J/MNRAS/460/19      Update of INTEGRAL/IBIS AGN catalogue    (Malizia+, 2016)

The INTEGRAL/IBIS AGN catalogue: an update. Malizia A., Landi R., Molina M., Bassani L., Bazzano A., Bird A.J., Ubertini P. <Mon. Not. R. Astron. Soc., 460, 19-29 (2016)> =2016MNRAS.460...19M (SIMBAD/NED BibCode)
ADC_Keywords: Surveys ; Gamma rays ; Active gal. nuclei Keywords: catalogues - surveys - galaxies: active Abstract: In the most recent IBIS survey based on observations performed during the first 1000 orbits of INTEGRAL, are listed 363 high-energy emitters firmly associated with AGN, 107 of which are reported here for the first time. We have used X-ray data to image the IBIS 90 per cent error circle of all the AGN in the sample of 107, in order to obtain the correct X-ray counterparts, locate them with arcsec accuracy and therefore pinpoint the correct optical counterparts. This procedure has led to the optical and spectral characterization of the entire sample. This new set consists of 34 broad line or type 1 AGN, 47 narrow line or type 2 AGN, 18 blazars and 8 sources of unknown class. These eight sources have been associated with AGN from their positional coincidence with 2MASX/Radio/X-ray sources. Seven high-energy emitters have been included since they are considered to be good AGN candidates. Spectral analysis has been already performed on 55 objects and the results from the most recent and/or best statistical measurements have been collected. For the remaining 52 sources, we report the spectral analysis for the first time in this work. We have been able to obtain the full X-ray coverage of the sample making use of data from Swift/XRT, XMM-Newtonand NuSTAR. In addition to the spectral characterization of the entire sample, this analysis has enabled us to identify peculiar sources and by comparing different data sets, highlight flux variability in the 2-10keV and 20-40keV bands. Description: In this paper we present the X-ray and optical follow-up work on 107 new AGN recently detected by INTEGRAL. Luckily, we have been able to obtain full X-ray coverage of the entire sample making use of data from Swift/XRT, Newton-XMM and NuSTAR archives or through Swift/XRT follow up observations triggered by us.

Note (1): Notes as follows: f = already present in previous IBIS catalogues but only recently identified as active galactic nuclei and hence reported here as new INTEGRAL AGN i = two X-ray sources, 1 identified as a Sy 1.2 and 1 AGN candidate, are present in the IBIS error box e = new classification in Masetti et al. (in preparation) h = the blazar object is blended with a CV but Bassani et al. (2014A&A...561A.108B) have estimated that the 90 per cent hard X-ray fluxed comes from the AGN d = XMM data g = NuSTAR data
