Probing varvecΛCDM-mimicking varvecf(Q) gravity model using gravitational waves from compact binary coalescences

Abstract
The direct detection of gravitational waves (GWs) is a very significant achievement in the history of physics and has opened a new window to probe the possible deviations of physics from that of general relativity (GR). In this work, we forecast constraints on the free parameter of an f(Q) gravity model that mimics a ΛCDM background at the level of cosmic expansion. We consider modified gravitational wave signals from inspiraling of compact binary systems such as binary black holes (BBH), binary neutron stars (BNS) and black hole neutron star binary (BBHNS) systems in the context of the f(Q) gravity model and perform parameter estimation for two future third-generation ground-based GW detectors, namely Einstein Telescope (ET) and Cosmic explorer (CE), respectively. Our results show that both detectors can give tight constraints on the model parameter up to a significantly high redshift. These results show the potential of future GW observations to probe the deviations of the nature of GWs from that of GR within the framework of f(Q) gravity.
