“…compatible with the value on the line of sight obtained from the LAB survey (Kalberla et al 2005). The extrapolated 20-40 keV flux is compatible with the flux measured by IBIS (Bird et al 2010), which further strengthens the associations of the X-ray source and the IBIS one. The high galactic latitude, the radio detection, and the brightness in all IR/optical and UV bands as well as the detection at soft and hard X-ray energies argue in favour of the source being an AGN.…”

“…The power-law slope is, however, very poorly constrained and very soft (Γ = 4.3 +3.9 −2.4 ) for an AGN, but this model also indicates a high level of intrinsic absorption. In this case the extrapolated 20-40 keV flux is incompatible with the IBIS flux reported in Bird et al (2010). However, freezing the photon index to a more common value of 1.8 leads to a 20-40 keV flux just slightly below what is reported in the 4th IBIS catalogue.…”

“…This source is one of the new IGRs reported in the most recent version of the IBIS catalogue (Bird et al 2010), for which inspection of the Swift archives shows an observation aimed at a Swift object. Although the coordinates of Swift J0208.5−1738 and that of the IGR sources indicate an offset of about 5 , both objects have error boxes that render their association likely.…”

The various IBIS/ISGRI catalogues contain a large population of hard X-ray sources whose nature is still unknown. Even if the >20 keV positional uncertainty provided by ISGRI is unprecedented, it is still too large to pinpoint the counterpart at other wavelengths, which is the only secure way of obtaining a source identification. We continue the work of trying to reveal the nature of these hard X-ray sources, starting with analysis of X-ray data collected via focusing X-ray telescopes, in order to obtain arcsec accurate X-ray positions. We can then identify counterparts at infrared and optical wavelengths and try to unveil the nature of the sources. We analysed data from observations of 13 INTEGRAL sources made with the Swift satellite. The X-ray images obtained by the X-Ray Telescope instrument allowed us to find possible counterparts to the IGR sources with a positional accuracy of a few arcsec. We then browsed the online catalogues (e.g., NED, SIMBAD, 2MASS, 2MASX, USNO B1.0) to search for counterparts at other wavelengths. We also made use of the X-ray spectral parameters in trying to identify the nature of those objects. For the 13 objects, we found possible counterparts at X-ray energies and identified the IR/optical and/or UV counterparts as seen with Swift/UVOT. We also discuss the likelihood of association of the X-ray and INTEGRAL source in each case. We confirm the previously proposed classification of IGR J02524-0829 (Sey 2 AGN), J08023-6954 (RS CVn star), and J11457-1827 (Sey 1 AGN). For 7 of these sources we give the first identification of their nature: IGR J02086-1742, J12060+3818, J12070+2535, J13042-1020, and J13412+3022 are AGN, and J14488-5942 is a probable X-ray binary. For J03184-0014, although we question the association of the IGR and Swift sources, we classify the latter as an AGN. We suggest that IGR J15283-4443 is a Galactic source, but we cannot classify the source further. Finally, we question the association of IGR J11457-1827 and J23130+8608 with the X-ray sources we found, and go on to question the genuineness of the former IGR source.

“…Sidoli et al, 2009b, and references therein). Bird et al (2010a) and Zurita Heras and Chaty (2009a) determined the best orbital period of the source at 30±0.1 d. Zurita Heras and Chaty (2009a) also found that most of the discovered outbursts took place close to the periastron passage, and that the source usually remains relatively bright in X-rays for about ∼6 d around this orbital phase. Outbursts in several periastron passages were missing.…”

High-mass X-ray binaries are fundamental in the study of stellar evolution, nucleosynthesis, structure and evolution of galaxies and accretion processes. Hard X-rays observations by INTEGRAL and Swift have broadened significantly our understanding in particular for the super-giant systems in the Milky Way, which number has increased by almost a factor of three. INTEGRAL played a crucial role in the discovery, study and understanding of heavily obscured systems and of fast X-ray transients. Most super-giant systems can now be classified in three categories: classical/obscured, eccentric and fast transient.The classical systems feature low eccentricity and variability factor of ∼ 10 3 , mostly driven by hydrodynamic phenomena occurring on scales larger than the accretion radius. Among them, systems with short orbital periods and close to Roche-Lobe overflow or with slow winds, appear highly obscured. In eccentric systems, the variability amplitude can reach even higher factors, because of the contrast of the wind density along the orbit. Four super-giant systems, featuring fast outbursts, very short orbital periods and anomalously low accretion rates, are not yet understood.Simulations of the accretion processes on relatively large scales have progressed and reproduce parts of the observations.

“…It takes information from the the Swift-BAT 70-Month Hard X-ray survey catalog [26], the 4th INTEGRAL-IBIS catalog [32], and the 3rd Fermi -LAT catalog [7]. Noteworthy, the latter catalog contains more than 1000 unidentified sources in the 100 MeV -300 GeV range with no counterparts at other wavelength, and most of them will be detected by e-ASTROGAM, in addition to a relevant number of new unidentified sources.…”

e-ASTROGAM ('enhanced ASTROGAM') is a breakthrough Observatory space mission, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated to the study of the non-thermal Universe in the photon energy range from 0.3 MeV to 3 GeV -the lower energy limit can be pushed to energies as low as 150 keV, albeit with rapidly degrading angular resolution, for the tracker, and to 30 keV for calorimetric detection. The mission is based on an advanced space-proven detector technology, with unprecedented sensitivity, angular and energy resolution, combined with polarimetric capability. Thanks to its performance in the MeV-GeV domain, substantially improving its predecessors, e-ASTROGAM will open a new window on the non-thermal Universe, making pioneering observations of the most powerful Galactic and extragalactic sources, elucidating the nature of their relativistic outflows and their effects on the surroundings. With a line sensitivity in the MeV energy range one to two orders of magnitude better than previous generation instruments, e-ASTROGAM will determine the origin of key isotopes fundamental for the understanding of supernova explosion and the chemical evolution of our Galaxy. The mission will provide unique data of significant interest to a broad astronomical community, complementary to powerful observatories such as LIGO-Virgo-GEO600-KAGRA, SKA, ALMA, E-ELT, TMT, LSST, JWST, Athena, CTA, IceCube, KM3NeT, and the promise of eLISA.
