Unraveling the cooling trend of the Soft Gamma Repeater, SGR 1627-41
C. Kouveliotou, D. Eichler, P. M. Woods +7
SGR 1627-41 was discovered in 1998 after a single active episode which lasted \~6 weeks. We report here our monitoring results of the decay trend of the persistent X-ray luminosity…
Chandra Phase-Resolved Spectroscopy of the Crab Pulsar
Martin C. Weisskopf, Stephen L. O'Dell, Frits Paerels +3
We present the first phase-resolved study of the X-ray spectral properties of the Crab Pulsar that covers all pulse phases. The superb angular resolution of the Chandra X-ray Obser…
Composition of the Chandra ACIS contaminant
Herman L. Marshall, Allyn Tennant, Catherine E. Grant +3
The Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory is suffering a gradual loss of low energy sensitivity due to a buildup of a contaminant. High resoluti…
Probing the Inflow/Out-flow and Accretion Disk of Cyg X-1 in the High State with HETG/Chandra
Y. X. Feng, A. F. Tennant, S. N. Zhang
Cyg X-1 was observed in the high state at the conjunction orbital phase (0) with HETG/Chandra. Strong and asymmetric absorption lines of highly ionized species were detected, such…
The Peculiar X-ray Transient IGR 16358-4726
S. K. Patel, C. Kouveliotou, A. Tennant +9
The new transient IGR 16358-4726 was discovered on 2003 March 19 with INTEGRAL. We detected the source serendipitously during our 2003 March 24 observation of SGR 1627-41 with the…
Luminosity functions of X-ray binaries and the dynamical history of their host galaxies
K. Wu, A. F. Tennant, D. A. Swartz +2
The X-ray sources observed in nearby galaxies show brightness distributions (log(N(>S))--log(S) curves) which can be described as single or broken power laws. Single power-law dist…
