Stellar population properties for a sample of hard X-ray AGNs
L. Morelli, V. Calvi, N. Masetti +5
The aim of this paper is to study the stellar population of galaxies hosting an active galactic nucleus (AGN). We studied a sub-sample of hard X-ray emitting AGNs from the INTEGRAL…
Multiwavelength studies of hard X-ray selected sources
Pietro Parisi
Hard X-ray surveys like those provided by IBIS and BAT on board the INTEGRAL and Swift satellites list a significant number of sources which are unidentified and/or unclassified an…
Accurate classification of 28 objects detected in the 39 months Palermo Swift/BAT hard X-ray catalogue
P. Parisi, N. Masetti, E. Jiménez-Bailón +12
Through an optical campaign performed at 4 telescopes located in the northern and the southern hemispheres, plus archival data from two on-line sky surveys, we have obtained optica…
Searching for AGNs among unidentified INTEGRAL sources
E. Maiorano, R. Landi, J. B. Stephen +13
We report on a new method to identify Active Galactic Nuclei (AGN) among unidentified INTEGRAL sources. This method consists of cross-correlating unidentified sources listed in the…
New AGN classifications in the Swift/BAT All-Sky Hard X-ray Survey
Pietro Parisi
Through an optical campaign performed at the San Pedro Martir (Mexico) Telescope and using the 6dF archive (http://www.aao.gov.au/local/www/6df, Jones et al. 2004), we determine or…
Study of the Sextans dwarf spheroidal galaxy from the DART CaII triplet survey
G. Battaglia, E. Tolstoy, A. Helmi +4
We use VLT/FLAMES intermediate resolution (R~6500) spectra of individual red giant branch stars in the near-infrared CaII triplet (CaT) region to investigate the wide-area metallic…
Revealing the nature of unidentified INTEGRAL sources through optical spectroscopy: an overview
P. Parisi, N. Masetti
Thanks to the INTEGRAL satellite the way of looking at the hard X-ray sky above 20 keV has changed substantially. Through the unique imaging and spectroscopy capabilities of the IB…
Accurate classification of 17 AGNs detected with Swift/BAT
P. Parisi, N. Masetti, E. Jiménez-Bailón +16
Through an optical campaign performed at 5 telescopes located in the northern and the southern hemispheres, plus archival data from two on line sky surveys, we have obtained optica…
On the identification of the Fermi/LAT source 0FGL J2001.0+4352 with a BL Lac
L. Bassani, R. Landi, N. Masetti +3
We report on the identification of the gamma-ray source 0FGL J20001.0+4352 listed in the Fermi bright source catalogue. This object, which has an observed 1-100 GeV flux of (7.8 +/…
