2005A&A...444L..37S Identification of 8 INTEGRAL hard X-ray sources with Chandra S. Sazonov, E. Churazov, M. Revnivtsev, A. Vikhlinin and R. Sunyaev Received 29 August 2005 / Accepted 22 October 2005 We report the results of identification of 8 hard X-ray sources discovered by the INTEGRAL observatory during the ongoing all-sky survey. These sources have been observed by Chandra. In 6 cases a bright X-ray source was found within the INTEGRAL localization region, which permitted to unambiguously identify 5 of the objects with nearby galaxies, implying that they have an active galactic nucleus (AGN), whereas one source is likely an X-ray binary in LMC. 4 of the 5 newly discovered AGNs have measured redshifts in the range 0.025-0.055. The X-ray spectra reveal the presence of significant amounts of absorbing gas ( N_H_ in the range 10^22^-10^24^ cm^-2^) in all 5 AGNs, demonstrating that INTEGRAL is starting to fill in the sample of nearby obscured AGNs. Key words: surveys, galaxies: Seyfert, X-rays: general
