- [hal-05746424] 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
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 are conducted for long-transient gravitational waves from ultralight vector boson clouds around merger remnants, using a […]
- [hal-05743970] GWTC-5.0: Methods for Identifying and Characterizing Gravitational-wave Transients
The Gravitational-Wave Transient Catalog (GWTC) is a collection of candidate gravitational-wave transient signals identified and characterized by the LIGO-Virgo-KAGRA Collaboration. Producing the contents of the GWTC from detector data requires complex analysis methods. These comprise techniques to […]
- [hal-05743968] Sub-Torque-Balance Upper Limits on Continuous Gravitational Waves from Scorpius X-1
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 observing run. By applying the resampling version of the cross-correlation pipeline to search for signal frequencies […]
- [hal-05742478] Fluxtube Bouquets and Type-1.5 Clustering in Superfluid Neutron Star Cores
We study mesoscopic configurations of a neutron superfluid coupled to a proton superconductor in the outer core of a neutron star. The condensates are described by a two-component Ginzburg-Landau free energy with local couplings, neglecting genuine phase-gradient entrainment. In two spatial […]
- [hal-05741167] Advanced Virgo during the LIGO-Virgo-KAGRA fourth observing run
From April 10, 2024 to November 18, 2025 Advanced Virgo participated in the fourth observing run of the network of gravitational-wave detectors, together with Advanced LIGO and KAGRA. For this observing run Advanced Virgo has completed its design optical configuration with the installation of a […]
- [hal-05741166] GWTC-5.0: Tests of General Relativity
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 regime of gravity. We present the results of seven tests of GR using the observed binary signals in the fifth GW […]

- Live from Mesopotamia, 4,000 years agoThe oldest private correspondence in human history is about marriages and divorces, trade and tax evasion, livestock breeding or weaving… Women’s voices stamped in clay four millennia ago offer eerily topical accounts of the affairs of the day.
- The many tricks of roaming cellsThe ability of a cell to move underpins several biological processes, including healing and cancer. Several CNRS teams are trying to unravel the molecular mechanisms in play.
- Jewish presence predates Islam in ArabiaThe discovery of a previously unknown village in a region of Saudi Arabia that was thought to be only sparsely populated during Late Antiquity reveals the presence of sedentary Jewish communities just before the advent of Islam. The archaeologist Jérôme Rohmer tells CNRS News about this finding.
- The brain knows the scoreBehind the pleasure of listening to a song lies an astonishing brain activity: an anticipatory mechanism that translates simple vibrations into emotions. A phenomenon that is especially used in electronic music.
- Maths and the beachHoliday-makers cross paths at the beach, but so do multiple facets of physics and mathematics. Three research projects are working to better describe this environment so highly sensitive to climate change.
