We present preliminary estimates of redshift- independent source luminosities and the Hubble diagram for quasars in the redshift range 0.1 <~ z <~ 2.6.STAMPAenConference paper10.1017/S17439213160126552-s2.0-85021254772000456300300060https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/highly-accreting-quasars-a-tool-for-cosmology/97168C6DCF4930405962886512102F5C2017IAUS..324..245MFIS/05 - ASTRONOMIA E ASTROFISICA
