چکیده

We report on the analysis of an XMM observation of the X-ray source IGR J16320–4751 = AX J1631.9– 4752. Our analysis allowed us to obtain the most accurate X-ray position to date (Rodriguez et al. 2003), and to identify a likely infrared counterpart (Tomsick et al. 2003). We present the detailed analysis of the IGR J16320–4751 XMM spectra. The PN spectrum can be well represented by a single powerlaw or a comptonized spectrum (comptt). The current analysis and the comparison with the properties of other sources favor the possibility that the source is a Galactic X-Ray Binary (XRB). The identification of two candidate IR counterparts is in good agreement with this identification. The hard spectrum previously seen with ASCA, and the brightness of the candidate counterparts indicate that IGR J16320–4751 is most probably a High Mass X-ray Binary, hosting a neutron star.

An XMM - Newton Observation of IGR J 16320 − 4751 = AX J 1631 . 9 − 4752

The hard X-ray sensitivity and arcminute position accuracy of the recently launched International Gamma-Ray Laboratory (INTEGRAL) has lead to the (re-)discovery of a class of heavily absorbed hard X-ray sources lying in the Galactic plane. We report on the analysis of an XMM observation of such a source IGR J16320−4751 = AX J1631.9−4752. Our analysis allowed us to obtain the most accurate X-ray...

IGR J16320 − 4751 was re–discovered by IBIS/ISGRI on board INTEGRAL in early February 2003 during the observation of the black hole candidate 4U1630 − 47 (PI Tomsick). This source, already observed by ASCA and BeppoSAX, belongs to the class of heavily absorbed objects (N H > 10 23 cm −2) that populate some arms of the Galaxy. Soon after the rediscovery by IBIS/ISGRI, the source was observed by ...

IGR J 16393 − 4643 : a new heavily - obscured X - ray pulsar

An analysis of the high-energy emission from IGR J16393−4643 (=AX J1639.0−4642) is presented using data from INTEGRAL and XMM-Newton. The source is persistent in the 20–40 keV band at an average flux of 5.1 × 10 −11 ergs cm −2 s −1 , with variations in intensity by at least an order of magnitude. A pulse period of 912.0±0.1 s was discovered in the ISGRI and EPIC light curves. The source spectru...

RXTE observations of strongly absorbed sources IGR J 16318 - 4848 and IGR J 16358 - 4726

Results of analysis of RXTE observations of strongly absorbed X-ray sources IGR J16318-4848 and IGR J16358-4726 are presented. Careful subtraction of Galactic ridge emission contribution to the observed spectra of RXTE/PCA allowed us to obtain the spectra of the sources in 3–25 keV energy band. Spectra of the sources cold be well described by a power law with photoabsorption. It is shown that t...
