Inference with finite time series: II. The window strikes back Open
Smooth window functions are often applied to strain data when inferring the parameters describing the astrophysical sources of gravitational-wave transients. Within the LIGO-Virgo-KAGRA collaboration, it is conventional to include a term t…

Progress toward the detection of the gravitational-wave background from stellar-mass binary black holes: a mock data challenge Open
While the third LIGO--Virgo gravitational-wave transient catalog includes 90 signals, it is believed that ${\cal O}(10^5)$ binary black holes merge somewhere in the Universe every year. Although these signals are too weak to be detected in…

The Stochastic Siren: Astrophysical Gravitational-Wave Background Measurements of the Hubble Constant Open
Gravitational waves from individually resolved compact object mergers can be used as standard sirens, offering a novel self-calibrating precision probe of cosmology. While the standard siren method has been well-explored, the gravitational…

Better early than never: A new test for superluminal gravitational wave polarizations Open
In some beyond-Einstein theories of gravity, gravitational waves can contain up to six polarizations, which are allowed to propagate at different speeds faster than light. These different propagation speeds imply that polarizations generat…
