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 paper calculates how photons from the cosmic photon background interact with each other to produce electron‑positron pairs across cosmic time, and evaluates the resulting secon…
Stellar flares cannot explain the Galactic 511 keV emission
Saurabh Mittal, Thomas Siegert, Francesca Calore +12
The authors assess whether stellar flares can produce enough positrons to explain the Milky Way’s 511 keV annihilation line and conclude that flares fall short by several orders of…
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…
