Along with redshift dependence BBH rate, mass BBHs can also exhibit due different channels metallicity parent stars.

Given size and expected noise produced by lunar seismic background, LGWA would be able observe GWs from about 1 mHz Hz. This make missing link between space-borne detectors like LISA with peak sensitivities around few millihertz future terrestrial Einstein Telescope or Cosmic Explorer. In this article, we provide first...

We present GLADE+, an extended version of the GLADE galaxy catalogue introduced in our previous paper for multimessenger searches with advanced gravitational-wave detectors. GLADE+ combines data from six separate but not independent astronomical catalogues: GWGC, 2MPZ, 2MASS XSC, HyperLEDA, and WISExSCOSPZ catalogues, SDSS-DR16Q quasar catalogue. To allow corrections CMB-frame redshifts peculiar motions, we calculated velocities along their standard deviations all galaxies having $B$-band...

Abstract We outline the “dark siren” galaxy catalog method for cosmological inference using gravitational wave (GW) standard sirens, clarifying some common misconceptions in implementation of this method. When a confident transient electromagnetic counterpart to GW event is unavailable, identification unique host general challenging. Instead, as originally proposed by Schutz, one can consult and implement dark siren statistical approach incorporating all potential galaxies within...
We investigate the synergy of upcoming galaxy surveys and gravitational wave (GW) experiments in constraining late-time cosmology, examining cross-correlations between weak lensing waves (GW-WL) fields. Without focusing on any specific GW detector configuration, we benchmark requirements for high-precision measurement cosmological parameters by considering several scenarios, varying number detected events uncertainty inference source luminosity distance redshift. focus $\Lambda$CDM...

General relativity (GR) predicts concordant trajectories for photons and gravitational waves (GWs). We propose a new multimessenger avenue (GW-CMB-CMB) to prove this aspect of fundamental physics by cross-correlating the GW signal astrophysical origin with lensing field derived from cosmic microwave background (CMB). This window will allow robust measurement prediction GR high signal-to-noise ratio be able unveil true nature gravity using sources detected missions such as Laser...
