Evolution of starless cores in massive clumps seen by the ALMA ASHES and QUARKS surveys
Dongting Yang, Hong-li Liu, Sheng-li Qin +28
We present a systematic comparative analysis of 324 starless cores in early-phase infrared-dark clouds (IRDCs; ASHES survey) and evolved-phase infrared-bright clouds (IRBCs; QUARKS…
Digging into the Massive Protostar S255IR NIRS3: A Study of Nitrogen-Bearing Molecules and Their Prebiotic Chemistry
Arijit Manna, Sabyasachi Pal, Tapas Baug +4
The study of complex nitrogen (N)-bearing molecules is essential for probing the physical and chemical evolution of star-forming regions. In this paper, we present the identificati…
Discovery of a Compact Hub-Filament System in G286.21+0.17 with JWST and ALMA: Insights into Protocluster Formation and Competitive Accretion
L. K. Dewangan, N. K. Bhadari, Ram K. Yadav +17
We present a multi-wavelength study of the massive protocluster G286.21+0.17 (G286) using \emph{JWST} near-infrared imaging and ALMA HCO(1--0) observations. The \emph{…
The ALMA-QUARKS Survey: Evidence of an Explosive Molecular Outflow in IRAS 15520--5234
Ariful Hoque, Tapas Baug, Estrella Guzman +25
We present a study of the massive protocluster IRAS 155205234, which displays evidence of an explosive molecular outflow that unleashed a kinetic energy of at least 10 er…
ATOMS-QUARKS survey: Inflow and infall in massive protocluster G318.049+00.086: Evidence of competitive accretion
Shivani Gupta, Tapas Baug, Archana Soam +17
We present a gas kinematic study of the massive protocluster G318.049+00.086. The protocluster is reported to contain 12 prestellar core candidates and 4 protostellar cores. Filame…
The ALMA-ATOMS Survey: Exploring Protostellar Outflows in HCN
Ariful Hoque, Tapas Baug, Lokesh K. Dewangan +25
We present the first systematic study of bipolar outflows using HCN as a tracer in a sample of 146 massive star-forming regions from ALMA-ATOMS survey. Protostellar outflows ar…
