The First X-ray Eclipse of Igr J16479-4514?

چکیده
We report on the first long (∼32 ks) pointed XMM-Newton observation of the supergiant fast X-ray transient IGR J16479-4514. Results from the timing, spectral and spatial analysis of this observation show that the X-ray source IGR J16479-4514 underwent an episode of sudden obscuration, possibly an X-ray eclipse by the supergiant companion. We also found evidence for a soft X-ray extended halo around the source that is most readily interpreted as due to scattering by dust along the line of sight to IGR J16479-4514.

Swift observations of IGR J 16479 - 4514 in outburst ( Research Note )
Aims. The supergiant fast X-ray transient source IGR J16479-4514 was observed in outburst two times with Swift. Its quiescent state was investigated in-depth only once in 2008 through a relatively long pointed observation with XMM-Newton. The latter observation was taken about 1.7 days after the outburst in 2008, and showed an X-ray eclipse-like event, likely caused by the supergiant companion....
متن کاملIGR J 16479 - 4514 : the first eclipsing supergiant fast X - ray transient ?
Supergiant fast X-ray transients are a new class of high mass X-ray binaries recently discovered with INTEGRAL. Hours long outbursts from these sources have been observed on numerous occasions at luminosities of ∼10-10 erg s, whereas their low level activity at∼10-10 erg s has not been deeply investigated yet due to the paucity of long pointed observations with high sensitivity X-ray telescopes...

INTEGRAL monitoring of the Galactic Plane in the last 5 years revealed a new subclass of High Mass X-ray Binaries (HMXBs), the Supergiant Fast X-ray Transients (SFXTs). They display flares lasting from minutes to hours, with peak luminosity of 1036 −1037 erg s−1 and a frequent long term flaring activity reaching an X-ray luminosity of 1033 − 1034 erg s−1, as recently detected by the Swift satel...
متن کاملMonitoring Supergiant Fast X–ray Transients with Swift. Results from the first year
The advent of Swift has allowed, for the first time, the possibility to give Supergiant Fast X–ray Transients (SFXTs), the new class of High Mass X–ray Binaries discovered by INTEGRAL, non serendipitous attention throughout most phases of their life. In this paper we present our results based on the first year of intense Swift monitoring of four SFXTs, IGR J16479−4514, XTE J1739−302, IGR J17544...
متن کاملMonitoring Supergiant Fast X-ray Transients with Swift. Rise to the Outburst in Igr J16479−4514
IGR J16479−4514 is a Supergiant Fast X–ray Transient (SFXT), a new class of High Mass X–ray Binaries, whose number is rapidly growing thanks to the INTEGRAL observations of the Galactic plane. It was regularly monitored with Swift/XRT since November 2007, to study the quiescent emission, the outburst properties and their recurrence. A new bright outburst, reaching fluxes above 10 −9 erg cm −2 s...
