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…
BB plot: A Tool for Accurate Model Selection Using Bayes factors
Ankur Barsode
A common task in physics and astronomy is studying which of the competing hypotheses the data prefer. This is usually done by computing the Bayes factor between the two hypotheses,…
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…
GWTC-4.0: Searches for Gravitational-Wave Lensing Signatures
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1766
Gravitational waves can be gravitationally lensed by massive objects along their path. Depending on the lens mass and the lens--source geometry, this can lead to the observation of…
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…
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…
