Accelerated inference of microlensed gravitational waves with machine learning Open
Gravitational waves (GWs) propagating through the universe can be microlensed by stellar and intermediate-mass objects. Lensing induces frequency-dependent amplification of GWs, which can be computed using \texttt{GLoW}, an accurate code s…

Dark Matter Subhalos and Higher Order Catastrophes in Gravitational Wave Lensing Open
Gravitational lensing is an invaluable probe of the nature of dark matter, and the structures it forms. Lensed gravitational waves in particular allow for unparalleled sensitivity to small scale structures within the lenses, due to the pre…

Gravitational lensing of waves: Novel methods for wave-optics phenomena Open
Wave-optics phenomena in gravitational lensing occur when the signal’s wavelength is commensurate to the gravitational radius of the lens. Although potentially detectable in lensed gravitational waves, fast radio bursts and pulsars, accura…
