RXTE observations of strongly absorbed sources IGR J 16318 - 4848 and IGR J 16358 - 4726
Results of analysis of RXTE observations of strongly absorbed X-ray sources IGR J16318-4848 and IGR J16358-4726 are presented. Careful subtraction of Galactic ridge emission contribution to the observed spectra of RXTE/PCA allowed us to obtain the spectra of the sources in 3–25 keV energy band. Spectra of the sources cold be well described by a power law with photoabsorption. It is shown that t...
متن کاملThe Faint “heartbeats” of Igr J17091–3624: an Exceptional Black-hole Candidate
We report on the first 180 days of RXTE observations of the outburst of the black hole candidate IGR J17091–3624. This source exhibits a broad variety of complex light curve patterns including periods of strong flares alternating with quiet intervals. Similar patterns in the X-ray light curves have been seen in the (up to now) unique black hole system GRS 1915+105. In the context of the variabi...
متن کاملAn Atlas of Exotic Variability in IGR J 17091 - 3624 : A Comparison with GRS 1915 + 105
We performed an analysis of all RXTE observations of the Low Mass X-ray Binary and Black Hole Candidate IGR J17091-3624 during the 2011-2013 outburst of the source. By creating lightcurves, hardness-intensity diagrams and power density spectra of each observation, we have created a set of 9 variability ‘classes’ that phenomenologically describe the range of types of variability seen in this obj...
متن کاملINTEGRAL and RXTE observations of accreting millisecond pulsar IGR J00291+5934 in outburst
Simultaneous observations of the accretion-powered millisecond pulsar IGR J00291+5934 by International Gamma-Ray Astrophysics Laboratory and Rossi X-ray Timing Explorer during the 2004 December outburst are analysed. The average spectrum is well described by thermal Comptonization with an electron temperature of 50 keV and Thomson optical depth τT ∼ 1 in a slab geometry. The spectral shape is a...
متن کاملPeering through the stellar wind of IGR J19140+0951 with simultaneous INTEGRAL/RXTE observations
We have used the RXTE and INTEGRAL satellites simultaneously to observe the High Mass X-ray binary IGR J19140+0951. The spectra obtained in the 3–80 keV range have allowed us to perform a precise spectral analysis of the system along its binary orbit. The spectral evolution confirms the supergiant nature of the companion star and the neutron star nature of the compact object. Using a simple ste...
