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…

Evidence for low kick velocities among high-mass X-ray binaries in the Small Magellanic Cloud from the spatial correlation function

Arash Bodaghee, Vallia Antoniou, Andreas Zezas +7

We present the two-point cross-correlation function between high-mass X-ray binaries (HMXBs) in the Small Magellanic Cloud (SMC) and their likely birthplaces (OB Associations: OBAs…

Using Chandra Localizations and Gaia Distances and Proper Motions to Classify Hard X-ray Sources Discovered by INTEGRAL

John A. Tomsick, Benjamin M. Coughenour, Jeremy Hare +7

Here we report on X-ray observations of ten 17-60 keV sources discovered by the INTEGRAL satellite. The primary new information is sub-arcsecond positions obtained by the Chandra X…

Investigating the mini and giant radio flare episodes of Cygnus X-3

E. Egron, A. Pellizzoni, S. Righini +16

The microquasar Cygnus X-3 underwent a giant radio flare in April 2017, reaching a maximum flux of Jy at 8.5 GHz. We present results from a long monitoring campaign car…
