Gamma-ray observations of the microquasars Cygnus X-1, Cygnus X-3, GRS 1915+105, and GX 339-4 with the Fermi Large Area Telescope
Arash Bodaghee, John A. Tomsick, Katja Pottschmidt +3
Detecting gamma-rays from microquasars is a challenging but worthwhile endeavor for understanding particle acceleration, the jet mechanism, and for constraining leptonic/hadronic e…
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…
The Supergiant Fast X-ray Transient with the shortest orbital period: Suzaku observes one orbit in IGRJ16479-4514
L. Sidoli, P. Esposito, V. Sguera +6
The eclipsing hard X-ray source IGR J16479-4514 is the Supergiant Fast X-ray Transient (SFXT) with the shortest orbital period (3.32 days). This allowed us to perform a 250 ks long…
