Across the Universe: GW231123 as a magnified and diffracted black hole merger
Srashti Goyal, Hector Villarrubia-Rojo, Miguel Zumalacarregui
GW231123 appears as the most massive binary black hole (BBH) ever observed by the LIGO interferometers with total mass . A high observed mass can be explained by t…
Accelerated inference of microlensed gravitational waves with machine learning
Marienza Caldarola, Srashti Goyal, Nihar Gupte +2
Gravitational waves (GWs) within the LIGO-Virgo-KAGRA sensitivity band can be microlensed by stellar and intermediate-mass black holes, producing a frequency-dependent modulation o…
Dark Matter Subhalos and Higher Order Catastrophes in Gravitational Wave Lensing
Luka Vujeva, Jose María Ezquiaga, Daniel Gilman +2
Gravitational lensing is an invaluable probe of the nature of dark matter, and the structures it forms. Lensed gravitational waves in particular allow for unparalleled sensitivity…
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…
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…
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…
GLoW: novel methods for wave-optics phenomena in gravitational lensing
Hector Villarrubia-Rojo, Stefano Savastano, Miguel Zumalacárregui +4
Wave-optics phenomena in gravitational lensing occur when the signal's wavelength is commensurate to the gravitational radius of the lens. Although potentially detectable in lensed…
A rapid method for preliminary identification of subthreshold strongly lensed counterparts to superthreshold gravitational-wave events
Srashti Goyal, Shasvath Kapadia, Jean-Rene Cudell +2
Gravitational waves (GWs) from stellar-mass compact binary coalescences (CBCs) are expected to be strongly lensed when encountering large agglomerations of matter, such as galaxies…
Probing lens-induced gravitational-wave birefringence as a test of general relativity
Srashti Goyal, Aditya Vijaykumar, Jose Maria Ezquiaga +1
Theories beyond general relativity (GR) modify the propagation of gravitational waves (GWs). In some, inhomogeneities (aka. gravitational lenses) allow interactions between the met…
Rapid Identification of Strongly Lensed Gravitational-Wave Events with Machine Learning
Srashti Goyal, Harikrishnan D., Shasvath J. Kapadia +1
A small fraction of the gravitational-wave (GW) signals that will be detected by second and third generation detectors are expected to be strongly lensed by galaxies and clusters,…
The Science Case for LIGO-India
M. Saleem, Javed Rana, V. Gayathri +12
The global network of gravitational-wave detectors has completed three observing runs with detections of merging compact binaries. A third LIGO detector, with comparable…
Testing the nature of gravitational-wave polarizations using strongly lensed signals
Srashti Goyal, K. Haris, Ajit Kumar Mehta +1
Gravitational-wave (GW) observations by a network of ground-based laser interferometric detectors allow us to probe the nature of GW polarizations. This would be an interesting tes…
DMTPC: A dark matter detector with directional sensitivity
J. B. R. Battat, S. Ahlen, T. Caldwell +18
By correlating nuclear recoil directions with the Earth's direction of motion through the Galaxy, a directional dark matter detector can unambiguously detect Weakly Interacting Mas…
