When models fail: An introduction to posterior predictive checks and model misspecification in gravitational-wave astronomy [PDF]

open access: yesPublications Astronomical Society of Australia, 2022
Bayesian inference is a powerful tool in gravitational-wave astronomy. It enables us to deduce the properties of merging compact-object binaries and to determine how these mergers are distributed as a population according to mass, spin, and redshift.

Progress towards gravitational-wave astronomy [PDF]

open access: bronzeClassical and Quantum Gravity, 2008
I will review the most recent and interesting results from gravitational wave detection experiments, concentrating on recent results from the LIGO Scientific Collaboration (LSC). I will outline the methodologies utilized in the searches, explain what can be said in the case of a null result, what quantities may be constrained.

Nanohertz gravitational wave astronomy during SKA era: An InPTA perspective [PDF]

open access: yesJournal of astrophysics and astronomy, 2022
Decades long monitoring of millisecond pulsars, which exhibit highly stable rotational periods in pulsar timing array experiments is on the threshold of discovering nanohertz stochastic gravitational wave background.

Do unequal-mass binary black hole systems have larger $\chi_\text{eff}$? Probing correlations with copulas in gravitational-wave astronomy [PDF]

open access: yes, 2022
The formation history of binary black hole systems is imprinted on the distribution of their masses, spins, and eccentricity. While much has been learned studying these parameters in turn , recent studies have explored the joint distribution of binary ...

Gaussian processes for Glitch-robust Gravitational-wave astronomy [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
Interferometric gravitational-wave observatories have opened a new era in astronomy. The rich data produced by an international network enables detailed analysis of the curved space-time around black holes.

A Broadband Signal Recycling Scheme for Approaching the Quantum Limit from Optical Losses

open access: yesGalaxies, 2021
Quantum noise limits the sensitivity of laser interferometric gravitational-wave detectors. Given the state-of-the-art optics, the optical losses define the lower bound of the best possible quantum-limited detector sensitivity.

Bilby: A User-friendly Bayesian Inference Library for Gravitational-wave Astronomy [PDF]

open access: yesAstrophysical Journal Supplement Series, 2018
Bayesian parameter estimation is fast becoming the language of gravitational-wave astronomy. It is the method by which gravitational-wave data is used to infer the sources’ astrophysical properties. We introduce a user-friendly Bayesian inference library

Model exploration in gravitational-wave astronomy with the maximum population likelihood [PDF]

open access: yesPhysical Review Research, 2022
Hierarchical Bayesian inference is an essential tool for studying the population properties of compact binaries with gravitational waves. The basic premise is to infer the unknown prior distribution of binary black hole and/or neutron star parameters ...
