Double-peaked profiles: ubiquitous signatures of disks in the Broad Emission Lines of Active Galactic Nuclei
Thaisa Storchi-Bergmann, Jaderson S. Schimoia, Bradley M. Peterson +4
Broad (~10,000 km/s), double-peaked emission-line profiles of Balmer lines emitted by active galactic nuclei (AGN) are thought to originate in the outer parts of an accretion disk…
Space Telescope and Optical Reverberation Mapping Project VI: reverberating Disk Models for NGC 5548
D. Starkey, Keith Horne, M. M. Fausnaugh +90
We conduct a multiwavelength continuum variability study of the Seyfert 1 galaxy NGC 5548 to investigate the temperature structure of its accretion disk. The 19 overlapping continu…
On the black hole mass of the gamma-ray emitting narrow-line Seyfert 1 galaxy 1H 0323+342
H. Landt, M. J. Ward, M. Balokovic +6
Narrow-line Seyfert 1 galaxies have been identified by the Fermi Gamma-Ray Space Telescope as a rare class of gamma-ray emitting active galactic nuclei (AGN). The lowest-redshift c…
Space Telescope and Optical Reverberation Mapping Project. IV. Anomalous behavior of the broad ultraviolet emission lines in NGC 5548
M. R. Goad, K. T. Korista, G. De Rosa +99
During an intensive Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS) UV monitoring campaign of the Seyfert~1 galaxy NGC 5548 performed from 2014 February to July, the…
