A numerical study on the role of instabilities on multi-wavelength emission signatures of blazar jets
Sriyasriti Acharya, Bhargav Vaidya, Indu Kalpa Dihingia +2
Blazars, a class of active galaxies whose jets are relativistic and collimated flows of plasma directed along the line of sight and are prone to a slew of magneto-hydrodynamic (MHD…
Acceleration of cosmic rays in presence of magnetohydrodynamic fluctuations at small scales
Sayan Kundu, Nishant Singh, Bhargav Vaidya
This work investigates the evolution of the distribution of charged particles due to the mechanism of stochastic turbulent acceleration (STA) in presence of small-scale turbulence…
A Volumetric Study of Flux Transfer Events at the Dayside Magnetopause
Arghyadeep Paul, Bhargav Vaidya, Antoine Strugarek
Localized magnetic reconnection at the dayside magnetopause leads to the production of Flux Transfer Events (FTEs). The magnetic field within the FTEs exhibit complex helical flux-…
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…
Truncated accretion discs in black hole X-ray binaries: dynamics and variability signatures
Indu K. Dihingia, Bhargav Vaidya, Christian Fendt
Variable features in black hole X-ray Binaries (BH-XRBs) are observed in different energy ranges and time scales. The physical origin of different spectral states in BH-XRBs and th…
SWASTi-SW: Space Weather Adaptive SimulaTion framework for Solar Wind and its relevance to ADITYA-L1 mission
Prateek Mayank, Bhargav Vaidya, D. Chakrabarty
Solar wind streams, acting as background, govern the propagation of space weather drivers in the heliosphere, which induce geomagnetic storm activities. Therefore, predictions of t…
Dynamical Modelling and Emission Signatures of a Candidate Dual AGN with Precessing Radio Jets
Gourab Giri, Ravi Pratap Dubey, K. Rubinur +2
In this paper, we have modelled the dynamical and emission properties (in the presence of radiative losses and diffusive shock acceleration) of an observed S-shaped radio source (2…
Modelling X-shaped Radio Galaxies: Dynamical and Emission Signatures from the Back-flow model
Gourab Giri, Bhargav Vaidya, Paola Rossi +3
Some of the radio galaxies show distortion in their jets, forming tailed or winged sources. X-shaped radio galaxies are a subclass of winged sources formation mechanism of which is…
