Modelling the variable emission states of -ray emitting Narrow-Line Seyfert 1 galaxies
Anna Luashvili, Catherine Boisson, Andreas Zech +2
-ray-emitting narrow-line Seyfert 1 galaxies (-NLS1) constitute an intriguing small population of Active Galactic Nuclei with -ray emission resembling low power flat-spect…
AGN STORM 2: II. Ultraviolet Observations of Mrk817 with the Cosmic Origins Spectrograph on the Hubble Space Telescope
Y. Homayouni, Gisella De Rosa, Rachel Plesha +62
We present reverberation mapping measurements for the prominent ultraviolet broad emission lines of the active galactic nucleus Mrk817 using 165 spectra obtained with the Cosmic Or…
The SOUX AGN Sample: SDSS-XMM-Newton Optical, Ultraviolet and X-ray selected active galactic nuclei spanning a wide range of parameter space -- Sample definition
Daniel Kynoch, Jake A. J. Mitchell, Martin J. Ward +3
We assemble a sample of 696 type 1 AGN up to a redshift of , all of which have an SDSS spectrum containing at least one broad emission line (H , H or Mg II) and an XM…
Multiple locations of near-infrared coronal lines in NGC 5548
Daniel Kynoch, Hermine Landt, Maryam Dehghanian +2
We present the first intensive study of the variability of the near-infrared coronal lines in an active galactic nucleus (AGN). We use data from a one-year long spectroscopic monit…
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…
