Chandra identification of two AGN discovered by INTEGRAL

Here, we report on observations of two hard X-ray sources that were originally discovered with the INTEGRAL satellite: IGR J04059+5416 and IGR J08297-4250.We use the Chandra X-ray Observatory to localize the sources and then archival near-IR images to identify the counterparts. Both sources have counterparts in the catalogue of extended 2 Micron All-Sky Survey sources, and the counterpart to IGR J04059+5416 has been previously identified as a galaxy. Thus, we place IGR J04059+5416 in the class of active galactic nuclei (AGN), and we suggest that IGR J08297-4250 is also an AGN. If this identification is correct, the near-IR images suggest that the host galaxy of IGR J08297-4250 may be merging with a smaller nearby galaxy. For IGR J04059+5416, the 0.3-86 keV spectrum from Chandra and INTEGRAL is consistent with an absorbed power-law with a column density of N_H = (3.1^+2.0 _-1.5) × 10²² cm^-2 and a photon index of Γ = 1.4 ± 0.7, and we suggest that it is a Seyfert galaxy. For IGR J08297-4250, the photon index is similar, Γ = 1.5 ± 0.8, but the source is highly absorbed (N_H = (6.1^+10.1 _-4.3) × 10²³ cm^-2).
