Quasi-normal modes ratios as agnostic test of general relativity
Nicola Franchini
In this letter, we provide a novel test of general relativity based on ringdown analysis. The test is performed on agnostic models, where the postmerger signal is fitted with a sup…
GWTC-4.0: Population Properties of Merging Compact Binaries
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1805
We detail the population properties of merging compact objects using 158 mergers from the cumulative Gravitational-Wave Transient Catalog 4.0, which includes three types of binary…
Black Hole Spectroscopy and Tests of General Relativity with GW250114
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration
The binary black hole signal GW250114, the loudest gravitational wave detected to date, offers a unique opportunity to test Einstein's general relativity (GR) in the high-velocity,…
GW230814: investigation of a loud gravitational-wave signal observed with a single detector
The LIGO Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration +1783
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…
GWTC-4.0: Methods for Identifying and Characterizing Gravitational-wave Transients
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1809
The Gravitational-Wave Transient Catalog (GWTC) is a collection of candidate gravitational-wave transient signals identified and characterized by the LIGO-Virgo-KAGRA Collaboration…
GWTC-4.0: An Introduction to Version 4.0 of the Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1808
The Gravitational-Wave Transient Catalog (GWTC) is a collection of short-duration (transient) gravitational wave signals identified by the LIGO-Virgo-KAGRA Collaboration in gravita…
GW231123: a Binary Black Hole Merger with Total Mass 190-265
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1771
On 2023 November 23 the two LIGO observatories both detected GW231123, a gravitational-wave signal consistent with the merger of two black holes with masses $137^{+23}_{-18}\, M_\o…
Black hole quasinormal mode resonances
Yiqiu Yang, Emanuele Berti, Nicola Franchini
Black hole quasinormal mode frequencies can be very close to each other ("avoided crossings") or even completely degenerate ("exceptional points") when the system is characterized…
Search for continuous gravitational waves from known pulsars in the first part of the fourth LIGO-Virgo-KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1816
Continuous gravitational waves (CWs) emission from neutron stars carries information about their internal structure and equation of state, and it can provide tests of General Relat…
