Spectro-polarimetric study of the black hole X-ray binary Swift J1727.8-1613 in the JED-SAD framework
R. Muhammad, P. -O. Petrucci, W. Zhang +10
Context. Swift J1727.8-1613 is an X-ray binary observed during its 2023-2024 outburst, including bright and dim hard states with similar X-ray polarimetric signatures but fluxes di…
Thermal solutions of strongly magnetized disks and the hysteresis in X-ray binaries
Nicolas Scepi, Jason Dexter, Mitchell C. Begelman +3
X-ray binaries (XRBs) exhibit spectral hysteresis for luminosities in the range , with a hard X-ray spectral state that persists from…
The jet emitting disk standard accretion disk model applied to the active galactic nuclei ultra violet Xray correlation
Samuel Barnier, Pierre-Olivier Petrucci, Jonathan Ferreira +1
The non linear correlation between the UV and X-ray emission observed in Active Galactic Nuclei remains a puzzling question that challenged accretion models. While the UV emission…
Absorption lines from magnetically driven winds in X-ray binaries II: high resolution observational signatures expected from future X-ray observatories
Susmita Chakravorty, Pierre-Olivier Petrucci, Sudeb Ranjan Datta +12
In our self-similar, analytical, magneto-hydrodynamic (MHD) accretion-ejection solution, the density at the base of the outflow is explicitly dependent on the disk accretion rate -…
Are Low-Frequency Quasi-Periodic Oscillations seen in accretion flows the disk response to a jet instability?
Jonathan Ferreira, Gregoire Marcel, Pierre-Olivier Petrucci +7
Low Frequency Quasi-Periodic Oscillations or LF QPOs are ubiquitous in BH X-ray binaries and provide strong constraints on the accretion-ejection processes. Although several models…
Clues on jet behavior from simultaneous radio-X-ray fits of GX339-4
S. Barnier, P. -O. Petrucci, J. Ferreira +9
Understanding the mechanisms of accretion-ejection during X-ray binaries outbursts has been a problem for several decades. It is still not clear yet what controls the spectral evol…
