Radio and Gamma-Ray Constraints on the Emission Geometry and Birthplace of PSR J2043+2740
A. Noutsos, A. A. Abdo, M. Ackermann +146
We report on the first year of Fermi gamma-ray observations of pulsed high-energy emission from the old PSR J2043+2740. The study of the gamma-ray efficiency of such old pulsars gi…
Suzaku captures a possible eclipse in IGR J16207-5129 and identifies a weak-flaring state in IGR J17391-3021
A. Bodaghee, J. A. Tomsick, J. Rodriguez +4
We present the results from analyses of Suzaku observations of the supergiant X-ray binaries IGR J16207-5129 and IGR J17391-3021. For IGR J16207-5129, we provide the first broadban…
Confirmation of IGR J01363+6610 as a Be X-ray binary with very low quiescent X-ray luminosity
John A. Tomsick, Craig Heinke, Jules Halpern +4
The field containing the candidate High Mass X-ray Binary IGR J01363+6610 was observed by XMM-Newton on 2009 July 31 for 28 ks. A Be star was previously suggested as the possible c…
The INTEGRAL legacy on High Mass X-ray Binaries
Sylvain Chaty, Juan Antonio Zurita Heras, Arash Bodaghee
Observations with the INTEGRAL satellite have quadrupled the population of supergiant High Mass X-ray Binaries (HMXBs), revealed a previously hidden population of obscured supergia…
Suzaku observes weak flares from IGR J17391-3021 representing a common low-activity state in this SFXT
A. Bodaghee, J. A. Tomsick, J. Rodriguez +4
We present an analysis of a 37-ks observation of the supergiant fast X-ray transient (SFXT) IGR J17391-3021 (=XTE J1739-302) gathered with Suzaku. The source evolved from quiescenc…
Unveiling the nature of IGR J16283-4838
L. J. Pellizza, S. Chaty, N. E. Chisari
Context. One of the most striking discoveries of the INTEGRAL observatory is the existence of a previously unknown population of X-ray sources in the inner arms of the Galaxy. The…
