Spectral and timing evolution of the bright failed outburst of the transient black hole Swift J174510.8-262411

Understand

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 observations collected from 2012 September 16 until October 30 have been used.
• The total squared fractional rms values did not drop below 5% and QPOs, when present, were type-C, indicating that the source never made the transition to the soft-intermediate state.
• Even though the source was very bright (up to 1 Crab in hard X-rays), it showed a so called failed outburst as it never reached the soft state.
