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…
Early results from the SVOM Observatory Science program
A. Coleiro, L. Tao, F. Cangemi +44
We present the organisation and early results from the Observatory Science program of the Space-based multi-band astronomical Variable Objects Monitor (SVOM), based on data collect…
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…
SVOM Science User Support at FSC
A. Claret, D. Turpin, C. Moreau +16
The SVOM mission, a Sino-French collaboration dedicated to Gamma-Ray Bursts (GRBs) and transient sources, began scientific operations in 2025. This paper describes the ground compu…
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…
