Abstract GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is consistent with a binary black hole coalescence with component masses m 1 = 33 . 7 …

We present directed searches for continuous gravitational waves from the neutron stars in the Cassiopeia A (Cas A) and Vela Jr. supernova remnants. We carry out the searches in the LIGO data from the first six months of the third Advanced LIGO …

We compare GW150914 directly to simulations of coalescing binary black holes in full general relativity, including several performed specifically to reproduce this event. Our calculations go beyond existing semianalytic models, because for all simulations---including sources with two independent, precessing spins---we perform comparisons …

We present results of a search for continuously emitted gravitational radiation, directed at the brightest low-mass x-ray binary, Scorpius X-1. Our semicoherent analysis covers 10 days of LIGO S5 data ranging from 50--550 Hz, and performs an incoherent sum of coherent $\mathcal{F}$-statistic …

Searches for a stochastic gravitational-wave background (SGWB) using terrestrial detectors typically involve cross-correlating data from pairs of detectors. The sensitivity of such cross-correlation analyses depends, among other things, on the separation between the two detectors: the smaller the separation, the better the …

Gravitational waves from a variety of sources are predicted to superpose to create a stochastic background. This background is expected to contain unique information from throughout the history of the Universe that is unavailable through standard electromagnetic observations, making its study of …

This paper presents results of an all-sky search for periodic gravitational waves in the frequency range $[50,1\text{ }190]\text{ }\text{ }\mathrm{Hz}$ and with frequency derivative range of $\ensuremath{\sim}[\ensuremath{-}20,1.1]\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}10}\text{ }\text{ }\mathrm{Hz}\text{ }{\mathrm{s}}^{\ensuremath{-}1}$ for the fifth LIGO science run (S5). The search uses a noncoherent …

We present the results of a weakly modeled burst search for gravitational waves from mergers of nonspinning intermediate mass black holes in the total mass range $100--450\text{ }\text{ }{\mathrm{M}}_{\ensuremath{\bigodot}}$ and with the component mass ratios between $1\ensuremath{\mathbin:}1$ and $4\ensuremath{\mathbin:}1$. The search was …
