Gravitational wave research presents a range of intriguing challenges, each of which has
driven significant progress in the field. Key research problems include glitch classification …

Along their path from source to observer, gravitational waves may be gravitationally lensed
by massive objects leading to distortion in the signals. Searches for these distortions …

Strongly lensed gravitational waves (GWs) from binary coalescence manifest as repeated
chirps from the original merger. At the detectors, the phase of the lensed GWs and its arrival …

Gravitational lensing is the phenomenon where the presence of matter (called a lens) bends
the path of light-like trajectories travelling nearby. Similar to the geometric optics limit of …

It has been recently shown that quadruply lensed gravitational-wave (GW) events due to
coalescing binaries can be localized to one or just a few galaxies, even in the absence of an …

By the end of the next decade, we hope to have detected strongly lensed gravitational
waves by galaxies or clusters. Although there exist optimal methods for identifying lensed …

Gravitational wave (GW) galaxy lens reconstruction is a crucial step for many GW lensing
science applications. However, dark siren GW lensing without observed electromagnetic …

When travelling from their source to the observer, gravitational waves can get deflected by
massive objects along their travel path. For a massive lens and a good source-lens …

We present the result of the first deep learning–based search for the signature of
microlensing in gravitational waves. This search seeks the signature induced by lenses with …

Strong lensing of gravitational-wave signals can produce three types of images, denoted as
type-I, type-II, and type-III, corresponding to the minima, saddle, and maxima, respectively, of …
