The No-Hair Theorem is valid in realistic astrophysical contexts: even when engulfed by surrounding matter, a non-rotating black hole resists growing hair.
Echoes after the initial gravitational wave signal are the “smoking gun” signature of exotic compact objects (ECOs).
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.
