We study the scattering of monochromatic planar scalar waves in a geometry that
interpolates between the Schwarzschild solution, regular black holes and traversable …

This study revisits the absorption and scattering process by which a massless scalar field
impinges on a charged-dilatonic black hole. First, we review the classical analysis to obtain …

We study the scattering of axially incident massless scalar waves by a charged and rotating
black hole solution from heterotic string theory called the Kerr-Sen black hole. We compute …

Wave propagations in the presence of black holes is a significant problem both in theoretical
and observational aspects, especially after the discovery of gravitational wave and …

Tidal forces are most significant feature of geodesic deviation in General Relativity. The
astrophysical significance within tidal forces, standpoints out tidal disruption events. We …

In this thesis we study the propagation of scalar and gravitational waves on compact body
spacetimes. In particular, we consider spacetimes that model neutron stars, black holes, and …

In this paper, we study the radial and angular tidal forces in the vicinity of rotating ModMax
black hole. The radial tidal forces intensify with an increase in charge but diminish as the …
