Gravitational-wave Sources from Mergers of Binary Black Holes Catalyzed by Flyby Interactions in the Field [PDF]

open access: yesAstrophysical Journal, 2019
Several scenarios were suggested for the origins of gravitational-wave (GW) sources from mergers of stellar binary black holes (BBHs). Here we propose a novel origin through catalyzed formation of GW sources from ultra-wide binaries in the field.

Waltzing Binaries: Probing the Line-of-sight Acceleration of Merging Compact Objects with Gravitational Waves

open access: yesThe Astrophysical Journal, 2023
The line-of-sight acceleration of a compact binary coalescence (CBC) event would modulate the shape of the gravitational waves (GWs) it produces with respect to the corresponding nonaccelerated CBC.

On combining information from multiple gravitational wave sources [PDF]

open access: yesPhysical Review D, 2019
In the coming years, advanced gravitational wave detectors will observe signals from a large number of compact binary coalescences. The majority of these signals will be relatively weak, making the precision measurement of subtle effects, such as ...

Gravitational wave sources from inspiralling globular clusters in the Galactic Centre and similar environments [PDF]

open access: yes, 2018
We model the inspiral of globular clusters (GCs) towards a galactic nucleus harboring a supermassive black hole (SMBH), a leading scenario for the formation of nuclear star clusters.We consider the case of GCs containing either an intermediate-mass ...

A Search for Gravitational Waves from Perturbed Black Hole Ringdowns in LIGO Data [PDF]

open access: yes, 2008
According to General Relativity a perturbed black hole will return to a stable configuration by the emission of gravitational radiation in a superposition of quasi-normal modes. Such a perturbation will occur due to the coalescence of a black hole binary,

Research Note: The Expected Spins of Gravitational Wave Sources With Isolated Field Binary Progenitors [PDF]

open access: yes, 2017
We explore the consequences of dynamical evolution of field binaries composed of a primary black hole (BH) and a Wolf-Rayet (WR) star in the context of gravitational wave (GW) source progenitors.

Mass–redshift degeneracy for the gravitational-wave sources in the vicinity of supermassive black holes [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2017
Retrieving the mass of a gravitational-wave (GW) source is a fundamental but difficult problem because the mass is degenerate with redshift. In astronomy, three types of redshift exist, namely cosmological, Doppler, and gravitational redshift, but the ...

All-sky search for short gravitational-wave bursts in the second Advanced LIGO and Advanced Virgo run

open access: yes, 2022
We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo.

Gravitational wave sources: reflections and echoes [PDF]

open access: yes, 2017
The recent detection of gravitational waves has generated interest in alternatives to the black hole interpretation of sources. A subset of such alternatives involves a prediction of gravitational wave ‘echoes’. We consider two aspects of possible echoes:

Probing anisotropies of the Stochastic Gravitational Wave Background with LISA [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2022
We investigate the sensitivity of the Laser Interferometer Space Antenna (LISA) to the anisotropies of the Stochastic Gravitational Wave Background (SGWB).
