On the Presence of a Tertiary Compact Object in GW190814
Lalit Pathak, Hemantakumar Phurailatpam, Achamveedu Gopakumar
Gravitational waves from merging compact binaries are sensitive to line-of-sight acceleration (LOSA) induced by a massive companion in their vicinity. Interestingly, the leading-or…
Joint Bayesian Source and Lens Reconstruction for Multi-messenger Binary Black Holes
Laura Uronen, Tian Li, Justin Janquart +5
If a gravitational wave event is lensed by a cluster or galaxy in our line-of-sight, it is expected that its host galaxy would also be lensed. Therefore, connecting lensed gravitat…
Strong gravitational-wave lensing posterior odds
Otto A. Hannuksela, K. Haris, Justin Janquart +4
Like light, gravitational waves are gravitationally lensed by intervening massive astrophysical objects, such as galaxies, clusters, black holes, and stars, resulting in a variety…
Constraining initial orbital eccentricity of inspiral-dominated gravitational-wave events with an analytic approximant
Hemantakumar Phurailatpam, Gopakumar Achamveedu, Maria Haney +2
The LIGO-Virgo-KAGRA consortium has sporadically detected inspiral-dominated gravitational-wave events such as GW170817 and GW190425. These events offer an opportunity to constrain…
Gravitational lensing: towards combining the multi-messengers
Anupreeta More, Hemantakumar Phurailatpam
The next generation of gravitational wave detectors and electromagnetic telescopes are beckoning the onset of the multi-messenger era and the exciting science that lies ahead. Mult…
gwsnr: A Python package for efficient signal-to-noise ratio calculations of gravitational waves
Hemantakumar Phurailatpam, Otto Akseli Hannuksela
is a Python package for efficient signal-to-noise ratio and detectability calculations for compact-binary gravitational-wave sources. It is designed for large simulated pop…
What is the nature of GW230529? An exploration of the gravitational lensing hypothesis
Justin Janquart, David Keitel, Rico K. L. Lo +26
On the 29th of May 2023, the LIGO-Virgo-KAGRA Collaboration observed a compact binary coalescence event consistent with a neutron star-black hole merger, though the heavier object…
ler: LVK (LIGO-Virgo-KAGRA collaboration) event (compact-binary mergers) rate calculator and simulator
Hemantakumar Phurailatpam, Anupreeta More, Harsh Narola +6
ler is a Python package for simulating compact-binary gravitational-wave populations and estimating detectable event rates for current and future LIGO-Virgo-KAGRA detector networks…
Finding Black Holes: an Unconventional Multi-messenger
Laura E. Uronen, Tian Li, Justin Janquart +5
A rather clear problem has remained in black hole physics: localizing black holes. One of the recent theoretical ways proposed to identify black hole mergers' hosts is through mult…
Uncovering faint lensed gravitational-wave signals and reprioritizing their follow-up analysis using galaxy lensing forecasts with detected counterparts
Leo C. Y. Ng, Justin Janquart, Hemantakumar Phurailatpam +4
Like light, gravitational waves can be gravitationally lensed by massive astrophysical objects. Strong gravitational lensing by galaxies and galaxy clusters is anticipated to becom…
Characterizing Gravitational Wave Detector Networks: From A to Cosmic Explorer
Ish Gupta, Chaitanya Afle, K. G. Arun +44
Gravitational-wave observations by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo have provided us a new tool to explore the Universe on all scales from n…
Cosmic Explorer: A Submission to the NSF MPSAC ngGW Subcommittee
Matthew Evans, Alessandra Corsi, Chaitanya Afle +73
Gravitational-wave astronomy has revolutionized humanity's view of the universe, a revolution driven by observations that no other field can make. This white paper describes an obs…
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…
