No definitive lensing is detected in GW231123, though a potential microlensing feature with modulation amplitude up to 0.8 at 95% confidence is noted, limited by large waveform systematics in short signals.
Detection of GW190814 from the coalescence of a 23 solar-mass black hole and a 2.6 solar-mass compact object, the most unequal-mass binary yet observed with gravitational waves.
A Gaussian process framework with a localized-deviation kernel is used to test general relativity on simulated and GWTC-3 binary black hole signals, finding no evidence for deviations and limiting strain deviations to 7% for one event.
In a viable f(R) model transitioning from early GR-like to late non-GR behavior, matter power spectra show higher monopole and quadrupole power at small scales with quadrupole elevated at large scales up to k~0.02, while scalaron mass decreases over time to GR limits on galactic scales.
No credible isolated black hole candidates were found in a Gaia DR3 search within 15 pc of the Sun after multi-wavelength checks dismissed five sources as probable artifacts.
BILBY is validated on simulated compact binary signals and reproduces the eleven GWTC-1 results with configuration and output files provided for reproduction.

Cosmological perturbations with $f(R)$ gravity scalarons : Galaxy power spectra and the scalaron mass
In a viable f(R) model transitioning from early GR-like to late non-GR behavior, matter power spectra show higher monopole and quadrupole power at small scales with quadrupole elevated at large scales up to k~0.02, while scalaron mass decreases over time to GR limits on galactic scales.
