $M…
Mon R2: A Hub-Filament System with an Infrared Bubble at the Hub center
L. K. Dewangan, N. K. Bhadari, A. K. Maity +3
A multi-wavelength, multi-scale study of the Mon R2 hub-filament system (HFS) reveals a spiral structure, with the central hub containing more mass than its filaments. ALMA C$^{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…
ATOMS: ALMA three-millimeter observations of massive star-forming regions -- XVIII. On the origin and evolution of dense gas fragments in molecular shells of compact HII regions
Siju Zhang, Tie Liu, Ke Wang +16
Fragmentation and evolution for the molecular shells of the compact HII regions are less explored compared to their evolved counterparts. We map nine compact HII regions with a typ…
The ALMA-QUARKS Survey: Fibers' role in star formation unveiled in an intermediate-mass protocluster region of the Vela D cloud
Dongting Yang, HongLi Liu, Tie Liu +32
In this paper, we present a detailed analysis of the IRS 17 filament within the intermediate-mass protocluster IRAS 08448-4343 (of ), using ALMA data fro…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions XVII. High-mass star-formation through a large-scale collapse in IRAS 153945358
Swagat R. Das, Manuel Merello, Leonardo Bronfman +23
Hub-filament systems are considered as natural sites for high-mass star formation. Kinematic analysis of the surroundings of hub-filaments is essential to better understand high-ma…
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…
Investigating the Star-forming Sites in the Outer Galactic Arm
Aayushi Verma, Saurabh Sharma, Lokesh K. Dewangan +7
We aim to investigate the global star formation scenario in star-forming sites AFGL 5157, [FSR2007] 0807 (hereafter FSR0807), [HKS2019] E70 (hereafter E70), [KPS2012] MWSC 0620 (he…
Influence of mid-infrared Galactic bubble on surroundings: A case study on IRAS 16489-4431
Ariful Hoque, Tapas Baug, Lokesh Dewangan +3
We studied the influence of a massive star on a mid-infrared bubble and its surrounding gas in the IRAS\,16489-4431 star-forming region using multi-wavelength data. The {\it Spitze…
Extraction of YSO Cores and Active Regions near Star-forming Site AFGL 5157
Aayushi Verma, Saurabh Sharma, Lokesh Dewangan
We have carried out a quantitative analysis of the region near star-forming site AFGL 5157 using 'Minimal Spanning Tree' (MST). The analysis reveals th…
Turbulence and Magnetic Fields in Star Formation
Archana Soam, Chakali Eswaraiah, Amit Seta +2
Molecular clouds are prime locations to study the process of star formation. These clouds contain filamentary structures and cores, which are crucial sites for the formation of you…
Deciphering the Hidden Structures of HH 216 and Pillar IV in M16: Results from JWST and HST
L. K. Dewangan, O. R. Jadhav, A. K. Maity +6
To probe the star formation process, we present an observational investigation of the Pillar IV and an ionized knot HH 216 in the Eagle Nebula (M16). Pillar IV is known to host a C…
The ALMA-QUARKS survey: Detection of two extremely dense substructures in a massive prestellar core
Xiaofeng Mai, Tie Liu, Xunchuan Liu +32
Only a handful of massive starless core candidates have been discovered so far, but none of them have been fully confirmed. Within the MM1 clump in the filamentary infrared dark cl…
