Magnetic Prandtl number dependence of plasmoid-mediated reconnection
Vinay Kumar, Axel Brandenburg
We investigate the dependence of the plasmoid-mediated magnetic reconnection rate on the magnetic Prandtl number using two-dimensional magnetohydrodynamic simulations of two coales…

Three-dimensional tearing instability of flux-tube-like magnetic fields
Vinay Kumar, Pallavi Bhat
Magnetic reconnection, a fundamental plasma process, is pivotal in understanding energy conversion and particle acceleration in astrophysical systems. While extensively studied in…

Closure invariants for polarised radio interferometric observations: a graph theoretical approach
Vinay Kumar, Rajaram Nityananda, Joseph Samuel
Aperture synthesis observations with full polarisation have long been used to study the magnetic fields of synchrotron emitting sources. Recently proposed closure invariants give u…
