Unveiling the importance of magnetic fields in the evolution of dense clumps formed at the waist of bipolar H II regions: a case study on Sh2-201 with JCMT SCUBA-2/POL-2
Chakali Eswaraiah, Di Li, Manash R. Samal +10
We present the properties of magnetic fields (B-fields) in two clumps (clump 1 and clump 2), located at the waist of the bipolar H II region Sh2-201, based on JCMT SCUBA-2/POL-2 ob…
New insights in giant molecular cloud hosting S147/S153 complex: signatures of interacting clouds
J. S. Dhanya, L. K. Dewangan, D. K. Ojha +1
In order to understand the formation of massive OB stars, we report a multi-wavelength observational study of a giant molecular cloud hosting the S147/S153 complex (size ~90 pc X 5…
Influence of Wolf-Rayet stars on surrounding star-forming molecular clouds
T. Baug, Richard de Grijs, L. K. Dewangan +5
We investigate the influence of Wolf-Rayet (W-R) stars on their surrounding star-forming molecular clouds. We study five regions containing W-R stars in the inner Galactic plane ($…
Cluster-forming site AFGL 5157: colliding filamentary clouds and star formation
L. K. Dewangan
We observationally investigate star formation (SF) process occurring in AFGL 5157 (area ~13.5 pc X 13.5 pc) using a multi-wavelength approach. Embedded filaments are seen in the {\…
The Origin of [CII] 158um Emission toward the HII Region Complex S235
L. D. Anderson, Z. Makai, M. Luisi +9
Although the 2P3/2-2P1/2 transition of [CII] at 158um is known to be an excellent tracer of active star formation, we still do not have a complete understanding of where within sta…
Unveiling molecular clouds toward bipolar HII region G8.14+0.23
L. K. Dewangan, H. Sano, R. Enokiya +3
Most recent numerical simulations suggest that bipolar HII regions, powered by O-type stars, can be formed at the interface of two colliding clouds. To observationally understand t…
Observational signatures of end-dominated collapse in the S242 filamentary structure
Lokesh K. Dewangan, Lev E. Pirogov, Olga L. Ryabukhina +2
We present new CO (13CO(1-0) and C18O(1-0)) and CS(2-1) line observations of an elongated filamentary structure (length ~30 pc) in the star-forming site S242, which were taken with…
Evidence of interacting elongated filaments in the star-forming site AFGL 5142
Lokesh K. Dewangan, Devendra K. Ojha, Tapas Baug +1
To probe the ongoing physical mechanism, we studied a wide-scale environment around AFGL 5142 (area ~25 pc x 20 pc) using a multi-wavelength approach. The Herschel column density (…
SCOPE: SCUBA-2 Continuum Observations of Pre-protostellar Evolution - Survey Description and Compact Source Catalogue
D. J. Eden, Tie Liu, Kee-Tae Kim +157
We present the first release of the data and compact-source catalogue for the JCMT Large Program SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE). SCOPE consist…
Cavities, shocks and a cold front around 3C 320
Nilkanth D. Vagshette, Sachindra Naik, Madhav. K. Patil
We present results obtained from the analysis of a total of 110 ks Chandra observations of 3C 320 FR II radio galaxy, located at the centre of a cluster of galaxies at a redshift $…
Implications of a hot atmosphere/corino from ALMA observations towards NGC1333 IRAS 4A1
Dipen Sahu, Sheng-Yuan Liu, Yu-Nung Su +4
We report high angular resolution observations of NGC1333 IRAS4A, a protostellar binary including A1 and A2, at 0.84 mm with the Atacama Large Millimeter/submillimeter Array. From…
