Phase consistency test to identify type II strongly lensed gravitational wave signals using a single event
Kelsie Taylor, Derek Davis, Rico K. L. Lo
For gravitationally lensed type II signals, the phase of the dominant (2, 2) mode and the higher order (3, 3) mode is offset by , or roughly -0.26 radians. Using this, we de…
Recipes for computing radiation from a Kerr black hole using a generalized Sasaki-Nakamura formalism: Homogeneous solutions
Rico K. L. Lo
Central to black hole perturbation theory calculations is the Teukolsky equation that governs the propagation and the generation of radiation emitted by Kerr black holes. However,…
Follow-up Analyses to the O3 LIGO-Virgo-KAGRA Lensing Searches
Justin Janquart, Mick Wright, Srashti Goyal +28
Along their path from source to observer, gravitational waves may be gravitationally lensed by massive objects. This results in distortions of the observed signal which can be used…
Using overlap of sky localization probability maps for filtering potentially lensed pairs of gravitational-wave signals
Henry W. Y. Wong, Lok W. L. Chan, Isaac C. F. Wong +2
Strong gravitational lensing creates multiple images of a gravitational wave transient. The current state-of-the-art method for identifying such lensing events is a computationally…
Angular emission patterns of remnant black holes
Xiang Li, Ling Sun, Rico Ka Lok Lo +2
The gravitational radiation from the ringdown of a binary black hole merger is described by the solution of the Teukolsky equation, which predicts both the temporal dependence and…
Investigation of the effects of non-Gaussian noise transients and their mitigation in parameterized gravitational-wave tests of general relativity
Jack Y. L. Kwok, Rico K. L. Lo, Alan J. Weinstein +1
The detection of gravitational waves from compact binary coalescence by Advanced LIGO and Advanced Virgo provides an opportunity to study the strong-field, highly relativistic regi…
Null-stream-based Bayesian Unmodeled Framework to Probe Generic Gravitational-wave Polarizations
Isaac C. F. Wong, Peter T. H. Pang, Rico K. L. Lo +2
We present a null-stream-based Bayesian unmodeled framework to probe generic gravitational-wave polarizations. Generic metric theories allow six gravitational-wave polarization sta…
Gravitational-wave echoes from spinning exotic compact objects: numerical waveforms from the Teukolsky equation
Shuo Xin, Baoyi Chen, Rico K. L. Lo +7
We present numerical waveforms of gravitational-wave echoes from spinning exotic compact objects (ECOs) that result from binary black hole coalescence. We obtain these echoes by so…
Bayesian statistical framework for identifying strongly lensed gravitational-wave signals
Rico K. L. Lo, Ignacio Magana Hernandez
It is expected that gravitational waves, similar to electromagnetic waves, can be gravitationally lensed by intervening matters, producing multiple instances of the same signal arr…
Identifying Type II Strongly Lensed Gravitational-Wave Images in Third-Generation Gravitational-Wave Detectors
Yijun Wang, Rico K. L. Lo, Alvin K. Y. Li +1
Strong gravitational lensing is a gravitational wave (GW) propagation effect that influences the inferred GW source parameters and the cosmological environment. Identifying strongl…
Generic searches for alternative gravitational wave polarizations with networks of interferometric detectors
Peter T. H. Pang, Rico K. L. Lo, Isaac C. F. Wong +2
The detection of gravitational wave signals by Advanced LIGO and Advanced Virgo enables us to probe the polarization content of gravitational waves. In general relativity, only ten…
Targeted Sub-threshold Search for Strongly-lensed Gravitational-wave Events
Alvin K. Y. Li, Rico K. L. Lo, Surabhi Sachdev +4
Strong gravitational lensing of gravitational waves can produce duplicate signals separated in time with different amplitudes. We consider the case in which strong lensing produces…
The GstLAL Search Analysis Methods for Compact Binary Mergers in Advanced LIGO's Second and Advanced Virgo's First Observing Runs
Surabhi Sachdev, Sarah Caudill, Heather Fong +26
After their successful first observing run (September 12, 2015 - January 12, 2016), the Advanced LIGO detectors were upgraded to increase their sensitivity for the second observing…
Fast evaluation of multi-detector consistency for real-time gravitational wave searches
Chad Hanna, Sarah Caudill, Cody Messick +17
Gravitational waves searches for compact binary mergers with LIGO and Virgo are presently a two stage process. First, a gravitational wave signal is identified. Then, an exhaustive…
