Advanced Virgo during the LIGO-Virgo-KAGRA fourth observing run
Virgo Collaboration, F Acernese, A Agapito +546
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 KAG…
Post-Newtonian inspiral waveform model for eccentric precessing binaries with higher-order modes and matter effects
Gonzalo Morras, Geraint Pratten, Patricia Schmidt +1
We introduce pyEFPEHM, a post-Newtonian (PN) inspiral waveform model for eccentric and spin-precessing compact binaries that includes higher-order modes and matter effects. Accurat…
Advanced Virgo Plus for O5 -- Design Report Overview
F. Acernese, A. Agapito, D. Agarwal +578
This document presents an overview of the design, implementation, and expected performance of the Advanced Virgo Plus (AdV+) upgrades in view of the O5 observing run. Following the…
Impact of eccentricity on the population properties of neutron star - black hole mergers
Gonzalo Morras, Geraint Pratten, Patricia Schmidt
We revisit the population properties of neutron star-black hole (NSBH) mergers using low-mass compact binary coalescences reported through GWTC-4. Employing pyEFPE, an inspiral-onl…
Astrophysical Implications of Eccentricity in Gravitational Waves from Neutron Star-Black Hole Binaries
Isobel Romero-Shaw, Jakob Stegmann, Gonzalo Morras +2
The gravitational-wave signal from the neutron star-black hole (NSBH) merger GW200105 is consistent with this binary having significant orbital eccentricity close to merger. This r…
Detection of GW200105 with a targeted eccentric search
Khun Sang Phukon, Patricia Schmidt, Gonzalo Morras +1
The neutron star -- black hole (NSBH) binary GW200105 was recently found to have significant residual orbital eccentricity at a gravitational-wave frequency of 20 Hz~\cite{Morras:2…
Modeling Gravitational Wave Modes from the Inspiral of Binaries with Arbitrary Eccentricity
Gonzalo Morras
Eccentric binaries are key targets for current and future gravitational wave (GW) detectors, offering unique insights into the formation and environments of compact binaries. Howev…
Orbital eccentricity in a neutron star - black hole merger
Gonzalo Morras, Geraint Pratten, Patricia Schmidt
The observation of gravitational waves from merging black holes and neutron stars provides a unique opportunity to discern information about their astrophysical environment. Two si…
Improved post-Newtonian waveform model for inspiralling precessing-eccentric compact binaries
Gonzalo Morras, Geraint Pratten, Patricia Schmidt
The measurement of spin-precession and orbital eccentricity in gravitational-wave (GW) signals is a key priority in GW astronomy, as these effects not only provide insights into th…
Effects of local cosmic inhomogeneities on the gravitational wave event rate
Gonzalo Morras, Juan Garcia-Bellido
The local universe is highly inhomogeneous and anisotropic. We live in a relatively sparse region of the Laniakea supercluster at the edge of a large 80 Mpc-wide void. We study the…
Applying the Viterbi Algorithm to Planetary-Mass Black Hole Searches
George Alestas, Gonzalo Morras, Takahiro S. Yamamoto +3
The search for subsolar mass primordial black holes (PBHs) poses a challenging problem due to the low signal-to-noise ratio, extended signal duration, and computational cost demand…
Efficient Reduced Order Quadrature Construction Algorithms for Fast Gravitational Wave Inference
Gonzalo Morras, Jose Francisco Nuno Siles, Juan Garcia-Bellido
Reduced Order Quadrature (ROQ) methods can greatly reduce the computational cost of Gravitational Wave (GW) likelihood evaluations, and therefore greatly speed up parameter estimat…
