390 gravitational-wave events: what's new in the biggest catalog yet?

The LIGO-Virgo-KAGRA network has released its largest catalog update, bringing the total confirmed gravitational-wave events to 390. The haul from April 2024 to January 2025 alone added 150 candidates, all consistent with black hole mergers — none involving neutron stars. Standout event GW250114_082203 achieved a signal-to-noise ratio above 70, a new record that will sharpen tests of general relativity in the strong-field regime.
