Normalizing a Relativistic Model of X-ray Reflection: The Definition of the Reflection Fraction and its Implementation in relxill
T. Dauser, J. Garcia, D. J. Walton +4
The only relativistic reflection model that implements a parameter relating the intensity incident on an accretion disk to the observed intensity is relxill. The parameter used in…
The Origin of Black Hole Spin in Galactic Low-Mass X-ray Binaries
Tassos Fragos, Jeffrey E. McClintock
Galactic field black hole (BH) low-mass X-ray binaries (LMXBs) are believed to form in situ via the evolution of isolated binaries. In the standard formation channel, these systems…
Improved Reflection Models of Black-Hole Accretion Disks: Treating the Angular Distribution of X-rays
J. Garcia, T. Dauser, A. Lohfink +8
X-ray reflection models are used to constrain the properties of the accretion disk, such as the degree of ionization of the gas and the elemental abundances. In combination with ge…
The not-so-massive black hole in the microquasar GRS1915+105
D. Steeghs, J. E. McClintock, S. G. Parsons +3
We present a new dynamical study of the black hole X-ray transient GRS1915+105 making use of near-infrared spectroscopy obtained with X-shooter at the VLT. We detect a large number…
Understanding Compact Object Formation and Natal Kicks. IV. The case of IC 10 X-1
Tsing-Wai Wong, Francesca Valsecchi, Asna Ansari +4
The extragalactic X-ray binary IC 10 X-1 has attracted attention as it is possibly the host of the most massive stellar-mass black-hole (BH) known to date. Here we consider all ava…
X-ray reflected spectra from accretion disk models. III. A complete grid of ionized reflection calculations
J. Garcia, T. Dauser, C. S. Reynolds +4
We present a new and complete library of synthetic spectra for modeling the component of emission that is reflected from an illuminated accretion disk. The spectra were computed us…
Black Hole Spin via Continuum Fitting and the Role of Spin in Powering Transient Jets
Jeffrey E. McClintock, Ramesh Narayan, James F. Steiner
The spins of ten stellar black holes have been measured using the continuum-fitting method. These black holes are located in two distinct classes of X-ray binary systems, one that…
Understanding Compact Object Formation and Natal Kicks. III. The case of Cygnus X-1
Tsing-Wai Wong, Francesca Valsecchi, Tassos Fragos +1
In recent years, accurate observational constraints become available for an increasing number of Galactic X-ray binaries. Together with proper motion measurements, we could reconst…
Simulations of Magnetized Disks Around Black Holes: Effects of Black Hole Spin, Disk Thickness, and Magnetic Field Geometry
Robert F. Penna, Jonathan C. McKinney, Ramesh Narayan +3
The standard general relativistic model of a razor-thin accretion disk around a black hole, developed by Novikov & Thorne (NT) in 1973, assumes the shear stress vanishes at the rad…
