Discovery of a rich population of compact hub-filament systems in a single star-forming complex
L. K. Dewangan, Ram K. Yadav, Saurabh Sharma +4
We report the discovery of 45 compact hub-filament systems (HFSs; median size 2.4 pc) in infrared-dark clouds (IRDCs) in the W33 complex, located at the junction of the Scutu…
Investigating Embedded Structures and Gas Kinematics in the IRDC Hosting Bubble N59-North
A. K. Maity, L. K. Dewangan, O. R. Jadhav +5
We present a multi-wavelength study of an extended area hosting the bubble N59-North to explore the physical processes driving massive star formation (MSF). The Spitzer 8 m ima…
Unveiling Physical Conditions and Star Formation Processes in the G47 Filamentary Cloud
O. R. Jadhav, L. K. Dewangan, A. Haj Ismail +6
We present a multi-wavelength study of the filamentary cloud G47 (d 4.44 kpc), which hosts the mid-infrared bubbles N98, B1, and B2. The SMGPS 1.3 GHz continuum map detects i…
JWST-ALMA Study of a Hub-Filament System in the Nascent Phase
N. K. Bhadari, L. K. Dewangan, O. R. Jadhav +7
Star clusters, including high-mass stars, form within hub-filament systems (HFSs). Observations of HFSs that remain unaffected by feedback from embedded stars are rare yet crucial…
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}…
