GWTC-5.0: Constraints on the Cosmic Expansion Rate and Modified Gravitational-wave Propagation
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1810
We employ 236 gravitational-wave (GW) sources in the fifth LIGO--Virgo--KAGRA Collaboration (LVK) Gravitational-Wave Transient Catalog (GWTC-5.0) to estimate the Hubble constant $H…
Pushing spectral siren cosmology into the third-generation era: a blinded mock data challenge
Matteo Tagliazucchi, Michele Moresco, Alessandro Agapito +6
Gravitational wave (GW) spectral sirens offer a promising method for measuring cosmological parameters using GW data only - without relying on external redshift information such as…
Mind the peak: improving cosmological constraints from GWTC-4.0 spectral sirens using semiparametric mass models
Matteo Tagliazucchi, Michele Moresco, Nicola Borghi +1
Gravitational wave spectral sirens can provide cosmological constraints by using the shape of the binary black hole (BBH) mass distribution (MD). However, the precision and accurac…
A new path to constrain the expansion history of the Universe in future spectroscopic galaxy surveys
Elena Tomasetti, Michele Moresco, Nicola Borghi +6
The current tension between early- and late-Universe measurements of the Hubble constant (), along with the still elusive nature of dark matter and dark energy, calls for mode…
Echoes from the dark: Galaxy catalog incompleteness in standard siren cosmology
Nicola Borghi, Michele Moresco, Matteo Tagliazucchi +1
Gravitational wave observations can be combined with galaxy catalogs to constrain cosmology and test modified gravity theories using the standard siren method. However, galaxy cata…
Accelerating the standard siren method: Improved constraints on modified gravitational-wave propagation with future data
Matteo Tagliazucchi, Michele Moresco, Nicola Borghi +1
Gravitational waves (GWs) from compact binary mergers have emerged as one of the most promising probes of cosmology and General Relativity (GR). However, a major challenge in fully…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Cosmology and Astrophysics with Standard Sirens and Galaxy Catalogs in View of Future Gravitational Wave Observations
Nicola Borghi, Michele Mancarella, Michele Moresco +4
With the growing number of gravitational-wave detections and the advent of large galaxy redshift surveys, a new era in cosmology is unfolding. This study explores the synergies bet…
A new measurement of the expansion history of the Universe at z=1.26 with cosmic chronometers in VANDELS
E. Tomasetti, M. Moresco, N. Borghi +6
We derive a new constraint on the expansion history of the Universe by applying the cosmic chronometers method, studying the age evolution of high-redshift galaxies with a full-spe…
New Observational Data from Full-Spectrum Fitting of Cosmic Chronometers in the LEGA-C Survey
Kang Jiao, Nicola Borghi, Michele Moresco +1
In this work, we perform a full-spectrum fitting of 350 massive and passive galaxies selected as cosmic chronometers from the LEGA-C ESO public survey to derive their stellar ages,…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Toward a Better Understanding of Cosmic Chronometers: A new measurement of H(z) at z~0.7
Nicola Borghi, Michele Moresco, Andrea Cimatti
We analyze the stellar ages obtained from a combination of Lick indices in Borghi et al. for 140 massive and passive galaxies selected in the LEGA-C survey at . From the…
