Gravitational wave radiation from periodic orbits in regular black holes
Rishav Agrawal, Anjan Kar, Soumya Jana +1
Gravitational wave radiation from periodic orbits in some standard regular black hole spacetimes is studied, primarily using known methods (numerical and analytic). We demonstrate…
A note on the Penrose process in rotating regular black holes
Anjan Kar, Ayan Dey, Sayan Kar
We investigate the Penrose process of energy extraction in the context of rotating regular black holes. For the Neves-Saa class of regular black hole solutions, which includes the…
Diverse regular spacetimes using a parametrised density profile
Anjan Kar, Sayan Kar
We explore the construction of diverse regular spacetimes (black holes and defects) in General Relativity (GR) using a generic parametrised density profile (the Dekel-Zhao profile)…
New rotating Lorentzian wormhole spacetime
Anjan Kar, Soumya Jana, Sayan Kar
A rotating version of a known static, spherically symmetric, zero Ricci scalar Lorentzian wormhole is constructed. It turns out that for this given non-rotating geometry, the stand…
Aspects of a novel nonlinear electrodynamics in flat spacetime and in a gravity-coupled scenario
Anjan Kar
A novel nonlinear electrodynamics (NLE) model with two dimensionful parameters is introduced and investigated. Our model obeys the Maxwellian limit and exhibits behaviour similar t…
