Probing globular clusters parameters through gravitational wave lensing with stellar-mass black hole binaries

Sreekanth Harikumar, Abbas Askar, Michał Bejger +3

Globular clusters (GCs) can act as gravitational lenses for gravitational waves(GWs) in the wave-optics regime, imprinting frequency-dependent signatures on the observed signal. We…

Microlensing of long-duration gravitational wave signals originating from Galactic sources

Sudhagar Suyamprakasam, Sreekanth Harikumar, Paweł Ciecieląg +3

Detection of quasi-monochromatic, long-duration (continuous) gravitational wave radiation emitted by, e.g., asymmetric rotating neutron stars in our Galaxy requires a long observat…

Propagation and lensing of gravitational waves in Palatini gravity

Sreekanth Harikumar, Laur Järv, Margus Saal +2

Accelerated expansion of the Universe prompted searches of modified gravity theory beyond general relativity, instead of adding a mysterious dark energy component with exotic physi…

Probing massive gravitons in with lensed gravitational waves

Vipin Kumar Sharma, Sreekanth Harikumar, Margherita Grespan +2

We investigate the novel features of gravitational wave solutions in gravity under proper gauge considerations in the shifted Ricci scalar background curvature ().…

Moffat's Modified Gravity tested on X-COP galaxy clusters

Sreekanth Harikumar, Marek Biesiada

Scalar Tensor Vector Gravity(STVG) is a fully covariant Lorentz invariant alternative theory of gravity also called as MOdified Gravity(MOG) which modifies General Relativity(GR) w…
