It is expected that gravitational waves, similar to electromagnetic waves, can be gravitationally lensed by intervening matters, producing multiple instances of the same signal arriving at different times from different apparent luminosity distances with different phase shifts compared to the un-lensed signal due to lensing. If unaccounted for, these lensed signals will masquerade as separate systems with higher mass and lower redshift. Here we present a Bayesian statistical framework for… 
Strong lensing: A magnifying glass to detect gravitational-wave microlensing
Microlensing imprints by typical stellar-mass lenses on gravitational waves are challenging to identify in the LIGO–Virgo frequency band because such effects are weak. However, stellar-mass lenses
Gravelamps: Gravitational Wave Lensing Mass Profile Model Selection
We present the package Gravelamps which is designed to analyse gravitationally-lensed gravitational wave signals in order to constrain the mass density profile of the lensing object. Gravelamps does
Modified gravitational wave propagation with higher modes and its degeneracies with lensing
. Low-energy alternatives to General Relativity (GR) generically modify the phase of gravitational waves (GWs) during their propagation. As detector sensitivities increase, it becomes key to

Gravitational lensing of gravitational waves: A statistical perspective
In this paper, we study the strong gravitational lensing of gravitational waves (GWs) from a statistical perspective, with particular focus on the high frequency GWs from stellar binary black hole

Wave Effects in the Gravitational Lensing of Gravitational Waves from Chirping Binaries
In the gravitational lensing of gravitational waves, wave optics should be used instead of geometrical optics when the wavelength λ of the gravitational waves is longer than the Schwarzschild radius
Targeted Sub-threshold Search for Strongly-lensed Gravitational-wave Events
Strong gravitational lensing of gravitational waves can produce duplicate signals that are separated in time with different amplitudes. We consider the case in which strong lensing produces

Strong lensing by intervening galaxies can produce multiple images of gravitational waves from sources at cosmological distances. These images acquire additional phase-shifts as the over-focused
Search for Lensed Gravitational Waves Including Morse Phase Information: An Intriguing Candidate in O2
We search for strongly lensed and multiply imaged gravitational wave signals in the second observing run of Advanced LIGO and Advanced Virgo (O2). We exploit a new source of information, the
Bilby: A User-friendly Bayesian Inference Library for Gravitational-wave Astronomy
TLDR
This work introduces a user-friendly Bayesian inference library for gravitational-wave astronomy, Bilby, and provides a suite of examples for the analysis of compact binary mergers and other types of signal models, including supernovae and the remnants of binary neutron star mergers.

The detailed observation of the distribution of redshifts and chirp masses of binary black hole mergers is expected to provide a clue to their origin. In this paper, we develop a hybrid model of the
Identifying strongly lensed gravitational wave signals from binary black hole mergers
Based on the rate of gravitational-wave (GW) detections by Advanced LIGO and Virgo, we expect these detectors to observe hundreds of binary black hole mergers as they achieve their design
Precise LIGO Lensing Rate Predictions for Binary Black Holes
We show how LIGO is expected to detect coalescing binary black holes at z>1 that are lensed by the intervening galaxy population. Gravitational magnification, μ, strengthens gravitational-wave
