Time delay as a probe of multiple photon spheres
Kajol Paithankar, Sanved Kolekar
Black hole shadow images are primarily determined by the properties of photon spheres and can exhibit degeneracies across different spherically symmetric spacetime geometries. We s…
Photon region boundary for stationary axisymmetric black holes
Prasad Padhye, Kajol Paithankar, Sanved Kolekar
The black hole shadow is fundamentally connected to the structure of light rings and the photon region in the background geometry. We investigate the photon region boundary in a ge…
Black hole shadow and acceleration bounds for spherically symmetric spacetimes
Kajol Paithankar, Sanved Kolekar
We explore an interesting connection between black hole shadow parameters and the acceleration bounds for radial linear uniformly accelerated (LUA) trajectories in static spherical…
The role of Unruh effect in Bremsstrahlung
Kajol Paithankar, Sanved Kolekar
An equivalence is demonstrated, by an explicit first order quantum calculation, between the Minkowski photon emission rate in the inertial frame for an accelerating charge moving o…
Rindler horizons in the Schwarzschild spacetime
Kajol Paithankar, Sanved Kolekar
We investigate the past and future Rindler horizons for radial Rindler trajectories in the Schwarzschild spacetime. We assume the Rindler trajectory to be linearly uniformly accele…
Bound on Rindler trajectories in Black Hole spacetime
Kajol Paithankar, Sanved Kolekar
We investigate radial Rindler trajectories in a static spherically symmetric black hole spacetime. We assume the trajectory to remain linearly uniformly accelerated throughout its…
