Query: Suzaku Follow-up of Heavily Obscured Active Galactic Nuclei Detected in
  Swift/BAT Survey: NGC 1106, UGC 03752, and NGC 2788A   We present the broadband (0.5-100 keV) spectra of three heavily obscured
Active Galactic Nuclei (AGNs), NGC 1106, UGC 03752, and NGC 2788A, observed
with Suzaku and Swift/Burst Alert Telescope (BAT). The targets are selected
from the Swift/BAT 70-month catalog on the basis of high hardness ratio between
above and below 10 keV, and their X-ray spectra are reported here for the first
time. We apply three models, a conventional model utilizing an analytic
reflection code and two Monte-Carlo based torus models with a doughnut-like
geometry (MYTorus) and with a nearly spherical geometry (Ikeda torus). The
three models can successfully reproduce the spectra, while the Ikeda torus
model gives better description than the MYTorus model in all targets. We
identify that NGC 1106 and NGC 2788A as Compton-thick AGNs. We point out that
the common presence of unabsorbed reflection components below 7.1 keV in
obscured AGNs, as observed from UGC 03752, is evidence for clumpy tori. This
implies that detailed studies utilizing clumpy torus models are required to
reach correct interpretation of the X-ray spectra of AGNs.
