A stepping stone toward detecting gravitational wave memory: a cumulative analysis with the full spherical harmonic using events from GWTC-4.0 and GWTC-5.0

Maria Rosselló-Sastre, Sascha Husa, Yumeng Xu +3

We perform Bayesian model selection to test for the presence of the spherical harmonic mode in gravitational wave events that have previously been identified as bina…

Remnant recoil and host environments of GWTC-4.0 binary black-hole mergers

Joan Llobera-Querol, Eleanor Hamilton, Neha Singh +8

Determining the astrophysical origin of binary black holes and whether merger remnants are retained in their birth environments is essential for understanding hierarchical mergers…

Parameter estimation for the GWTC-4.0 catalog with phenomenological waveform models that include orbital eccentricity and an updated description of spin precession

Yumeng Xu, Jorge Valencia, Héctor Estellés Estrella +11

The GWTC-4.0 catalog of transient gravitational wave signals describes observations made in the first part of the fourth observing run of the LIGO-Virgo-KAGRA (LVK) gravitational w…

Optimizing searches for gravitational wave bursts using coherent WaveBurst 2G

Alessandro Martini, Andrea Miani, Marco Drago +11

The most general searches for gravitational wave transients (GWTs) rely on data analysis methods that do not assume prior knowledge of the signal waveform, direction, or arrival ti…

Impact of the spherical harmonic mode with memory on parameter estimation for ground-based detectors

Maria Rosselló-Sastre, Sascha Husa, Sayantani Bera +1

We recently presented an efficient and accurate waveform model for the spherical harmonic mode including both the displacement memory contribution and the ringdown oscillat…

Enhancing Gravitational Wave Parameter Estimation with Non-Linear Memory: Breaking the Distance-Inclination Degeneracy

Yumeng Xu, Maria Rosselló-Sastre, Shubhanshu Tiwari +5

In this study, we investigate the role of the non-linear memory effect in gravitational wave (GW) parameter estimation, particularly we explore its capability to break the degenera…

Search for hyperbolic encounters of compact objects in the third LIGO-Virgo-KAGRA observing run

Sophie Bini, Shubhanshu Tiwari, Yumeng Xu +6

Gravitational-wave (GW) observations provide unique information about compact objects. As detectors sensitivity increases, new astrophysical sources of GW could emerge. Close hyper…
