DESCRIPTION:Speakers: Mary Loli Martínez-Aldama (CFT)\nQuasars have been 
 proposed as a new class of standard candles such as\nSupernovae\, their la
 rge redshift range and high luminosities make them\nexcellent candidates. 
 Reverberation mapping (RM) method offers to\nestimate the distance to the 
 source from the time delay measurement of\nthe emission lines with respect
  to the continuum\, since the time delay\ndepends on the absolute luminosi
 ty of the source. This radius-luminosity\n(RL) relation showed a low scatt
 er and was proposed to use for the\ncosmological purposes. However\, in th
 e recent years the increase of the\nstudied sample\, and in particular the
  inclusion of highly accreting QSO\nhas increased the dispersion in the RL
  relation\, with many objects\nshowing time delays shorter than the expect
 ed. Using Hb RM\nmeasurements for 117 sources with a 0.2\n\nhttps://events
