S.; Uttley, P.; Villforth, C.; Weiss, Y.; Woo, J.-H.; Yan, H.; Young, S.; Zu, Y. (Institute of Physics Publishing, 2017)
      We present the results of an optical spectroscopic monitoring program targeting NGC 5548 as part of a larger multi-wavelength reverberation mapping campaign. The campaign spanned six months and achieved an almost daily ...
    • The origin of UV-optical variability in AGN and test of disc models: XMM-Newton and ground-based observations of NGC 4395 

      McHardy, I. M.; Connolly, S. D.; Peterson, B. M.; Bieryla, A.; Chand, H.; Elvis, M. S.; Emmanoulopoulos, D.; Falco, E.; Kaspi, S.; Latham, D.; Lira Teillery, Paulina; McCully, C.; Netzer, H.; Uemura, M. (Wiley, 2016)
      The origin of short timescale (weeks/months) variability of AGN, whether due to intrinsic disc variations or reprocessing of X-ray emission by a surrounding accretion disc, has been a puzzle for many years. However recently ...
    • X-ray/UV/optical variability of NGC 4593 with Swift: Reprocessing of X-rays by an extended reprocessor 

      McHardy, I. M.; Connolly, S. D.; Horne, K.; Cackett, E. M.; Gelbord, J.; Peterson, B. M.; Pahari, M.; Gehrels, N.; Goad, M.; Lira, P.; Arevalo, P.; Baldi, R. D.; Brandt, N.; Breedt, E.; Chand, H.; Dewangan, G.; Done, C.; Elvis, M.; Emmanoulopoulos, D.; Fausnaugh, M. M.; Kasp (Oxford University Press, 2018)
      © 2018 The Author(s). We report the results of intensive X-ray, UV, and optical monitoring of the Seyfert 1 galaxy NGC 4593 with Swift. There is no intrinsic flux-related spectral change in any variable component with small ...
