The compact jets of the black hole X-ray binary Swift J1753.5-0127 during its 2023-2024 outburst
Noa Grollimund, Stéphane Corbel, Lauren Rhodes +14
X-ray binaries are excellent laboratories to study the coupling between accretion and ejection phenomena around compact objects through multiwavelength observations. Swift J1753.5-…
A unified modeling of X-ray and gamma-ray spectro-polarimetric data: the case of Cygnus X-1
Tristan Bouchet, Thomas Siegert, Victoria Grinberg +4
Recent X-ray and soft gamma-ray spectro-polarimetric observations of black hole X-ray binaries, such as Cygnus X-1, reveal discrepancies that challenge current models of accretion…
Cosmological - Pair-Production Background
Mika A. Gelowicz, Thomas Siegert, Saurabh Mittal +10
The origin of positrons is one of the unsolved puzzles in astrophysics as the majority of sources are still unidentified. The Cosmic Photon Background (CPB) is the isotropic radiat…
Stellar flares cannot explain the Galactic 511 keV emission
Saurabh Mittal, Thomas Siegert, Francesca Calore +12
The origin of the 511 keV line signal in the Milky Way remains unresolved despite decades of observations. The measured flux of $\sim 3 \times 10^{-3}\,\mathrm{ph\,cm^{-2}\,s^{-1}}…
The SVOM / ECLAIRs Scientific Analysis Pipeline
A. Goldwurm, P. Bacon, N. Bellemont +10
This paper reports on the scientific pipeline for the analysis of the ECLAIRs data of the SVOM mission. We describe the overall procedure, the different steps and the main algorith…
In-flight calibration of the INTEGRAL/IBIS Compton mode: Application to the Crab Nebula polarization
Tristan Bouchet, Philippe Laurent, Floriane Cangemi +1
The INTEGRAL satellite explored the gamma-ray sky since its launch on October 17, 2002, and until the end of its scientific operation on February 28, 2025. A large fraction of the…
Detection of Oscillations in a Type I X-Ray Burst of 4U 0614+091 with SVOM/ECLAIRs
Sébastien Le Stum, Floriane Cangemi, Alexis Coleiro +29
On 2025 January 10, a thermonuclear (Type I) X-ray burst from the neutron star low-mass X-ray binary \textit{4U~0614+091} was detected with the ECLAIRs instrument on board the \tex…
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…
Observation of microquasars high-energy emission with INTEGRAL
T. Bouchet, J. Rodriguez, F. Cangemi +1
Microquasars are Black Hole X-ray binaries (BHXB) which can eject material in the form of a bipolar jet, similarly to quasars, but at much smaller scales. Their high-energy emissio…
