Impact of the disk magnetization on MHD disk wind signature
Sudeb Ranjan Datta, Susmita Chakravorty, Jonathan Ferreira +8
Observation of blue-shifted X-ray absorption lines indicates the presence of wind from the accretion disk in X-ray binaries. Magnetohydrodynamic (MHD) driving is one of the possibl…
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 -…
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…
The auto and cross angular power spectrum of the Cas A supernova remnant in radio and X-ray
Preetha Saha, Somnath Bharadwaj, Susmita Chakravorty +4
The shell type supernova remnant (SNR) Cas A exhibits structures at nearly all angular scales. Previous studies show the angular power spectrum of the radio emission t…
Hyper-massive Black Holes have Faint Broad and Narrow Emission Lines
Harshitha K. Bhat, Susmita Chakravorty, Dhrubojyoti Sengupta +6
The EUV provides most of the ionization that creates the high equivalent width (EW) broad and narrow emission lines (BELs, NELs) of quasars. Spectra of Hypermassive Schwarzschild b…
A unified accretion-ejection paradigm for black hole X-ray binaries. III. Spectral signatures of hybrid disk configurations
G. Marcel, J. Ferreira, P-O. Petrucci +9
It has been suggested that the cycles of activity of X-ray Binaries (XrB) are triggered by a switch in the dominant disk torque responsible for accretion (paper I). As the disk acc…
