Optical Continuum and Emission-Line Variability of Seyfert 1 Galaxies
Bradley M. Peterson,Ignaz Wanders,Ignaz Wanders,R. Bertram,R. Bertram,James F. Hunley,Richard W. Pogge,R. Mark Wagner,R. Mark Wagner +8 more
TL;DR: In this paper, the authors used cross-correlation analysis to derive the sizes of the broad Hβ-emitting regions based on emission-line time delays, or lags.

Optical Continuum and Emission-Line Variability of Seyfert 1 Galaxies
Bradley M. Peterson,Ignaz Wanders,Ignaz Wanders,R. Bertram,R. Bertram,James F. Hunley,Richard W. Pogge,R. Mark Wagner,R. Mark Wagner +8 more
TL;DR: In this paper, the authors present the light curves obtained during an eight-year program of optical spectroscopic monitoring of nine Seyfert 1 galaxies: 3C 120, Akn 120, Mrk 79, MRK 79, RMK 110, MRKS 335, MRKK 509, MRk 590, MRKN 704, MRKT 704 and MRK 817.

TL;DR: In this paper, the results of 3 yr of ground-based observations of the Seyfert 1 galaxy NGC 5548 were combined with previously reported data, yielding optical continuum and broad-line Hβ light curves for a total of 8 yr.

TL;DR: In this article, the authors present the results of three years of ground-based observations of the Seyfert 1 galaxy NGC 5548, which combined with previously reported data, yield optical continuum and broad-line H-beta light curves for a total of eight years.
