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…
Fast Optical Variability of the TeV Blazar PKS 1725+123 Observed by SVOM-VT and Insights from Multi-wavelength Follow-up Observations
Shuo-Yu Liu, Yu-Wei Yu, Ji-Shun Lian +29
PKS 1725+123 is a flat-spectrum radio quasar (FSRQ) with a redshift of . The detection of this object in the TeV band was reported by the MAGIC telescopes and H.E.S.S. in…
Discovery of EP J175257.3-351923 as a Candidate Black Hole Low-Mass X-ray Binary
G. L. Huang, Q. C. Zhao, L. Tao +30
We report the discovery of a new X-ray transient, EP J175257.3-351923 (EP250916a), by the Einstein Probe (EP) near the Galactic plane. The outburst lasted for at least 250\,days, r…
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 GRB joint scientific analysis pipeline of the ECLAIRs and GRM instruments on board SVOM
F. Piron, F. Daigne, T. Maiolino +35
The study of the prompt high-energy emission of Gamma-Ray Bursts (GRBs) with SVOM relies on the observations performed by ECLAIRs (4-150 keV) and the Gamma-Ray Monitor (GRM, 0.015-…
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…
