Query: Multiband Observations of the Quasar PKS 2326-502 during Active and
  Quiescent Gamma-Ray States in 2010-2012   Quasi-simultaneous observations of the Flat Spectrum Radio Quasar PKS
2326-502 were carried out in the gamma-ray, X-ray, UV, optical, near-infrared,
and radio bands. Thanks to these observations we are able to characterize the
spectral energy distribution of the source during two flaring and one quiescent
gamma-ray states. These data were used to constrain one-zone leptonic models of
the spectral energy distributions of each flare and investigate the physical
conditions giving rise to them. While modeling one flare only required changes
to the electron spectrum, the other flare needed changes in both the electron
spectrum and the size of the emitting region with respect to the quiescent
state. These results are consistent with an emerging pattern of two broad
classes of flaring states seen in blazars.
