“…Kilonova AT 2017gfo and GRB 170817A [32][33][34][35][36][37][38][39][40][41] were the first EM counterparts found to be associated with a GW source, GW170817 [42]. With the precise localization, the host galaxy NGC 4993 was identified and the redshift could be determined (z ∼ 0.009).…”

“…The detection of GW from compact binary mergers has opened a new window to the Universe. The ∼100 events detected by the end of the LVK third observing run have resulted in constraints on deviations from general relativity [175], inference of cosmological parameters [107], revelations about neutron star properties [32,33,[176][177][178][179] and measurement of the population properties of compact binary mergers [180]. However, based on the current estimates of the local merger rates and the redshift distribution of compact binary mergers, more than a million such events are expected to occur every year within 600 Gpc (z ∼ 50) [7], most of which are missed by the GW networks at current sensitivities.…”

Advancements in cosmology through next-generation ground-based gravitational wave observatories will bring in a paradigm shift. We explore the pivotal role that gravitational-wave standard sirens will play in inferring cosmological parameters with next-generation observatories, not only achieving exquisite precision but also opening up unprecedented redshifts. We examine the merits and the systematic biases involved in gravitational-wave standard sirens utilizing binary black holes, binary neutron stars, and neutron star-black hole mergers. Further, we estimate the precision of bright sirens, golden dark sirens, and spectral sirens for these binary coalescences and compare the abilities of various next-generation observatories (\asharp, Cosmic Explorer, Einstein Telescope, and their possible networks). When combining different sirens, we find sub-percent precision over more than 10 billion years of cosmic evolution for the Hubble expansion rate $H(z)$.  This work presents a broad view of opportunities to precisely measure the cosmic expansion rate, decipher the elusive dark energy and dark matter, and potentially discover new physics in the uncharted Universe with next-generation gravitational-wave detectors.
