Many distant objects can only be detected, or become more scientifically valuable, if they have been highly magnified by strong gravitational lensing. We use eagle and bahamas, two recent cosmological hydrodynamical simulations, to predict the probability distribution for both the lens mass and lens redshift when point sources are highly magnified by gravitational lensing. For sources at a redshift of two, we find the distribution of lens redshifts to be broad, peaking at z ≈ 0.6. The…

Localizing merging black holes with sub-arcsecond precision using gravitational-wave lensing
The current gravitational-wave (GW) localization methods rely mainly on sources with electromagnetic counterparts. Unfortunately, a binary black hole does not emit light. Due to this, it is
Inferring the lensing rate of LIGO–Virgo sources from the stochastic gravitational wave background
Strong lensing of gravitational waves is more likely for distant sources but predicted event rates are highly uncertain with many astrophysical origins proposed. Here we open a new avenue to estimate
On building a cluster watchlist for identifying strongly lensed supernovae, gravitational waves and kilonovae
Motivated by discovering strongly-lensed supernovae, gravitational waves, and kilonovae in the 2020s, we investigate whether to build a watch-list of clusters based on observed cluster properties
Strong and weak lensing of Gravitational Waves: a semi-analytical approach
In this paper we study gravitational lensing of gravitational wave events. The main point of the present work is to introduce a semi-analytic approach so that each ingredient can be varied and tested
Constraining the Lensing of Binary Black Holes from Their Stochastic Background.
A surprising connection between the lensing of individual transients and limits to the background radiation produced by the unresolved population of binary back hole mergers is exploited: it is shown that it constrains the fraction of individually resolvable lensed binary black holes to less than ∼4×10^{-5} at present sensitivity.
LENSINGGW: a PYTHON package for lensing of gravitational waves
Advanced LIGO and Advanced Virgo could observe the first lensed gravitational waves in the coming years, while the future Einstein Telescope could observe hundreds of lensed events. Ground-based

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

Gravitational lensing of extended high-redshift sources by dark matter haloes
ABSTRA C T High-redshift galaxies and quasi-stellar objects (QSOs) are most likely to be strongly lensed by intervening haloes between the source and the observer. In addition, a large fraction of
Strong-lensing optical depths in a ΛCDM universe – II. The influence of the stellar mass in galaxies
We investigate how strong gravitational lensing in the concordanceCDM cosmology is affected by the stellar mass in galaxies. We extend our previous studies, based on ray trac- ing through the
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

Effects of Disks on Gravitational Lensing by Spiral Galaxies
Gravitational lensing of a quasar by a spiral galaxy should often be accompanied by damped Lyα absorption and dust extinction due to the intervening gaseous disk. In nearly edge-on configurations,

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 to
