Abstract:
We perform a systematic X-ray spectroscopic analysis of 57 local
luminous and ultraluminous infrared galaxy systems (containing 84
individual galaxies) observed with the Nuclear Spectroscopic Telescope
Array and/or Swift/BAT. Combining soft X-ray data obtained with
Chandra, XMM-Newton, Suzaku, and/or Swift/XRT, we identify 40 hard
(>10keV) X-ray-detected active galactic nuclei (AGNs) and constrain
their torus parameters with the X-ray clumpy torus model XCLUMPY.
Among the AGNs at z<0.03, for which sample biases are minimized, the
fraction of Compton-thick (NH≥1024cm-2) AGNs reaches
64-15+14% (6/9 sources) in late mergers, while it is 24-10+12%
(3/14 sources) in early mergers, consistent with the tendency reported
by Ricci+ (2017MNRAS.468.1273R 2017MNRAS.468.1273R). We find that the bolometric AGN
luminosities derived from the infrared data increase but the X-ray to
bolometric luminosity ratios decrease with merger stage. The
X-ray-weak AGNs in late mergers ubiquitously show massive outflows at
subparsec to kiloparsec scales. Among them, the most luminous AGNs
(Lbol,AGN∼1046erg/s) have relatively small column densities of
≲1023cm-2 and almost super-Eddington ratios (λEdd∼1.0).
Their torus covering factors (CT(22)∼0.6) are larger than those of
Swift/BAT-selected AGNs with similarly high Eddington ratios. These
results suggest a scenario where, in the final stage of mergers,
multiphase strong outflows are produced due to chaotic quasi-spherical
inflows, and the AGN becomes extremely X-ray weak and deeply buried
due to obscuration by inflowing and/or outflowing material.
Description:
For the 49 U/LIRG systems other than the eight systems mentioned in
Section 2.5 (NGC 1068, NGC 1275, NGC 1365, Mrk 266, NGC 6240, UGC2608,
NGC 5135, and NGC 7469), we analyzed all of the available data of
NuSTAR (Section 3.1), Chandra (Section 3.2), XMM-Newton (Section 3.3),
and Suzaku (Section 3.4) observed by 2020 April. We also analyzed
their Swift/XRT data when no other soft X-ray data were available and
utilized the Swift/BAT spectra in the 105 month catalog if detected
(Section 3.5). For the other eight systems, we reduced the same data
as used in their references (see Section 2.5) and obtained the count
rates in order to treat the results in a uniform manner for all
57 systems. A log of the X-ray observations of our sample is provided
in Table 3.
