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…
Evolution of the reverberation lag in GX 339-4 at the end of an outburst
B. De Marco, G. Ponti, P. O. Petrucci +13
We studied X-ray reverberation lags in the BHXRB GX 339-4 at the end of the 2014-2015 outburst. We analysed data from a XMM-Newton campaign covering the end of the transition from…
Dark jets in the soft X-ray state of black hole binaries?
S. Drappeau, J. Malzac, M. Coriat +10
X-ray binary observations led to the interpretation that powerful compact jets, produced in the hard state, are quenched when the source transitions to its soft state. The aim of t…
Absorption lines from magnetically-driven winds in X-ray binaries
S. Chakravorty, P-O. Petrucci, J. Ferreira +8
High resolution X-ray spectra of black hole X-ray binaries (BHBs) show blueshifted absorption lines from disk winds which seem to be equatorial. Winds occur in the Softer (disk-dom…
The influence of collimation on the appearance of relativistic jets
P. O. Petrucci, T. Boutelier, G. Henri
The question of the collimation of relativistic jets is the subject of a lively debate in the community. We numerically compute the apparent velocity and the Doppler factor of a no…
The pertinence of Jet Emitting Discs physics to Microquasars: Application to Cygnus X-1
P. O. Petrucci, J. Ferreira, G. Henri +2
The interpretation of the X-ray spectra of X-ray binaries during their hard states requires a hot, optically thin medium. There are several accretion disc models in the literature…
