Across the Universe: GW231123 as a magnified and diffracted black hole merger
A parameter-estimation analysis of GW231123 under lensed and unlensed models, finding it the first compelling candidate for a magnified and diffracted black-hole merger. The posterior samples behind every model and waveform combination are public.

Signatures of 10–10⁴ M☉ dark-matter halos in LISA via stochastic diffraction
Many low-mass halos along the line of sight leave a collective diffraction imprint whose fluctuations are captured by an orthogonal basis: the "dark timbre". Detectability is forecast for massive black-hole binaries observed by LISA.
Effective description of lensed gravitational waves diffracted by stellar fields
Microlensing amplification curves from simulated stellar fields are compressed into an orthonormal basis, with a distribution for its coefficients that serves as a realization-based prior. The basis can be used for microlensing searches in data.
Where an analysis has companion code or a data release, it is on the Software and data page. The full publication record of the Principal Investigator, including work outside the project, is on INSPIRE-HEP.
