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…
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…
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{…
Large HI optical depth and Redshifted 21-cm signal from cosmic dawn
Kanan K. Datta, Raghunath Ghara, Ariful Hoque +1
The HI 21-cm optical depth () can be considerably large as the kinetic and spin temperature of the inter-galactic medium (IGM) is expected to be very low during cosmic dawn.…
Prediction of bank transaction fraud using TabNet an adaptive deep learning architecture
Prashanth BS, Manoj Kumar, Ariful Hoque +4
The development of online banking has brought about an increase in fraudulent operations, which is a major problem for banks. This study delves into the urgent requirement for inte…
