A failed outburst of H 1743 - 322
We report on a campaign of X-ray and soft γ-ray observations of the black hole candidate H 1743-322 (also named IGR J17464-3213), performed with the RXTE, INTEGRAL and Swift satellites. The source was observed during a short outburst between 2008 October 03 and 2008 November 16. The evolution of the hardness-intensity diagram throughout the outburst is peculiar, in that it does not follow the c...
متن کاملA truncated accretion disk in the galactic black hole candidate source H 1743 - 322
To investigate the geometry of the accretion disk in the source H1743-322, we have carried out a detailed X-ray temporal and spectral study using RXTE pointed observations. We have selected all data pertaining to the Steep Power Law (SPL) state during the 2003 outburst of this source. We find anti-correlated hard X-ray lags in three of the observations and the changes in the spectral and timing...
متن کاملDisc – jet coupling in the 2009 outburst of the black hole candidate H 1743 − 322
We present an intensive radio and X-ray monitoring campaign on the 2009 outburst of the Galactic black hole candidate X-ray binary H1743−322. With the high angular resolution of the Very Long Baseline Array, we resolve the jet ejection event and measure the proper motions of the jet ejecta relative to the position of the compact core jets detected at the beginning of the outburst. This allows u...
متن کاملTomographic reflection modelling of quasi - periodic oscillations in the black hole binary H 1743 – 322
Accreting stellar mass black holes (BHs) routinely exhibit Type-C quasi-periodic oscillations (QPOs). These are often interpreted as Lense-Thirring precession of the inner accretion flow, a relativistic effect whereby the spin of the BH distorts the surrounding space-time, inducing nodal precession. The best evidence for the precession model is the recent discovery, using a long joint XMM-Newto...
متن کاملINTEGRAL observations of the black hole candidate H 1743−322 in outburst
INTEGRAL made 3 observations in 2003 April of the black hole candidate H 1743−322 during the rising part, and close to the maximum, of an outburst. H 1743−322 was previously observed in outburst in 1977–1978. The source is located in a crowded region of the sky (l = 357, b = −2) and at least 18 sources are clearly detected in the field of view of the ISGRI gamma-ray imager during a 277 ks expos...
