We present a multiwavelength study of the environment of the unidentified X-ray/γ-ray sources IGR J18027–1455 and IGR J21247 + 5058, recently discovered by the IBIS/ISGRI instrument, onboard the INTEGRAL satellite. The main properties of the sources found inside their position error circles, give us clues about the nature of these high-energy sources. 
Multi-wavelength properties of the high-energy bright Seyfert 1 galaxy IGR J18027-1455
A new sample of hard X-ray sources in the Galactic Plane is being revealed by the regular observations performed by the INTEGRAL satellite. The full characterization of these sources is mandatory toExpand
Unveiling the nature of INTEGRAL sources through optical spectroscopy
Since its launch on October 2002 the INTEGRAL satellite is performing an deep survey of the hard X-ray sky with unprecedented sensitivity and positional accuracy. This allowed pinpointing, throughExpand
Unveiling the nature of INTEGRAL objects through optical spectroscopy. II. The nature of four uniden
We present the results of our optical spectrophotometric campaign ongoing at the Astronomical Observatory of Bologna in Loiano (Italy) on hard X-ray sources detected by INTEGRAL. We observed spec-Expand
Coronal temperatures of the AGN ESO 103−035 and IGR 2124.7+5058 from NuSTAR observations
We present measurements of the coronae of two AGN from hard X-ray observations made with NuSTAR: ESO 103-035, a moderately to highly obscured source with significant reflection; and IGR 2124.7+5058,Expand


Structure of the X-Ray Emission from the Jet of 3C 273
We present images from five observations of the quasar 3C 273 with the Chandra X-Ray Observatory. The jet has at least four distinct features that are not resolved in previous observations. The firstExpand
The First IBIS/ISGRI Soft Gamma-Ray Galactic Plane Survey Catalog*
We report the first high-energy survey catalog obtained with the IBIS gamma-ray imager on board INTEGRAL. The analysis has been performed on the first-year Core Program ISGRI data comprising bothExpand
X-Ray Detection of the Inner Jet in the Radio Galaxy M84
During the course of an investigation of the interaction of the radio galaxy M84 and its ambient cluster gas, we found excess X-ray emission aligned with the northern radio jet. The emission extendsExpand
X-ray Emission Processes in Radio Jets
The emission processes responsible for the observed X-rays from radio jets are commonly believed to be nonthermal, but in any particular case, it is unclear if synchrotron emission or one or moreExpand
The INTEGRAL mission
The ESA observatory INTEGRAL (International Gamma-Ray Astrophysics Laboratory) is dedicated to the fine spectroscopy (2.5 keV FWHM @ 1 MeV) and fine imaging (angular resolution: 12 arcmin FWHM) ofExpand
The sky behind our galaxy as seen by IBIS on INTEGRAL
During the Core Programme, INTEGRAL has surveyed a large portion of the sky (around 9000 square degrees); although INTEGRAL is not optimized for extra-galactic studies its observations haveExpand
The NRAO VLA Sky Survey
?????The NRAO VLA Sky Survey (NVSS) covers the sky north of J2000.0 ? = -40? (82% of the celestial sphere) at 1.4 GHz. The principal data products are (1) a set of 2326 4? ? 4? continuum cubes withExpand
