On combining information from multiple gravitational wave sources [PDF]
Physical 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: reflections and echoes [PDF]
, 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:

Dirty waveforms: multiband harmonic content of gas-embedded gravitational wave sources [PDF]
, 2021 We analyse the effect of stochastic torque fluctuations on the orbital evolution and the gravitational wave (GW) emission of gas-embedded sources with intermediate and extreme mass ratios.

Shouts and Murmurs: Combining Individual Gravitational-wave Sources with the Stochastic Background to Measure the History of Binary Black Hole Mergers [PDF]
Astrophysical Journal, 2020 One of the goals of gravitational-wave astronomy is to quantify the evolution of the compact binary merger rate with redshift. The redshift distribution of black hole mergers would offer considerable information about their evolutionary history ...

A Systematic Search of Zwicky Transient Facility Data for Ultracompact Binary LISA-detectable Gravitational-wave Sources [PDF]
Astrophysical Journal, 2020 Using photometry collected with the Zwicky Transient Facility, we are conducting an ongoing survey for binary systems with short orbital periods ( with the goal of identifying new gravitational-wave sources detectable by the upcoming Laser Interferometer

Accurate precision cosmology with redshift unknown gravitational wave sources [PDF]
, 2020 Gravitational waves can provide an accurate measurement of the luminosity distance to the source but cannot provide the source redshift unless the degeneracy between mass and redshift can be broken.

Taiji program: Gravitational-wave sources [PDF]
International Journal of Modern Physics A, 2018 We review potential low-frequency gravitational-wave sources, which are expected to be detected by Taiji, a Chinese space-based gravitational-wave detector, estimate the detection rates of these gravitational-wave sources and present the parameter ...

Enhancing gravitational wave anisotropies with peaked scalar sources [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 Gravitational wave (GW) backgrounds of cosmological origin are expected to be nearly isotropic, with small anisotropies resembling those of the cosmic microwave background.

Search Methods for Continuous Gravitational-Wave Signals from Unknown Sources in the Advanced-Detector Era [PDF]
Universe, 2021 Continuous gravitational waves are long-lasting forms of gravitational radiation produced by persistent quadrupolar variations of matter. Standard expected sources for ground-based interferometric detectors are neutron stars presenting non-axisymmetries ...
