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…
Simultaneous mm/X-ray intraday variability in the radio-quiet AGN MCG+08-11-11
P. O. Petrucci, V. Piétu, E. Behar +10
Most of the Active Galactic Nuclei (AGN) are radio-quiet (RQ) and, differently from radio-loud (RL) AGN, do not show signature of large-scale and powerful jets. The physical origin…
An ultrafast outflow in the black hole candidate MAXI J1810-222?
M. Del Santo, C. Pinto, A. Marino +9
The transient X-ray source MAXI J1810-222 was discovered in 2018 and has been active ever since. A long combined radio and X-ray monitoring campaign was performed with ATCA and Swi…
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…
A unified accretion-ejection paradigm for black hole X-ray binaries. VI. Radiative efficiency and radio-X-ray correlation during four outbursts from GX339-4
G. Marcel, J. Ferreira, P-O. Petrucci +9
The spectral evolution of transient X-ray binaries can be reproduced by an interplay between two flows separated at a radius : a standard accretion disk (SAD) in the outer par…
Tracking the evolution of the accretion flow in MAXI J1820+070 during its hard state with the JED-SAD model
A. Marino, S. Barnier, P. O. Petrucci +10
X-ray binaries in outburst typically show two canonical X-ray spectral states, i.e. hard and soft states, in which the physical properties of the accretion flow and of the jet are…
Expected disk wind properties evolution along an X-ray Binary outburst
P. -O. Petrucci, S. Bianchi, G. Ponti +12
Blueshifted X-ray absorption lines (preferentially from Fe XXV and Fe XXVI present in the 6-8 keV range) indicating the presence of massive hot disk winds in Black Hole (BH) X-ray…
A unified accretion-ejection paradigm for black hole X-ray binaries. V. Low-frequency quasi-periodic oscillations
G. Marcel, F. Cangemi, J. Rodriguez +6
We proposed that the spectral evolution of transient X-ray binaries (XrB) is due to an interplay between two flows: a standard accretion disk (SAD) in the outer parts and a jet-emi…
Modelling the compact jet in MAXI J1836-194 with disc-driven shocks
Mathias Péault, Julien Malzac, Mickael Coriat +9
The black hole candidate MAXI J1836-194 was discovered in 2011 when it went into an outburst, and was the subject of numerous, quasi-simultaneous, multi-wavelength observations in…
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…
A new method for classifying galaxy SEDs from multi-wavelength photometry
Vivienne Wild, Omar Almaini, Michele Cirasuolo +7
We present a new method to classify the broad band optical-NIR spectral energy distributions (SEDs) of galaxies using three shape parameters (super-colours) based on a Principal Co…
