Reverberation mapping of distant quasars: Time lag determination using different methods
Original language description
By applying different statistically robust methods, we analyze the time lag between the continuum and ionized line-emission (Mg II line) light curves for the distant bright quasar CTS C30.10 (redshift z similar to 0.9). The data were obtained by the 10-meter South African Large Telescope (SALT) telescope in South Africa. In detail, we demonstrate the application of several methods using the interpolated cross-correlation function (ICCF), discrete correlation function (DCF), z-transformed discrete correlation function (zDCF), von Neumann estimator, and the JAVELIN code package. In particular, we discuss the uncertainties of these methods. In conclusion, we find that the quasar lies on the broad-line region (BLR) size-monochromatic luminosity power-law scaling, RBLR proportional to L51001/2, which was already confirmed for low-redshift sources. In case, the BLR size-luminosity relation holds for other distant sources, quasars could be used to probe cosmological models as “standard candles” complementary to supernovae Ia.
