Measurements of Cyclotron Features and Pulse Periods in the High-Mass X-Ray Binaries 4U 1538-522 and 4U 1907+09 with INTEGRAL
Paul Hemphill, Richard Rothschild, Isabel Caballero +4
We present a spectral and timing analysis of INTEGRAL observations of two high mass X-ray binaries, 4U 1538-522 and 4U 1907+09. Our timing measurements for 4U 1538-522 find the pul…
GRO J1008-57: an (almost) predictable transient X-ray binary
M. Kühnel, S. Müller, I. Kreykenbohm +13
A study of archival RXTE, Swift, and Suzaku pointed observations of the transient high mass X-ray binary GRO J1008-57 is presented. A new orbital ephemeris based on pulse arrival t…
Observations of The High Mass X-ray Binary A0535+26 in Quiescence
Richard Rothschild, Alex Markowitz, Paul Hemphill +7
We have analyzed 3 observations of the High Mass X-ray Binary A0535+26 performed by the Rossi X-ray Timing Explorer (RXTE) 3, 5, and 6 months after the last outburst in 2011 Februa…
Cygnus X-1: shedding light on the spectral variability of a black hole
V. Grinberg, N. Hell, J. Wilms +17
The knowledge of the spectral state of a black hole is essential for the interpretation of data from black holes in terms of their emission models. Based on pointed observations of…
Long term variability of Cygnus X-1 V. State definitions with all sky monitors
V. Grinberg, N. Hell, K. Pottschmidt +14
We present a scheme to determine the spectral state of the canonical black hole Cyg X-1 using data from previous and current X-ray all sky monitors (RXTE-ASM, Swift-BAT, MAXI, and…
