Suspicious Siblings: The Distribution of Mass and Spin across Component Black Holes in Isolated Binary Evolution Authors: Zevin, Michael & Bavera, Simone S. (2022) Abstract: The LIGO and Virgo gravitational-wave detectors have uncovered binary black hole systems with definitively nonzero spins, as well as systems with significant spin residing in the more massive black hole…

Gravitational wave signal from primordial magnetic fields in the Pulsar Timing Array frequency band Authors: Roper Pol, Alberto; Caprini, Chiara; Neronov, Andrii; Semikoz, Dmitri (2022) Abstract: The NANOGrav, Parkes, European, and International Pulsar Timing Array (PTA) Collaborations have reported evidence for a common-spectrum process that can potentially correspond to a stochastic gravitational wave background (SGWB)…

Modified gravitational wave propagation and the binary neutron star mass function Authors: Finke, Andreas; Foffa, Stefano; Iacovelli, Francesco; Maggiore, Michele; Mancarella, Michele (2022) Abstract: Modified gravitational wave (GW) propagation is a generic phenomenon in modified gravity. It affects the reconstruction of the redshift of coalescing binaries from the luminosity distance measured by GW detectors, and…

Gravitational-wave cosmology with dark sirens: state of the art and perspectives for 3G detectors Authors: Mancarella, Michele; Borghi, Nicola; Foffa, Stefano; Genoud-Prachex, Edwin; Iacovelli, Francesco; Maggiore, Michele; Moresco, Michele; Schulz, Matteo (2022) Abstract: A joint fit of the mass and redshift distributions of the population of Binary Black Holes detected with Gravitational-Wave observations can be…

Cosmology and modified gravitational wave propagation from binary black hole population models Authors: Mancarella, Michele; Genoud-Prachex, Edwin; Maggiore, Michele (2022) Abstract: A joint hierarchical Bayesian analysis of the binary black hole (BBH) mass function, merger rate evolution, and cosmological parameters can be used to extract information on both the cosmological and population parameters. We extend…

Cosmology and modified gravity with dark sirens from GWTC-3 Authors: Mancarella, Michele; Finke, Andreas; Foffa, Stefano; Genoud-Prachex, Edwin; Iacovelli, Francesco; Maggiore, Michele (2022) Abstract: We present the latest measurements of the Hubble parameter and of the parameter $\Xi_0$ describing modified gravitational wave propagation, obtained from the third gravitational wave transient catalog, GWTC-3, using the correlation…
