Probing globular clusters parameters through gravitational wave lensing with stellar-mass black hole binaries
Sreekanth Harikumar, Abbas Askar, MichaÅ Bejger +3
Globular clusters (GCs) can act as gravitational lenses for gravitational waves(GWs) in the wave-optics regime, imprinting frequency-dependent signatures on the observed signal. We…
Fundamental Physics and Cosmology with TianQin
Jun Luo, Haipeng An, Ligong Bian +33
The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this g…
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…
Weak Lensing Approximation of Wave-optics Effects from General Symmetric Lens Profiles
Zhao-Feng Wu, Otto A. Hannuksela, Martin Hendry +1
Gravitational lensing of electromagnetic (EM) waves has yielded many profound discoveries across fundamental physics, astronomy, astrophysics, and cosmology. Similar to EM waves, g…
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…
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…
