Search for strong lensing of gravitational waves in the binary black hole events from O1-O4a
Ankur Barsode, Koustav N. Maity, Parameswaran Ajith
A small fraction of the gravitational waves (GWs) currently observable by LIGO, Virgo, and KAGRA (LVK) may be strongly lensed by intervening galaxies and galaxy clusters, potential…

Strong lensing cosmography using binary-black-hole mergers: Prospects for the near future
Koustav N. Maity, Souvik Jana, Tejaswi Venumadhav +2
A small fraction of gravitational-wave (GW) signals from binary black holes (BBHs) will be gravitationally lensed by intervening galaxies and galaxy clusters. Strong lensing will p…

Lensing, not luck! Detection prospects of strongly lensed gravitational waves
A. Barsode, K. N. Maity, P. Ajith
A small fraction of gravitational-wave (GW) signals detected by ground-based observatories will be strongly lensed by intervening galaxies or clusters. This may produce multiple co…
