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…
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…
Search for strong lensing of gravitational waves in the binary black hole events from O1-O4a
Ankur Barsode, Koustav N. Maity, Parameswaran Ajith
A small fraction of the gravitational waves (GWs) currently observable by LIGO, Virgo, and KAGRA (LVK) may be strongly lensed by intervening galaxies and galaxy clusters, potential…
Could the high-mass black holes from gravitational-wave observations be explained by lensing?
Ritesh Harshe, R. Prasad, Parameswaran Ajith
The high-mass () black holes (BHs) from the gravitational-wave (GW) observations of LIGO and Virgo came as a surprise to many astronomers. While the collapse…
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…
