      We present results from a 15 month campaign of high-cadence (∼3 days) mid-infrared Spitzer and optical (B and V) monitoring of the Seyfert 1 galaxy NGC 6418, with the objective of determining the characteristic size of the ...
    • The first spectroscopic dust reverberation programme on active galactic nuclei : the torus in NGC 5548 

      Landt, Hermine; Ward, Martin John; Kynoch, Daniel; Packham, Christopher; Ferland, Gary J.; Lawrence, Andy; Pott, Jörg-Uwe; Esser, Johannes; Horne, Keith; Starkey, David A.; Malhotra, Deepak; Fausnaugh, Michael; Peterson, Bradley M.; Wilman, Richard J.; Riffel, Rogemar André; Storchi-Bergmann, Thaisa; Barth, Aaron J.; Villforth, Carolin; Winkler, Hartmut (2019) [Journal article]
      We have recently initiated the first spectroscopic dust reverberation programme on active galactic nuclei in the near-infrared. Spectroscopy enables measurement of dust properties, such as flux, temperature, and covering ...
