LIGO A: Detector Design and Science Prospects Beyond A+
L. Sun, K. Kuns, B. J. J. Slagmolen +1153
We present the LIGO A detector concept, an upgrade for the LIGO observatories based on room-temperature interferometers beyond the fifth observing run (O5). Building on th…

Visualization of time-frequency structures in gravitational wave signals
Chad Henshaw, Megan Arogeti, Alice Heranval +1
The gravitational wave signals produced by the coalescence of compact binaries progress through three stages: inspiral, merger, and postmerger. The evolution of their frequency fol…

Time-frequency structure in the post-merger binary black hole gravitational wave signal
Chad Henshaw, Alice Heranval, Laura Cadonati
Gravitational wave signals from asymmetric binary black hole systems have been shown to exhibit additional chirps beyond the primary merger chirp in the post-merger region of the t…
