Simple recipe for the final spin of a binary black hole coalescence
The model in this paper gives us insight into the precise way the final black hole spin relates to properties of the individual black holes. Image Source: SXS Gravitational lensing
Bald Black Holes Wearing Wigs
The No-Hair Theorem is valid in realistic astrophysical contexts: even when engulfed by surrounding matter, a non-rotating black hole resists growing hair.
Hunting for ECOs: Gravitational Wave “Smoking Guns”
Echoes after the initial gravitational wave signal are the “smoking gun” signature of exotic compact objects (ECOs).
Remedy to “Glitch” Size Anomaly
The observed deviation from power law glitch size distributions can be explained using a carefully chosen model that bridges microscopic and macroscopic scales.

The first 10 ms after two neutron stars have merged is the period that produces the loudest gravitational waves in the entire history of the binary.
