Isolated AGNs NGC 5347, ESO 438-009, MCG-02-04-090, and J11366-6002: Swift and NuSTAR joined view

We present the spectral analysis with the Nuclear Spectroscopic Telescope Array (NuSTAR) of four isolated galaxies with active galactic nuclei selected from the 2MIG catalogue: NGC 5347, ESO 438-009, MCG-02-09-040, and IGR J11366-6002. We also used the Swift/Burst Alert Telescope (BAT) data up to similar to 150 keV for MCG 02-09-040, ESO 438-009, and IGR J11366-6002 as well as the Swift/XRT data in 0.3-10 keV energy band for NGC 5347, ESO 438-009, and IGR J11366-6002. All the sources appear to have the reflected spectrum component with different reflection fractions in addition to the primary power-law continuum. We found that power-law indices for these sources lie between 1.6 and 1.8. The spectra of two sources, NGC 5347 and MCG-02-09-040, show the FeK(alpha)emission line. For both of these sources, the FeK(alpha)lines have a significant value of EW similar to 1 keV. The X-ray spectrum of NGC 5347 is best fitted by a pure reflection model withE(cut) similar to 117keV and without the presence of any additional primary power-law component. We also found that the X-ray spectrum of MCG-02-09-040 shows the presence of heavy neutral obscuration ofN(H) similar to 10(24) cm(-2). However, this provides a non-physical value of reflection in the case with fitting by a simple reflection model. A more appropriate fit is obtained with adopting the physical Monte Carlo-based model as BNTorus. It allowed us to determine the absorption value ofN(H) similar to 1.04 x 10(24) cm(-2)and reasonable power-law index of Gamma approximate to 1.63. Results for MCG-02-09-040 are presented for the first time.
