Cosmology with AGN: can we use quasars as standard candles?
G. Risaliti, E. Lusso
The non-linear relation between X-ray and UV luminosity in quasars can be used to estimate their distance. Recently, we have shown that despite the large dispersion of the relation…
AGNfitter: A Bayesian MCMC approach to fitting spectral energy distributions of AGN
Gabriela Calistro-Rivera, Elisabeta Lusso, Joseph F. Hennawi +1
We present AGNfitter, a publicly available open-source algorithm implementing a fully Bayesian Markov Chain Monte Carlo method to fit the spectral energy distributions (SEDs) of ac…
Cosmological test with the QSO Hubble diagram
M. Lopez-Corredoira, F. Melia, E. Lusso +1
A Hubble diagram (HD) has recently been constructed in the redshift range 0<z<6.5 using a non-linear relation between the ultraviolet and X-ray luminosities of QSOs. The Type Ia SN…
The tight relation between X-ray and ultraviolet luminosity of quasars
E. Lusso, G. Risaliti
The observed relation between the soft X-ray and the optical-ultraviolet emission in active galactic nuclei (AGN) is non-linear and it is usually parametrized as a dependence betwe…
