报告题目：Constraining cosmological parameters from FRB-GW association events without redshifts

报告人：诸葛佳明（美国内华达大学）

报告摘要：The merger of binary compact objects leads to some of the most energetic events in the universe. Early research suggested that these mergers may be a progenitor of Fast Radio Bursts (FRBs). Given their short durations and cosmological distances, the Dispersion Measure (DM)–redshift ($z$) relation of FRBs serves as a powerful tool for constraining cosmological parameters and probing the missing baryons. However, localizing FRBs to obtain precise redshifts remains challenging. To address this, the luminosity distance derived from Gravitational Waves (GWs) can act as a "standard siren," providing an alternative way to constrain cosmology. In this talk, I will present our recent work utilizing the latest corrected FRB probability density functions and the DM–luminosity distance relation. Using Bayesian inference and marginalization, we investigate the potential of these associations to constrain both cosmological parameters and host galaxy properties.
