Microlenses with typical stellar masses (a few M⊙) have traditionally been disregarded as potential sources of gravitational lensing effects at LIGO/Virgo frequencies, since the time delays are often much smaller than the inverse of the frequencies probed by LIGO/Virgo, resulting in negligible interference effects at LIGO/Virgo frequencies. While this is true for isolated microlenses in this mass regime, we show how, under certain circumstances and for realistic scenarios, a population of… Expand
Lensing by primordial black holes: Constraints from gravitational wave observations
Primordial black holes (PBHs) have been proposed to explain at least a portion of dark matter. Observations have put strong constraints on PBHs in terms of the fraction of dark matter which they canExpand

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 lensesExpand
Gravitational lensing of gravitational waves: wave nature and prospects for detection
We discuss the gravitational lensing of gravitational wave signals from coalescing binaries. We delineate the regime where wave effects are significant from the regime where geometric limit can beExpand
Small-scale shear: Peeling off diffuse subhalos with gravitational waves
Subhalos at subgalactic scales (M . 10M or k & 10 Mpc−1) are pristine testbeds of dark matter (DM). However, they are too small, diffuse and dark to be visible, in any existing observations. In thisExpand
Identifying type II strongly lensed gravitational-wave images in third-generation gravitational-wave detectors
Strong gravitational lensing is a gravitational wave (GW) propagation effect that influences the inferred GW source parameters and the cosmological environment. Identifying strongly-lensed GW imagesExpand

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-waveExpand

Gravitational waves can be focussed by the gravity of an intervening galaxy, just like light, thereby magnifying binary merging events in the far Universe. High magnification by galaxies is found toExpand
What if LIGO's gravitational wave detections are strongly lensed by massive galaxy clusters?

TLDR
This work discusses strong gravitational lensing of gravitational waves from the merging of massive black hole binaries in the context of the LISA mission, and suggests probabilities to observe multiple events are sizable for a broad range of formation histories. Expand
