Single-dish and VLBI observations of Cygnus X-3 during the 2016 giant flare episode
E. Egron, A. Pellizzoni, M. Giroletti +34
In September 2016, the microquasar Cygnus X-3 underwent a giant radio flare, which was monitored for 6 days with the Medicina Radio Astronomical Station and the Sardinia Radio Tele…
Positron annihilation signatures associated with the outburst of the microquasar V404 Cygni
Thomas Siegert, Roland Diehl, Jochen Greiner +7
Microquasars are stellar-mass black holes accreting matter from a companion star and ejecting plasma jets at almost the speed of light. They are analogues of quasars that contain s…
Chandra X-Ray Spectroscopy of the Focused Wind in the Cygnus X-1 System. II. The Nondip Spectrum in the Low/Hard State - Modulations with Orbital Phase
Ivica Miškovičová, Natalie Hell, Manfred Hanke +14
The accretion onto the black hole in the system HDE 226868/Cygnus X-1 is powered by the strong line driven stellar wind of the O-type donor star. We study the X-ray properties of t…
Revealing the broad iron Kalpha line in Cygnus X-1 through simultaneous XMM-Newton, RXTE, and INTEGRAL observations
Refiz Duro, Thomas Dauser, Victoria Grinberg +15
We report on the analysis of the broad Fe Kalpha line feature of Cygnus X-1 in the spectra of four simultaneous hard intermediate state observations made with the X-ray Multiple Mi…
Spectral and timing evolution of the bright failed outburst of the transient black hole Swift J174510.8-262411
M. Del Santo, T. M. Belloni, J. A. Tomsick +13
We studied time variability and spectral evolution of the Galactic black hole transient Swift J174510.8-262411 during the first phase of its outburst. INTEGRAL and Swift observatio…
Correlated optical, X-ray, and gamma-ray flaring activity seen with INTEGRAL during the 2015 outburst of V404 Cygni
J. Rodriguez, M. Cadolle Bel, J. Alfonso-Garzón +20
After 25 years of quiescence, the microquasar V404 Cyg entered a new period of activity in June 2015. This X-ray source is known to undergo extremely bright and variable outbursts…
