Constraining cosmological parameters with reverberation-measured AGN

Constraining cosmological parameters with reverberation-measured AGN

Mary Loli Martı́nez-Aldama

The Radius-Luminosity relation (RL) offers the possibility to estimate the distance to the AGN independently of the redshift, which is suitable for cosmological analysis. However, it seems that the accretion rate induces a departure on the RL relation, which after all can be corrected. In order to improve the previous corrections and get better cosmological results, it is explored the use of the width of the line (σrms,line), measured in the RMS spectrum as a velocity field for estimating the black hole mass. Also, it is used a new bolometric correction for the Eddington ratio estimation. It is not possible to get a better correction, therefore the previous correction is used to constrain the cosmological parameters.
