Moving-mesh simulations of spreading dynamics and local electron cooling in structured gamma-ray burst afterglow jets
Sayan Kundu, Hendrik van Eerten
We present the results for the dynamics and emission profiles of axi-symmetric numerical simulations of structured gamma-ray burst afterglow jets, computed using the relativistic m…

Galactic-scale evolution of classical and complex radio galaxies. Impact of ambient morphology and jet geometry
Gourab Giri, Prajnadipt Ghosh, Ravi Joshi +9
Extragalactic jets exhibit a wide range of propagation orientations relative to the host galaxy's principal axis. This study investigate the spatiotemporal evolution of jets as a f…

Surface Flux Transport Modeling using Physics Informed Neural Networks
Jithu J Athalathil, Bhargav Vaidya, Sayan Kundu +2
Studying the magnetic field properties on the solar surface is crucial for understanding the solar and heliospheric activities, which in turn shape space weather in the solar syste…
