Discovery of slow X-ray pulsations in the high-mass X-ray binary 4U 2206+54
P. Reig, J. M Torrejon, I. Negueruela +3
The source 4U 2206+54 is one of the most enigmatic high-mass X-ray binaries. In spite of intensive searches, X-ray pulsations have not been detected in the time range 0.001-1000 s.…
INTEGRAL observations of Her X-1
D. Klochkov, R. Staubert, K. Postnov +6
Aims: We investigate the X-ray spectral and timing properties of the accreting X-ray pulsar Her X-1 observed with the INTEGRAL satellite in July-August 2005. Methods: The data anal…
Pulse phase resolved analysis of the HMXB Cen X-3 over two binary orbits
S. Suchy, K. Pottschmidt, J. Wilms +7
We present a detailed analysis of observations of the high mass X-ray binary Cen X-3 spanning two consecutive binary orbits performed with the RXTE satellite in early March 1997. T…
Tracking the Orbital and Super-orbital Periods of SMC X-1
Sarah Trowbridge, Michael A. Nowak, Joern Wilms
The High Mass X-ray Binary (HMXB) SMC X-1 demonstrates an orbital variation of 3.89 days and a super-orbital variation with an average length of 55 days. As we show here, however,…
A 0535+26 in the August/September 2005 outburst observed by RXTE and INTEGRAL
I. Caballero, P. Kretschmar, A. Santangelo +14
In this Letter we present results from INTEGRAL and RXTE observations of the spectral and timing behavior of the High Mass X-ray Binary A 0535+26 during its August/September 2005 n…
XMM-Newton observations of the brightest Ultraluminous X-ray sources
A-M. Stobbart, T. P. Roberts, J. Wilms
We present an analysis of 13 of the best quality EPIC ULX datasets. We utilise the high signal-to-noise in these ULX spectra to investigate the best descriptions of their spectral…
RXTE Discovery of Multiple Cyclotron Lines during the 2004 December Outburst of V0332+53
K. Pottschmidt, I. Kreykenbohm, J. Wilms +6
We present an analysis of the 2-150 keV spectrum of the transient X-ray pulsar V0332+53 taken with the Rossi X-Ray Timing Explorer (RXTE) in 2004 December. We report on the detecti…
Crab: the standard X-ray candle with all (modern) X-ray satellites
M. G. F. Kirsch et al.
Various X-ray satellites have used the Crab as a standard candle to perform their calibrations in the past. The calibration of XMM-Newton, however, is independent of the Crab nebul…
INTEGRAL-RXTE observations of Cygnus X-1
K. Pottschmidt, J. Wilms, M. Chernyakova +11
We present first results from contemporaneous observations of Cygnus X-1 with INTEGRAL and RXTE, made during INTEGRAL's performance verification phase in 2002 November and December…
