    • Shemmer, Ohad; Brandt, W. N.; Paolillo, Maurizio; Kaspi, Shai; Vignali, Cristian; Lira Teillery, Paulina; Schneider, Donald P. (IOP Publishing Ltd, 2017)
      We report on the second installment of an X-ray monitoring project of seven luminous radio-quiet quasars (RQQs). New Chandra observations of four of these, at 4.10 <= z <= 4.35, yield a total of six X-ray epochs per source, ...
    • Lira Teillery, Paulina; Botti, Ismael; Kaspi, Shai; Netzer, Hagai (Frontiers media SA, 2018)
      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 ...
    • Lira Teillery, Paulina; Kaspi, Shai; Netzer, Hagai; Botti, Ismael; Morrell, Nidia; Mejia-Restrepo, Julián; Sánchez-Sáez, Paula; Martínez-Palomera, Jorge; López, Paula (Institute of Physics Publishing, 2018)
      We present reverberation mapping (RM) results for 17 high-redshift, high-luminosity quasars with good-quality R-band and emission-line light curves. We are able to measure statistically significant lags for Lyα (11 objects), ...
