Evolution of the accretion disk-corona during bright hard-to-soft state transition: A reflection spectroscopic study with GX 339-4
Navin Sridhar, Javier A. García, James F. Steiner +3
We present the analysis of several observations of the black hole binary GX 339--4 during its bright intermediate states from two different outbursts (2002 and 2004), as observed b…
The 2017 Failed Outburst of GX 339-4: Relativistic X-ray Reflection near the Black Hole Revealed by NuSTAR and Swift Spectroscopy
Javier A. García, John A. Tomsick, Navin Sridhar +12
We report on the spectroscopic analysis of the black hole binary GX 339-4 during its recent 2017-2018 outburst, observed simultaneously by the Swift and NuSTAR observatories. Altho…
Conflicting disk inclination estimates for the black hole X-ray binary XTE J1550-564
Riley~M. ~T. ~Connors, Javier~A. ~Garcia, James~F. ~Steiner +7
XTE J1550-564 is a black hole X-ray binary for which the dynamical characteristics are well established, and the broadband spectral evolution of the source has been well studied. I…
