Unprecedentedly bright X-ray flaring in Cygnus X-1 observed by INTEGRAL
P. Thalhammer, T. Bouchet, J. Rodriguez +15
We study three extraordinarily bright X-ray flares originating from Cyg X-1 seen on 2023 July 10 detected with INTEGRAL. The flares had a duration on the order of only ten minutes…
INTEGRAL/IBIS polarization detection in the hard and soft intermediate states of Swift J1727.8-1613
Tristan Bouchet, Jérôme Rodriguez, Floriane Cangemi +5
Soft gamma-ray emission (100 keV -- 10 MeV) has previously been detected in the hard state of several microquasars. In some sources, this emission was found to be highly polarized…
Drop in the hard pulsed fraction and a candidate cyclotron line in IGR J16320-4751 seen by NuSTAR
Arash Bodaghee, Alan J. -L. Chiu, John A. Tomsick +10
We report on a timing and spectral analysis of a 50-ks NuSTAR observation of IGR J16320-4751 (= AX J1631.9-4752); a high-mass X-ray binary hosting a slowly-rotating neutron star. I…
INTEGRAL study of MAXI J1535-571, MAXI J1820+070 and MAXI J1348-630 outbursts -- I. Detection and polarization properties of the high-energy emission
F. Cangemi, J. Rodriguez, T. Belloni +5
In black hole X-ray binaries, a non-thermal high-energy component is sometimes detected at energies above 200 keV. The origin of this component is debated and distinct spectral mod…
The spectral-timing analysis of Cygnus X-1 with Insight-HXMT
M. Zhou, V. Grinberg, Q. -C. Bu +12
Cygnus X-1, as the first discovered black hole binary, is a key source for understanding the mechanisms of state transitions, and the scenarios of accretion in extreme gravity fiel…
Discovery of X-ray Pulsations from the INTEGRAL Source IGR J11014-6103
J. P. Halpern, J. A. Tomsick, E. V. Gotthelf +6
We report the discovery of PSR J1101-6101, a 62.8 ms pulsar in IGR J11014-6103, a hard X-ray source with a jet and a cometary tail that strongly suggests it is moving away from the…
Long term variability of Cygnus X-1 V. State definitions with all sky monitors
V. Grinberg, N. Hell, K. Pottschmidt +14
We present a scheme to determine the spectral state of the canonical black hole Cyg X-1 using data from previous and current X-ray all sky monitors (RXTE-ASM, Swift-BAT, MAXI, and…
A Suzaku X-ray observation of one orbit of the supergiant fast X-ray transient IGR J16479-4514
L. Sidoli, P. Esposito, V. Sguera +6
We report on a 250 ks long X-ray observation of the supergiant fast X-ray transient (SFXT) IGR J16479-4514 performed with Suzaku in 2012 February. About 80% of the short orbital pe…
X-ray and Near Infrared observations of the obscured accreting pulsar IGR J18179-1621
M. A. Nowak, A. Paizis, J. Rodriguez +6
IGR J18179-1621 is an obscured accreting X-ray pulsar discovered by INTEGRAL on 2012 February 29. We report on our 20 ksec Chandra-High Energy Transmission Gratings Spectrometer ob…
Clustering between high-mass X-ray binaries and OB associations in the Milky Way
Arash Bodaghee, John A. Tomsick, Jerome Rodriguez +1
We present the first direct measurement of the spatial cross-correlation function of high-mass X-ray binaries (HMXBs) and active OB star-forming complexes in the Milky Way. This re…
Polarized Gamma-ray Emission from the Galactic Black Hole Cygnus X-1
P. Laurent, J. Rodriguez, J. Wilms +3
Because of their inherently high flux allowing the detection of clear signals, black hole X-ray binaries are interesting candidates for polarization studies, even if no polarizatio…
Broadband Suzaku observations of IGR J16207-5129
Arash Bodaghee, John A. Tomsick, Jerome Rodriguez +3
An analysis of IGR J16207-5129 is presented based on observations taken with Suzaku. The data set represents ~80 ks of effective exposure time in a broad energy range between 0.5 a…
Long-term multi-wavelength studies of GRS 1915+105 I. A high-energy and mid-infrared focus with RXTE, INTEGRAL, and Spitzer
F. Rahoui, S. Chaty, J. Rodriguez +3
To date, mid-infrared properties of Galactic black hole binaries have barely been investigated in the framework of multi-wavelength campaigns. Yet, studies in this spectral domain…
