The impact of strong lensing on Hubble constant measurements with gravitational-wave dark sirens
Eungwang Seo, Kyungmin Kim, Zhuotao Li +3
The disagreement between early and late Universe electromagnetic measurements of the Hubble constant, , known as the Hubble tension, highlights the need for independent and co…
LensingFlow: An Automated Workflow for Gravitational Wave Lensing Analyses
Mick Wright, Justin Janquart, Paolo Cremonese +18
In this work, we present LensingFlow. This is an implementation of an automated workflow to search for evidence of gravitational lensing in a large series of gravitational wave eve…
Residual test to search for microlensing signatures in strongly lensed gravitational wave signals
Eungwang Seo, Xikai Shan, Justin Janquart +3
When a gravitational wave signal encounters a massive object, such as a galaxy or galaxy cluster, it undergoes strong gravitational lensing, producing multiple copies of the origin…
Detectability of lensed gravitational waves in matched-filtering searches
Juno C. L. Chan, Eungwang Seo, Alvin K. Y. Li +2
Gravitational lensing by compact, small-scale intervening masses causes frequency-dependent distortions to gravitational-wave events. The optimal signal-to-noise ratio (SNR) is oft…
Multi-messenger Gravitational Lensing
Graham P. Smith, Tessa Baker, Simon Birrer +38
We introduce the rapidly emerging field of multi-messenger gravitational lensing - the discovery and science of gravitationally lensed phenomena in the distant universe through the…
