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…
Constraints on ultralight bosons from merging binary and remnant black holes observed during the second and third parts of the fourth LIGO-Virgo-KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1808
We present constraints on ultralight bosons using binary black hole mergers observed in the second and third parts of the fourth LIGO-Virgo-KAGRA observing run. Directed searches a…
Probability of gravitational-wave lensing by intermediate-mass black holes and globular clusters
Luka Vujeva, Jose María Ezquiaga, Rico K. L. Lo +1
Strongly lensed gravitational waves (GWs) are powerful probes of substructure in the lens. Intermediate-mass black holes (IMBHs) are postulated to be efficient lenses that may dist…
GWTC-5.0: Tests of General Relativity
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1822
The signals from the LIGO-Virgo-KAGRA network of gravitational-wave (GW) detectors allow us to perform sensitive tests of general relativity (GR) in the dynamical and strong-field…
Discovering gravitational waveform distortions from lensing: A deep dive into GW231123
Juno C. L. Chan, Jose MarÃa Ezquiaga, Rico K. L. Lo +3
Gravitational waves (GWs) are unique messengers as they travel through the Universe without alteration except for gravitational lensing. Their long wavelengths make them susceptibl…
Sub-Torque-Balance Upper Limits on Continuous Gravitational Waves from Scorpius X-1
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1836
We present the results of a search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO data from the first part of the fourth LIGO-Virgo-KAGRA…
