Gravitational waves from compact binary coalescences (CBCs) have become a robust and powerful tool for testing General Relativity (GR), in fact, to date, the LIGO-Virgo-KAGRA collaboration has provided significant consistency tests of GR.

Testing the binary black hole nature of compact binaries relies on the โno-hairโ conjecture, which posits that a Kerr black hole's properties are fully characterized by its mass and spin. This conjecture underpins tests applied to circular compact binaries detected by gravitational wave (GW) detectors, where the quadrupole moment depends solely on mass and spin. In contrast, exotic compact...

65. Detection prospects of parity-violating gravitational waves in third-generation ground detectorsHannah Duval11/11/2025, 16:30Div2talk
We investigate the prospects for detecting a parity-violating gravitational-wave background with third-generation ground-based detector networks through an adapted theoretical approach combined with a data-based approach. We focus on a variety of networks consisting of an Einstein Telescope and two Cosmic Explorer detectors, varying the Einstein Telescope design, detector locations,...

Multi-probe techniques have proven to be powerful tools in modern cosmology.
By breaking degeneracies, they provide new ways to gain insights into the large-scale structure (LSS) of the Universe and its evolution.In this talk, we explore the potential of cross-correlation between gravitational waves (GWs) and 21 cm intensity mapping from neutral hydrogen emission (HI), focusing on its...

The persistence of the Hubble tension requires new validation methods. While gravitational waves provide a promising solution, the rarity of standard sirens has forced to rely on dark sirens and as such, a wealth of dark sirens methods have been developed.
In this talk we will explore our new state-of-the-art models for binary black hole (BBH) merger rates and their applications to...

Disentangling the astrophysical origins of gravitational waves requires confronting population properties of observed source catalogs with theoretical predictions. We investigate the formation of merging binary black holes in two distinct environments: stellar clusters and active galactic nuclei (AGNs). In clusters, repeated three-body interactions determine the dynamical assembly of binaries....

Wide-band searches for continuous gravitational waves are essential to reveal unknown neutron stars without an electromagnetic counterpart. Such searches, however, cover a huge parameter space that makes them computationally bounded. Neutron stars are predicted to slow down their rotation by losing energy through a variety of physical mechanisms, including, e.g, electromagnetic and...

In this work we present the properties of gravitational waves emitted from the f-mode oscillation of a compact star corresponding to the Object HESS J1731-347 as a Twin Compact Star, a hybrid neutron star with the same mass as a larger, purely hadronic neutron star. HESS J1731-347 is a peculiar object due to its reported compactness consisting of a mass of 0.77 solar masses and a radius of...

All-sky searches for continuous gravitational wave signals, like those expected from asymmetric rotating neutron stars, require to analyse long stretches of data in order to increase the signal-to-noise ratio.

Typically, the heavy processing part starts after all the data to be analysed have been collected. Such a strategy is sub-optimal from a computational perspective and can significantly... -

The Einstein Telescope (ET), along with other next-generation gravitational wave (GW) detectors, will be a key instrument for detecting GWs in the coming decades. However, analyzing the data and estimating source parameters will be challenging, especially given the large number of expected detections โ of order $10^5$ per year โ which makes current methods based on stochastic sampling...

Third-generation gravitational wave detectors such as Einstein Telescope and Cosmic Explorer will have significantly better sensitivities than current detectors, as well as a wider frequency bandwidth. This will increase the number and duration of the observed signals, leading to many signals overlapping in time. If not adequately accounted for, this can lead to biases in parameter estimation....

Overlapping gravitational wave (GW) signals are expected in the third-generation (3G) GW detectors, leading to one of the major challenges in GW data analysis. Inference of overlapping GW sources is complicated - it has been reported that hierarchical inference with signal subtraction may amplify errors, while joint estimation, though more accurate, is computationally expensive. However, in...

Gravitational-wave (GW) astronomy has revolutionized our understanding of the universe, but the precision of its discoveries hinges on the accurate calibration of GW detectors. In this talk, we present a novel Bayesian null-stream method for self-calibration of closed-geometry GW detector networks, such as the Einstein Telescope (ET) and LISA. Unlike traditional approaches that rely on...

As gravitational-wave detectors gain sensitivity at low frequencies, inferring source properties becomes challenging due to long-duration signals and high signal-to-noise ratios. With enhanced low-frequency sensitivity, we also expect to observe many more eccentric binaries, with potentially a large impact on our understanding of binaries. The presence of orbital eccentricity enhances the...
