Probing Dark Matter with Strongly Lensed Binary Black Hole Mergers: Prospects in the Near Future

Koustav N. Maity, Souvik Jana, Ankur Barsode +2

Gravitational-wave~(GW) transients, strongly lensed by intervening galaxies and clusters, are expected to constitute a small fraction (-) of the events detectable…

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,…

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…

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…

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…

Fast and efficient Bayesian method to search for strongly lensed gravitational waves

A. Barsode, S. Goyal, P. Ajith

A small fraction of the gravitational-wave (GW) signals from binary black holes observable by ground-based detectors will be strongly lensed by intervening objects such as galaxies…

Efficient hybrid technique for generating sub-grid haloes in reionization simulations

Ankur Barsode, Tirthankar Roy Choudhury

Simulating the distribution of cosmological neutral hydrogen (HI) during the epoch of reionization requires a high dynamic range and is hence computationally expensive. The size of…

Constraints on compact dark matter from the non-observation of gravitational-wave strong lensing

A. Barsode, S. J. Kapadia, P. Ajith

We use the non-observation of strong lensing of gravitational waves (GWs) in the first three observation runs of LIGO-Virgo detectors to constrain the fraction of dark matter in th…
