Advanced Virgo during the LIGO-Virgo-KAGRA fourth observing run
Virgo Collaboration, F Acernese, A Agapito +546
The paper reports on Advanced Virgo's participation in the fourth observing run (O4) of the global gravitational‑wave detector network, describing the commissioning of its new sign…
Emergent structure in the binary black hole mass distribution and implications for population-based cosmology
Vasco Gennari, Tom Bertheas, Nicola Tamanini
Gravitational waves provide a powerful probe of both the astrophysical processes driving black hole mergers and the dynamics of the Universe, but these measurements rely on accurat…
Spectral sirens cosmology from binary black holes populations with sharper mass features
Tom Bertheas, Vasco Gennari, Danièle Steer +1
Spectral-sirens inference enables the extraction of cosmological parameters from gravitational-wave data alone, without electromagnetic counterparts or galaxy catalogs. We introduc…
Towards a few percent measurement of the Hubble constant with the current network of gravitational wave detectors without using electromagnetic information
Tom Bertheas, Vasco Gennari, Nicola Tamanini
Gravitational waves provide a novel and independent measurement of cosmological parameters, offering a promising avenue to address the Hubble tension alongside traditional electrom…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +70
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
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…
