Probing globular clusters parameters through gravitational wave lensing with stellar-mass black hole binaries
Sreekanth Harikumar, Abbas Askar, MichaÅ 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, PaweÅ CiecielÄ g +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…
