LISA stellar-mass black hole searches with semicoherent and particle-swarm methods
Diganta Bandopadhyay, Christopher J. Moore
This paper considers the problem of searching for quiet, long-duration and broadband gravitational wave signals, such as stellar-mass binary black hole binaries, in mock LISA data.…
Stochastic gravitational wave background from supernovae in massive scalar-tensor gravity
Roxana Rosca-Mead, Michalis Agathos, Christopher J. Moore +1
In massive scalar-tensor gravity, core-collapse supernovae are strong sources of scalar-polarized gravitational waves. These can be detectable out to large distance. The dispersive…
On the LISA science performance in observations of short-lived signals from massive black hole binary coalescences
Geraint Pratten, Antoine Klein, Christopher J. Moore +4
The observation of massive black hole binary systems is one of the main science objectives of the Laser Interferometer Space Antenna (LISA). The instrument's design requirements ha…
Searching for a Ringdown Overtone in GW150914
Eliot Finch, Christopher J. Moore
We reanalyze the GW150914 post-merger data searching for quasinormal modes beyond the fundamental, quadrupolar mode. There is currently an ongoing disagreement in the literature ab…
Frequency-Domain Analysis of Black-Hole Ringdowns
Eliot Finch, Christopher J. Moore
We propose a novel, frequency-domain approach to the analysis of the gravitational-wave ringdown signal of binary black holes and the identification of quasinormal mode frequencies…
Population-informed priors in gravitational-wave astronomy
Christopher J. Moore, Davide Gerosa
We describe a Bayesian formalism for analyzing individual gravitational-wave events in light of the rest of an observed population. This analysis reveals how the idea of a "populat…
Testing general relativity with gravitational-wave catalogs: the insidious nature of waveform systematics

Modelling the Ringdown from Precessing Black Hole Binaries
Eliot Finch, Christopher J. Moore
Modelling the end point of binary black hole mergers is a cornerstone of modern gravitational-wave astronomy. Extracting multiple quasinormal mode frequencies from the ringdown sig…

This paper provides an extended exploration of the inverse-chirp gravitational-wave signals from stellar collapse in massive scalar-tensor gravity reported in [Phys. Rev. Lett. {\b…
Astrometric Effects of Gravitational Wave Backgrounds with non-Luminal Propagation Speeds
Deyan P. Mihaylov, Christopher J. Moore, Jonathan Gair +2
A passing gravitational wave causes a deflection in the apparent astrometric positions of distant stars. The effect of the speed of the gravitational wave on this astrometric shift…
