We present results of our analysis of NuSTAR data of the luminous infrared
galaxy Mrk 266, which contains two nuclei, SW and NE, resolved in previous
Chandra imaging. Combining with the Chandra data, we intepret the hard X-ray
spectrum obtained from a NuSTAR observation as resulting from steeply rising
flux from a Compton-thick AGN in the SW nucleus which is very faint in the
Chandra band, confirming the previous claim of Mazzarella et al. (2012). This
hard X-ray component is dominated by reflection, and its intrinsic 2-10 keV
luminosity is likely to be ~1e43 erg/s. Although it is bright in soft X-ray,
only moderately absorbed NE nucleus has a 2-10 keV luminosity of 4e41 erg/s,
placing it in the low-luminosity AGN class. These results have implications for
understanding the detectability and duty cycles of emission from dual AGN in
heavily obscured mergers.
