An XMM-Newton Spectral and Timing Study of IGR J16207-5129: An Obscured and Non-Pulsating HMXB
John A. Tomsick, Sylvain Chaty, Jerome Rodriguez +3
We report on a 12 hr XMM-Newton observation of the supergiant High-Mass X-ray Binary IGR J16207-5129. This is only the second soft X-ray (0.4-15 keV, in this case) study of the sou…
Swift follow-up observations of 17 INTEGRAL sources of uncertain or unknown nature
J. Rodriguez, J. A. Tomsick, S. Chaty
(abridged) We analysed data from observations of 17 INTEGRAL sources made with the Swift satellite. We refine the position of the hard X-ray sources to an accuracy of a few arcsec.…
Discovery of an eccentric 30 days period in the supergiant X-ray binary SAX J1818.6-1703 with INTEGRAL
J. A. Zurita Heras, S. Chaty
SAX J1818.6-1703 is a flaring transient X-ray source serendipitously discovered by BeppoSAX in 1998 during an observation of the Galactic centre. The source was identified as a Hig…
Mid-infrared VISIR and Spitzer observations of the surroundings of the magnetar SGR 1806-20
F. Rahoui, S. Chaty, P. O. Lagage
We report mid-infrared observations of SGR 1806-20 and its environment - with the highest spatial resolution in this domain to date - using ESO/VISIR in 2005 and 2006, and we retri…
IGR J18483-0311: a new intermediate supergiant fast X-ray transient
F. Rahoui, S. Chaty
IGR J18483-0311 is a high-mass X-ray binary recently discovered by INTEGRAL. Its periodic fast X-ray transient activity and its position in the Corbet diagram - although ambiguous…
INTEGRAL sources: from obscured high mass X-ray binaries to supergiant fast X-ray transients
S. Chaty
A new type of high-energy binary system has been revealed by the INTEGRAL satellite. These sources are being unveiled by means of multi-wavelength optical, near- and mid-infrared o…
Obscured High Mass X-Ray Binaries and Supergiant Fast X-ray Transients: Infrared Observations of INTEGRAL Sources
Sylvain Chaty
A new type of high-energy binary system has been revealed by the INTEGRAL satellite. These sources are being unveiled by means of multi-wavelength optical, near- and mid-infrared o…
Multi-wavelength observations of Galactic hard X-ray sources discovered by INTEGRAL. I. The nature of the companion star
Sylvain Chaty, Farid Rahoui, Cédric Foellmi +3
Context: The INTEGRAL hard X-ray observatory has revealed an emerging population of highly obscured X-ray binary systems through multi-wavelength observations. Previous studies hav…
Multi-wavelength observations of Galactic hard X-ray sources discovered by INTEGRAL. II. The environment of the companion star
Farid Rahoui, Sylvain Chaty, Pierre-Olivier Lagage +1
Context: The INTEGRAL mission has led to the discovery of a new type of supergiant X-ray binaries (SGXBs), whose physical properties differ from those of previously known SGXBs. Th…
INTEGRAL, XMM-Newton and ESO/NTT identification of AX J1749.1-2733: an obscured and probably distant Be/X-ray binary
J. A. Zurita Heras, S. Chaty
AX J1749.1-2733 is an unclassified transient X-ray source discovered during surveys by ASCA in 1993-1999. A multi-wavelength study in NIR, optical, X-rays and hard X-rays is undert…
