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…

InPars-Light: Cost-Effective Unsupervised Training of Efficient Rankers

Leonid Boytsov, Preksha Patel, Vivek Sourabh +4

We carried out a reproducibility study of InPars, which is a method for unsupervised training of neural rankers (Bonifacio et al., 2022). As a by-product, we developed InPars-light…

A numerical study of the interplay between Fermi acceleration mechanisms in radio lobes of FR-II radio galaxies

Sayan Kundu, Bhargav Vaidya, Andrea Mignone +1

Context: Radio-loud AGNs are thought to possess various sites of particle acceleration, which gives rise to the observed non-thermal spectra. Stochastic turbulent acceleration (STA…

Numerical modeling and physical interplay of stochastic turbulent acceleration for non-thermal emission processes

Sayan Kundu, Bhargav Vaidya, Andrea Mignone

Particle acceleration is an ubiquitous phenomenon in astrophysical and space plasma. Diffusive shock acceleration (DSA) and stochastic turbulent acceleration are known to be the po…
