Accretion Disk Wind of Hercules X-1 during the Short High State
(2023-12-05)
Hercules X-1 is a nearly edge-on X-ray binary with a warped, precessing accretion disk, which manifests through a 35-day cycle of alternating High and Low flux states. This disk precession introduces a changing line of ...
High-density Reflection Spectroscopy of Black Hole X-Ray Binaries in the Hard State
(2023-07-12)
We present a high-density relativistic reflection analysis of 21 spectra of six black hole X-ray binaries in the hard state with data from NuSTAR and Swift. We find that 76% of the observations in our sample require a disk ...
Disks and Jets : Gravity, Rotation and Magnetic Fields
(2015-10)
Magnetic fields are fundamental to the dynamics of both accretion disks and the jets that they often drive. We review the basic physics of these phenomena, the past and current efforts to model them numerically with an ...
