Probing the cosmic opacity from Future Gravitational Wave Standard Sirens

In this work, using the Gaussian Process, we explore the potentiality of future gravitational wave (GW) measurement to probe cosmic opacity through comparing its opacity-free luminosity distance (LD) with the opacity-dependent one from type Ia supernovae (SNIa). Expand abstract.

Gaussian processes reconstruction of modified gravitational wave propagation

Recent work has shown that modified gravitational wave (GW) propagation can be a powerful probe of dark energy and modified gravity, specific to GW observations. Expand abstract.

High accuracy on $H_0$ constraints from gravitational wave lensing events

In light of the newly opened and rapidly growing GW window in multi-messenger astronomy, in order to fully take advantage of the new opportunities we are provided with, new ideas are required for a better and deeper employ of the state-of-the-art probes we handle. Expand abstract.

Quantum effects in gravity waves

Fluctuations in the electric field due to interaction with a gravitational wave both in a coherent and squeezed states are then calculated, and it is shown that the field experiences infinite revivals of squeezing. Expand abstract.

Gravitational waveforms of binary neutron star inspirals using PN Tidal Splicing

The tidal deformations of neutron stars within an inspiraling compact binary alter the orbital dynamics, imprinting a signature on the gravitational wave signal. Expand abstract.
