Cloud Scale Star Formation and Gas Scaling Relations in the Milky Way
Alphesunny Sarkar, Tapas Baug, Ariful Hoque +2
We investigate cloud-scale star formation in the Milky Way using a sample of 45 molecular clouds (sizes of pc) in the inner Galactic plane, spanning heliocentric distances…
The ALMA-QUARKS Survey: Properties of Hot Molecular Fragments in the Massive Protocluster IRAS 17233-3606
Li Chen, Sheng-Li Qin, Dongting Yang +29
To investigate the physical mechanisms of fragmentation within the hot molecular core of the massive protocluster IRAS 17233-3606 (G351.78-0.54), we carried out a detailed analysis…
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{…
ALMA-QUARKS view of W49N: Multipolar episodic outflow associated with the most energetic Galactic water maser
Yunfan Jiao, Tie Liu, Wenyu Jiao +28
We present a detailed investigation of a multipolar episodic molecular outflow in the mini-starburst region W49N, which hosts the most luminous water maser in the Galaxy. Using hig…
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…
