The SOUX AGN sample: Optical/UV/X-ray SEDs and the nature of the disc

Jake A. J. Mitchell, Chris Done, Martin J. Ward +4

We use the SOUX sample of 700 AGN to form average optical-UV-X-rays SEDs on a 2D grid of and . We compare these with the predictions of a new AGN…

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…

The Extreme Super-Eddington NLS1 RX J0134.2-4258 -- II. A Weak-Line Seyfert Linking to the Weak-Line Quasar

Chichuan Jin, Chris Done, Martin Ward +3

RX J0134.2-4258 is one of the most super-Eddington narrow-line Seyfert 1 (NLS1) galaxies, on which we conducted a monitoring campaign from radio to X-rays. In this paper, we presen…

Multi-wavelength Campaign on the Super-Eddington NLS1 RX J0134.2-4258 -- I. Peculiar X-ray Spectra and Variability

Chichuan Jin, Chris Done, Martin Ward +3

We have conducted a new long-term multi-wavelength campaign on one of the most super- Eddington narrow-line Seyfert 1s (NLS1s) known, namely RX J0134.2-4258. In this first paper, w…
