Accurate classification of 75 counterparts of objects detected in the 54 month Palermo Swift/BAT hard X-ray catalogue
P. Parisi, N. Masetti, A. F. Rojas +10
Through an optical campaign performed at 4 telescopes located in the northern and the southern hemispheres, we have obtained optical spectroscopy for 75 counterparts of unclassifie…
BL Lacertae identifications in a ROSAT-selected sample of Fermi unidentified objects
N. Masetti, B. Sbarufatti, P. Parisi +15
The optical spectroscopic followup of 27 sources belonging to a sample of 30 high-energy objects selected by positionally cross correlating the first Fermi/LAT Catalog and the ROSA…
Symbiotic Stars in OGLE Data I. Large Magellanic Cloud Systems
R. Angeloni, C. E. Ferreira Lopes, N. Masetti +10
Symbiotic stars are long-orbital-period interacting-binaries characterized by extended emission over the whole electromagnetic range and by complex photometric and spectroscopic va…
Unveiling the nature of INTEGRAL objects through optical spectroscopy. X. A new multi-year, multi-observatory campaign
N. Masetti, P. Parisi, E. Palazzi +18
Within the framework of our program (running since 2004) of identification of hard X-ray INTEGRAL sources through optical spectroscopy, we present the results concerning the nature…
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…
Identification of newly-discovered sources belonging to the 4th IBIS catalog and to the 54 months Palermo Swift/BAT catalog
P. Parisi, N. Masetti, A. F. Rojas +17
The most recent all-sky surveys performed with the INTEGRAL and SWIFT satellites allowed the detection of more than 1500 sources in hard X-rays above 20 keV. About one quarter of t…
