The first spectroscopic dust reverberation programme on active galactic nuclei: the torus in NGC 5548
H. Landt, M. J. Ward, D. Kynoch +16
We have recently initiated the first spectroscopic dust reverberation programme on active galactic nuclei (AGN) in the near-infrared. Spectroscopy enables measurement of dust prope…
The relativistic jet of the -ray emitting narrow-line Seyfert 1 galaxy PKS J12220413
Daniel Kynoch, Hermine Landt, Martin J. Ward +5
We present a multi-frequency study of PKS J12220413 (4C04.42), currently the highest redshift -ray emitting narrow-line Seyfert 1 (-NLS1). We assemble a broad spectral…
The 'Big Dipper': The nature of the extreme variability of the AGN SDSS J2232-0806
Daniel Kynoch, Martin J. Ward, Andy Lawrence +3
SDSS J2232-0806 (the 'Big Dipper') has been identified as a 'slow-blue nuclear hypervariable': a galaxy with no previously known active nucleus, blue colours and large-amplitude br…
The relativistic jet of the gamma-ray emitting narrow-line Seyfert 1 galaxy 1H 0323+342
Daniel Kynoch, Hermine Landt, Martin J. Ward +7
The detection of several radio-loud narrow-line Seyfert 1 (NLS1) galaxies by the Fermi Gamma-Ray Space Telescope hints at the existence of a rare, new class of gamma-ray emitting a…
