Accretion and ejection in black-hole X-ray transients
N. D. Kylafis, T. M. Belloni
Aims: We summarize the current observational picture of the outbursts of black-hole X-ray transients (BHTs), based on the evolution traced in a hardness-luminosity diagram (HLD), a…
X-ray coherent pulsations during a sub-luminous accretion disk state of the transitional millisecond pulsar XSS J12270-4859
A. Papitto, D. de Martino, T. M. Belloni +4
We present the first detection of X-ray coherent pulsations from the transitional millisecond pulsar XSS J12270-4859, while it was in a sub-luminous accretion disk state characteri…
Millihertz quasi-periodic oscillations and broad iron line from LMC X-1
Md. Shah Alam, G. C. Dewangan, T. Belloni +2
We study the temporal and energy spectral characteristics of the persistent black hole X-ray binary LMC X-1 using two XMM-Newton and a Suzaku observation. We report the discovery o…
A 100 mHz QPO in the X-ray emission from IGR J17361-4441
E. Bozzo, A. Papitto, C. Ferrigno +1
IGR J17361-4441 was discovered by INTEGRAL undergoing its first detectable X-ray outburst in 2011 and initially classified as an accreting X-ray binary in the globular cluster NGC…
Multiwavelength observations of the black hole transient Swift J1745-26 during the outburst decay
Emrah Kalemci, Mehtap Ozbey Arabaci, Tolga Guver +12
We characterized the broad-band X-ray spectra of Swift J1745-26 during the decay of the 2013 outburst using INTEGRAL ISGRI, JEM-X and Swift XRT. The X-ray evolution is compared to…
Fast variability from black-hole binaries
Tomaso M. Belloni, Luigi Stella
Currently available information on fast variability of the X-ray emission from accreting collapsed objects constitutes a complex phenomenology which is difficult to interpret. We r…
