Mapping the nuclear environments of extreme coronal line emitting galaxies

Daniel Kynoch, Or Graur, Peter Clark +30

Extreme coronal line emitters (ECLEs) are a rare class of galactic nuclei exhibiting unusually strong high-ionisation forbidden emission lines, and several ECLEs have been linked t…

Intensive X-ray/UVOIR continuum reverberation mapping of the Seyfert AGN MCG+08-11-11

D. Kynoch, I. M. McHardy, E. M. Cackett +11

We present results from intensive (x3 daily), three-month-long X-ray, UV and optical monitoring of the bright Seyfert active galactic nucleus (AGN) MCG+08-11-11 with Swift, support…

AGN STORM 2. XI. Spectroscopic reverberation mapping of the hot dust in Mrk 817

Hermine Landt, Benjamin D. Boizelle, Michael S. Brotherton +41

The AGN Space Telescope and Optical Reverberation Mapping 2 (STORM 2) campaign targeted Mrk 817 with intensive multi-wavelength monitoring and found its soft X-ray emission to be s…

Testing disc reprocessing models for AGN optical variability by comparison of X-ray and optical power spectra of NGC 4395

Max Beard, Ian McHardy, Keith Horne +11

It is generally thought that AGN optical variability is produced, at least in part, by reprocessing of central X-rays by a surrounding accretion disc, resulting in wavelength-depen…

AGN STORM 2: IX. Studying the Dynamics of the Ionized Obscurer in Mrk 817 with High-resolution X-ray Spectroscopy

Fatima Zaidouni, Erin Kara, Peter Kosec +45

We present the results of the XMM-Newton and NuSTAR observations taken as part of the ongoing, intensive multi-wavelength monitoring program of the Seyfert 1 galaxy Mrk 817 by the…

The first spectroscopic IR reverberation programme on Mrk 509

J. A. J. Mitchell, M. J. Ward, D. Kynoch +12

Near IR spectroscopic reverberation of Active Galactic Nuclei (AGN) potentially allows the infrared (IR) broad line region (BLR) to be reverberated alongside the disc and dust cont…
