Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XIV. Long-duration High-cadence Reverberation Mapping Results for 11 PG Quasars
We report the results of a long-duration high-cadence reverberation mapping campaign of a second batch of 11 PG quasars using the 2.2 m telescope at the Calar Alto Observatory. This follows a similar earlier study of another sample of 15 objects reported by C. Hu et al. (2021). Among the 11 PG quasa...

| description | We report the results of a long-duration high-cadence reverberation mapping campaign of a second batch of 11 PG quasars using the 2.2 m telescope at the Calar Alto Observatory. This follows a similar earlier study of another sample of 15 objects reported by C. Hu et al. (2021). Among the 11 PG quasars, eight objects have the H β time lags measured for the first time, while the other three objects were observed in previous campaigns but only had highly uncertain H β -lag measurements. Long-term light curves are presented of photometric V -band, spectroscopic 5100 Å continuum, and the H β emission line, lasting for ∼3–6 yr with a cadence of ∼6–14 days. Accurate H β time lags ranging from ∼20 to 150 days in the rest frame are obtained. The estimated virial masses of the central supermassive black holes range from ∼(3–300) × 10 ^7 M _⊙ . Combining these results with those reported in C. Hu et al. (2021), we now have 26 PG quasars, with representative properties, having reliable H β time-lag measurements from our long-duration high-cadence campaign. A tentative fit to the relation between the H β time lag and the continuum luminosity for these 26 objects gives a slope of 0.53. |
