Paulina Lira, Ismael Botti, Shai Kaspi, Hagai Netzer
TL;DR
This study conducts reverberation mapping on 17 high-redshift, high-luminosity quasars over a decade, revealing variability and establishing radius-luminosity relations for key emission lines, advancing understanding of quasar structure.
Contribution
It provides the first long-term reverberation mapping results for high-z, high-luminosity quasars, including new radius-luminosity relations for Ly_alpha and CIV lines.
Findings
Detected continuum and line variability in all quasars
Successfully measured emission line lags in several sources
Established radius-luminosity relations for Ly_alpha and CIV
Abstract
We present Reverberation Mapping results after monitoring a sample of 17 high-z, high-luminosity quasars for more than 10 years using photometric and spectroscopic capabilities. Continuum and line emission flux variability is observed in all quasars. Using cross-correlation analysis we successfully determine lags between the variations in the continuum and broad emission lines for several sources. Here we present a highlight of our results and the determined radius--luminosity relations for Ly_alpha and CIV.
