Observational constraints on interacting dark energy models with multiple measurements of quasars

Dark energy and dark matter, two subjects of basic physics, have received a lot of attention in the 21st century. From theobservational point of view, the interaction between dark energy and dark matter can significantly affect cosmological dis-tances. This gives rise to the possibility of indirectly detecting such interaction through high-redshift cosmological probes.Theoretically, the introduction of interaction between dark energy and dark matter can assist in alleviating the coincidenceproblem of the standard cosmological model (Lambda CDM model). Furthermore, this can provide a new method of studying theproperties of dark matter particles. In this paper, based on the latest observations of multiple measurements of quasars (X-ray+UV quasars acting as standard candles, compact radio quasars acting as standard rulers) covering the redshift range of0.04更多
