“…Similar SFXT-like flaring activity was also recorded several times with MAXI and INTEGRAL Sguera et al, 2006b;Walter and Zurita Heras, 2007b). Hours-long outbursts were also detected by Swift /BAT and followed-up a few times by Swift /XRT (de Pasquale et al, 2010;Romano et al, 2010aRomano et al, , 2011bRomano et al, , 2012a.…”

“…The fast flaring activity detected from this source with INTEGRAL led Sguera et al (2006b) to associate this source with the SFXT class (see also Morris et al, 2009a). A Chandra observation performed in the direction of the source permitted to identify the supergiant companion and provide further support to this association (Tomsick et al, 2006a;Rahoui et al, 2008a).…”

“…Several outbursts from this source were detected with ASCA (Sakano et al, 2002), RXTE (Smith et al, 2006), INTEGRAL (Sunyaev et al, 2003a;Lutovinov et al, 2005b;Sguera et al, 2005Sguera et al, , 2006bBlay et al, 2008), and Swift /BAT (Sidoli et al, 2009a,c;Romano et al, 2009bRomano et al, , 2011b. The source was also observed during faint X-ray states by Chandra and XMM-Newton, revealing the typical variability of the SFXT sources (Smith et al, 2006;Bozzo et al, 2010;Bodaghee et al, 2011b).…”

“…IGR J16418-4532 was discovered by INTEGRAL in 2003 (Tomsick et al, 2004) and later classified as an SFXT on the basis of its fast flaring activity (Sguera et al, 2006b). The discovery of the orbital period of the source at 3.75 days, together with some hint for the presence of an X-ray eclipse, was reported by .…”

“…These hard X-ray transients produce short and bright flares with typical durations of a few hours and peak fluxes of few tens to hundred mCrab (in the energy band ∼20-100 keV). Given the short and sporadic nature of these events, the large field of view of the IBIS/ISGRI imager on-boad INTEGRAL proved to be particularly well suited to search for SFXT sources (Sguera et al, 2006a;Walter and Zurita Heras, 2007a). So far, about 15 objects have been identified among the SFXTs (Falanga et al, 2011).…”

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.

The landscape of Galactic X-ray sources made of accreting binaries, isolated objects and active stellar coronae has been significantly modified by the advent of the Chandra, XMM-Newton and INTEGRAL satellites. New types of relatively low X-ray luminosity X-ray binaries have been unveiled in the Galactic disc, while deep observations of the central regions have revealed large numbers of X-ray binaries of so far poorly constrained nature. Because of the high spatial resolution needed and faint X-ray luminosities generally emitted, studying the dependency of the X-ray source composition with parent stellar population, Galactic disc, bulge, nuclear bulge, etc., is only practicable in our Galaxy. The evolutionary links between low LX X-ray binaries and classical X-ray luminous accreting systems are still open in many cases. In addition, the important question of the nature of the compact sources contributing to the Galactic ridge hard X-ray emission remains unresolved. We review the most important results gathered by XMM-Newton over the last years in this domain and show how future observations could be instrumental in addressing several of these issues. The galaxy viewed in X-raysThe discovery of luminous X-ray binaries in the 1960s marked the birth of X-ray astronomy by revealing the source of their power as accretion onto neutron stars or black holes. Among the most salient outcomes of these early studies was a rapid advance in our understanding of accretion disc physics and of emission mechanisms in extreme conditions of gravity and magnetic fields. Sustained improvements in the sensitivity and spatial resolution of X-ray instruments further revealed that many, if not all, classes of astrophysical objects can emit X-rays. In particular, the Einstein observatory and a few years later the ROSAT satellite, with their on-board X-ray telescopes, unveiled the ubiquitous high energy emission of stellar coronae, young stars, early type stars, cataclysmic variables, isolated neutron stars, quiescent stages of low and high mass X-ray binaries.It is now clear that the bright "historical" X-ray sources constitute only the tip of an iceberg harbouring an enormous number of fainter X-ray emitters with typical X-ray luminosities in the range of 10 26−36 erg s −1 . These sources exhibit a wide range of X-ray spectra and timing signatures reflecting very different physical states and emitting mechanisms. Unquestionably X-ray observations have opened a new window for the understanding of such objects.It is far beyond the scope of this short review paper to encompass all astrophysical processes at work in Galactic X-ray sources and we will only recall here the main classes of X-ray emitters. Accretion onto a compact object, a white dwarf, a neutron star or a black hole accounts for the X-ray emission of the most luminous X-ray binaCorresponding author: motch@astro.u-strasbg.fr ries with L X in the range of 10 29−39 erg s −1 depending on accretion rate and depth of the gravitational potential well.

New INTEGRAL sources and TeV emission

The Multi-Messenger Approach to High-Energy Gamma-Ray Sources

View full text Add to dashboard Cite

INTEGRAL is operational since more than three years and producing high quality data that allows to detect fainter new hard X-ray sources. The new sources, identified until now, are mostly active galactic nuclei and absorbed or transient high mass X-ray binaries. TeV emission could be expected from the new high mass X-ray binaries accreting dense clumps of stellar wind. INTEGRAL sources with TeV counterparts are discussed.
