A wind-based unification model for NGC 5548: spectral holidays, non-disk emission, and implications for changing-look quasars
M. Dehghanian, G. J. Ferland, B. M. Peterson +9
The 180-day Space Telescope and Optical Reverberation Mapping campaign on NGC 5548 discovered an anomalous period, the broad-line region (BLR) holiday, in which the emission lines…
Quantifying the impact of variable BLR diffuse continuum contributions on measured continuum inter-band delays
K. T. Korista, M. R. Goad
We investigate the contribution of reprocessed continuum emission (1000A - 10,000A) originating in broad line region (BLR) gas, the diffuse continuum (DC), to the wavelength-depend…
Space Telescope and Optical Reverberation Mapping Project. VIII. Time Variability of Emission and Absorption in NGC 5548 Based on Modeling the Ultraviolet Spectrum
G. A. Kriss, G. De Rosa, J. Ely +164
We model the ultraviolet spectra of the Seyfert 1 galaxy NGC~5548 obtained with the Hubble Space Telescope during the 6-month reverberation-mapping campaign in 2014. Our model of t…
Anomalous behaviour of the UV-optical continuum bands in NGC 5548
M. R. Goad, C. Knigge, K. T. Korista +8
During the 2014 HST/Swift and ground-based multi-wavelength monitoring campaign of NGC 5548 (AGN STORM), the UV-optical broad emission lines exhibited anomalous, decorrelated behav…
