The Cosmological Parameters for the redshift range from 5.6 to 7.0 openParPart 1closePar

With the paper A Hubble Diagram for Quasars Risaliti and Lusso (2015)established quasars as a kind of standard candles to measure cosmologicalparameters. This method is of utmost importance as it allows to measure thecosmological parameters for different redshift ranges and to test for anevolution of the parameters over cosmological time. We propose to observe 131quasars at a redshift higher than 5.6, i.e. nearly all known such quasars(Banados et al., 2016) not yet observed in Xray. The aim is to measure thecosmological parameters with high precession in the redshift range from 5.6 to7.0 for the first time. This redshift rang is not accessible with any othermethod, e.g. supernovae, clusters of galaxies, microwave back ground or baryon acoustic oscillations. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
