Search for planetary-mass ultracompact binaries using data from the first part of the LIGO–Virgo–KAGRA fourth observing run

A.G Abac, I Abouelfettouh, F Acernese, K Ackley et autres

We present a search for gravitational waves from inspiraling, planetary-mass ultracompact binaries using data from the first part of the fourth observing run of LIGO, Virgo, and KAGRA. Finding no evidence of such systems, we determine the maximum distance reach for such …

Directional search for persistent gravitational waves: Results from the first part of LIGO-Virgo-KAGRA’s fourth observing run

A.G Abac, I Abouelfettouh, F Acernese, K Ackley et autres

The angular distribution of gravitational-wave power from persistent sources may exhibit anisotropies arising from the large-scale structure of the Universe.This motivates directional searches for astrophysical and cosmological gravitational-wave backgrounds, as well as continuous-wave emitters.We present results of such a search using data …

GW240925 and GW250207: Astrophysical Calibration of Gravitational-wave Detectors

A. Abac, I. Abouelfettouh, F. Acernese, K. Ackley et autres

GW240925 and GW250207 are two loud gravitational-wave signals from binary black hole coalescences observed with network signal-to-noise ratios and , respectively, by the LIGO Hanford--LIGO Livingston--Virgo network. Gravitational-wave signals from coalescing binaries have characteristic phase and amplitude evolution predicted by general relativity. …
