Chandra Follow-up Observations of Swift-BAT-selected AGNs II
  We present the combined Chandra and Swift-BAT spectral analysis of nine
low-redshift (z <= 0.10), candidate heavily obscured active galactic nuclei
(AGN) selected from the Swift-BAT 150-month catalog. We located soft (1-10 keV)
X-ray counterparts to these BAT sources and joint fit their spectra with
physically motivated models.The spectral analysis in the 1-150 keV energy band
determined that all sources are obscured, with a line-of-sight column density
NH >= 10^22 cm^-2 at a 90% confidence level. Four of these sources show
significant obscuration with NH >= 10^23 cm^-2 and two additional sources are
candidate Compton-thick Active Galactic Nuclei (CT-AGNs) with NH >= 10^24
cm^-2.These two sources, 2MASX J02051994-0233055 and IRAS 11058-1131, are the
latest addition to the previous 3 CT-AGN candidates found using our strategy
for soft X-ray follow-up of BAT sources. In here we present the results of our
methodology so far, and analyze the effectiveness of applying different
selection criteria to discover CT-AGN in the local Universe. Our selection
criteria has a ~20% success rate of discovering heavily obscured AGN whose CT
nature is confirmed by follow-up NuSTAR observations. This is much higher than
the ~5% found in blind surveys.
