Abstract:
We present measurements of broad emission lines and virial estimates
of supermassive black hole masses (MBH) for a large sample of
ultrahard X-ray-selected active galactic nuclei (AGNs) as part of the
second data release of the BAT AGN Spectroscopic Survey (BASS/DR2).
Our catalog includes MBH estimates for a total of 689 AGNs,
determined from the Hα, Hβ, MgIIλ2798, and/or
CIVλ1549 broad emission lines. The core sample includes a total
of 512 AGNs drawn from the 70 month Swift/BAT all-sky catalog. We also
provide measurements for 177 additional AGNs that are drawn from
deeper Swift/BAT survey data. We study the links between MBH estimates
and line-of-sight obscuration measured from X-ray spectral analysis.
We find that broad Hα emission lines in obscured AGNs
(log(NH/cm-2)>22.0) are on average a factor of 8.0-2.4+4.1
weaker relative to ultrahard X-ray emission and about 35-12+7%
narrower than those in unobscured sources (i.e., log(NH/cm-2)<21.5).
This indicates that the innermost part of the broad-line region is
preferentially absorbed. Consequently, current single-epoch MBH
prescriptions result in severely underestimated (>1dex) masses for
Type 1.9 sources (AGNs with broad Hα but no broad Hβ)
and/or sources with log(NH/cm-2)≳22.0. We provide simple
multiplicative corrections for the observed luminosity and width of
the broad Hα component (L[bHα] and FWHM[bHα]) in
such sources to account for this effect and to (partially) remedy MBH
estimates for Type 1.9 objects. As a key ingredient of BASS/DR2, our
work provides the community with the data needed to further study
powerful AGNs in the low-redshift universe.
