Intensive disc-reverberation mapping of Fairall 9: 1st year of Swift &
  LCO monitoring
  We present results of time-series analysis of the first year of the Fairall 9
intensive disc-reverberation campaign. We used Swift and the Las Cumbres
Observatory global telescope network to continuously monitor Fairall 9 from
X-rays to near-infrared at a daily to sub-daily cadence. The cross-correlation
function between bands provides evidence for a lag spectrum consistent with the
$\tau\propto\lambda^{4/3}$ scaling expected for an optically thick,
geometrically thin blackbody accretion disc. Decomposing the flux into constant
and variable components, the variable component's spectral energy distribution
is slightly steeper than the standard accretion disc prediction. We find
evidence at the Balmer edge in both the lag and flux spectra for an additional
bound-free continuum contribution that may arise from reprocessing in the
broad-line region. The inferred driving light curve suggests two distinct
components, a rapidly variable ($<4$ days) component arising from X-ray
reprocessing, and a more slowly varying ($>100$ days) component with an
opposite lag to the reverberation signal.
