Is the Hubble diagram of quasars in tension with concordance cosmology?
Recently, Risaliti and Lusso [Nat. Astron. 3, 272 (2019)] reported new measurements of the expansion rate of the Universe by constructing the Hubble diagram of 1598 quasars in the redshift range 0.5

We conclude claiming that the quasars data cannot yet be seen as a reliable cosmological tool since they cannot even state the universe experienced an accelerated expansion phase.</description><identifier>ISSN: 2470-0010</identifier><identifier>EISSN: 2470-0029</identifier><identifier>DOI: 10.1103/PhysRevD.101.043502</identifier><language>eng</language><publisher>College Park: American Physical Society</publisher><subject>Acceleration ; Big Bang theory ; Cosmology ; Dark energy ; Equations of state ; Hubble diagram ; Quasars ; Red shift ; Universe</subject><ispartof>Physical review.
