Sh 2-301: a blistered H II region undergoing star formation
Rakesh Pandey, Saurabh Sharma, Lokesh K. Dewangan +6
We present a multiwavelength study of the H II region Sh 2-301 (S301) using deep optical data, near-infrared data, radio continuum data and other archival data at longer wavelength…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- V. Hierarchical fragmentation and gas dynamics in IRDC G034.43+00.24
Hong-Li Liu, Anandmayee Tej, Tie Liu +35
We present new 3-mm continuum and molecular lines observations from the ATOMS survey towards the massive protostellar clump, MM1, located in the filamentary infrared dark cloud (IR…
The disk-outflow system around the rare young O-type protostar W42-MME
L. K. Dewangan, I. I. Zinchenko, P. M. Zemlyanukha +6
We present line and continuum observations (resolution ~0.3"-3.5") made with the Atacama Large Millimeter/submillimeter Array (ALMA), Submillimeter Array, and Very Large Array of a…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- IV. Radio Recombination Lines and evolution of star formation efficiencies
C. Zhang, Neal J. Evans, T. Liu +11
We report detection of radio recombination line (RRL) H toward 75 sources, with data obtained from ACA observations in the ATOMS survey of 146 active Galactic star forming…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- VI. On the formation of the "L" type filament in G286.21+0.17
Jian-Wen Zhou, Tie Liu, Jin-Zeng Li +16
Filaments play an important role in star formation, but the formation process of filaments themselves is still unclear. The high-mass star forming clump G286.21+0.17 (G286 for shor…
Probing gas kinematics and PDR structure around O-type stars in Sh 2-305 HII region
N. K. Bhadari, L. K. Dewangan, P. M. Zemlyanukha +3
We report an observational study of the Galactic HII region Sh 2-305/S305 using the [CII] 158 m line data, which are used to examine the gas dynamics and structure of photodisso…
Lynds Bright Nebulae: Sites of possible twisted filaments and ongoing star formation
L. K. Dewangan, J. S. Dhanya, N. K. Bhadari +2
The paper presents an analysis of multi-wavelength data of two Lynds Bright Nebulae (LBN), LBN 140.07+01.64 and LBN 140.771.42. The 1420 MHz continuum map reveals an extended Y-…
ALMA discovery of a dual dense probably rotating outflow from a massive young stellar object G18.88MME
I. I. Zinchenko, L. K. Dewangan, T. Baug +2
We report the discovery of a very dense jet-like fast molecular outflow surrounded by a wide-angle wind in a massive young stellar object (MYSO) G18.88MME (stellar mass 8 M$_…
ATOMS:ALMA Three-millimeter Observations of Massive Star-forming regions -- III :Catalogues of candidate hot molecular cores and Hyper/Ultra compact HII regions
Hong-Li Liu, Tie Liu, Neal J. Evans +50
We have identified 453 compact dense cores in 3 mm continuum emission maps in the ATOMS (ALMA Three-millimeter Observations of Massive Star-forming regions) survey, and compiled th…
Unraveling the inner substructure of new candidate hub-filament system in the HII region G25.4NW
L. K. Dewangan
We present multi-scale and multi-wavelength data of the Galactic HII region G25.4-0.14 (hereafter G25.4NW, distance ~5.7 kpc). The SHARC-II 350 micron continuum map displays a hub-…
Magnetic fields and Star Formation around HII regions: The S235 complex
R. Devaraj, D. P. Clemens, L. K. Dewangan +3
Magnetic fields are ubiquitous and essential in star formation. In particular, their role in regulating formation of stars across diverse environments like HII regions needs to be…
