The past decades have witnessed a lot of progress in gravitational lensing with two main
targets: stars and galaxies (with active galactic nuclei). The success is partially attributed to …

The first successful detection of gravitational waves (GWs) opened up a new window to
study a realm of the most violent phenomena in the universe, such as coalescences of …

The gravitational waves emitted by massive black hole binaries in the Laser Interferometer
Space Antenna (LISA) band can be lensed. Wave-optics effects in the lensed signal are …

When gravitational waves pass near massive astrophysical objects, they can be
gravitationally lensed. The lensing can split them into multiple wave fronts, magnify them, or …

Gravitational lensing by massive objects along the line of sight to the source causes
distortions of gravitational wave-signals; such distortions may reveal information about …

Strong gravitational lensing of gravitational waves (GWs) has been forecasted to become
detectable in the upcoming LIGO/Virgo/KAGRA observing runs. However, definitively …

Similarly to light, gravitational waves can be gravitationally lensed as they propagate near
massive astrophysical objects such as galaxies, stars, or black holes. In recent years …

Owing to the forecasted improved sensitivity of ground-based gravitational-wave detectors,
new research avenues will become accessible. This is the case for gravitational-wave strong …

Since the first detection of gravitational waves in 2015, gravitational-wave astronomy has
emerged as a rapidly advancing field that holds great potential for studying the cosmos, from …

Gravitational lensing offers unique opportunities to learn about the astrophysical origin of
distant sources, the abundance of intervening objects acting as lenses, and gravity and …
