Heavy Black-Holes Also Matter in Standard Siren Cosmology
Grégoire Pierra, Alexander Papadopoulos
With the release of the Gravitational-Wave Transient Catalog GWTC-4.0 by the LIGO-Virgo-KAGRA (LVK) collaboration, 218 candidate detections of gravitational waves (GWs) from compac…
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…
Inferring black hole formation channels in GWTC-4.0 via parametric mass-spin correlations derived from first principles
Emanuele Berti, Francesco Crescimbeni, Gabriele Franciolini +3
We investigate the differences between several proposed formation scenarios for binary black holes (BBHs), including isolated stellar evolution, dynamical assembly in dense cluster…
Non-Parametric Reconstruction of the Hubble Parameter from the Fourth Gravitational Wave Transient Catalog and DESI Baryonic Acoustic Oscillations
Grégoire Pierra, Alberto Colombo, Simone Mastrogiovanni
The release of the fourth Gravitational Wave Transient Catalog (GWTC-4.0) by the LIGO-Virgo-KAGRA collaboration includes more than 200 compact binary coalescence (CBC) candidates t…
Gravitational wave cosmology : an introduction
Grégoire Pierra, Simone Mastrogiovanni
This chapter introduces gravitational wave cosmology, focusing on the use of gravitational waves as standard sirens to probe the expansion history of the Universe. It presents and…
Searching for additional structure and redshift evolution in the observed binary black hole population with a parametric time-dependent mass distribution
Vasco Gennari, Simone Mastrogiovanni, Nicola Tamanini +2
The population of the observed gravitational wave events encodes unique information on the formation and evolution of stellar-mass black holes, from the underlying astrophysical pr…
