On the Spin of the Black Hole in IC 10 X-1
James F. Steiner, Dominic J. Walton, Javier A. Garcia +5
The compact X-ray source in the eclipsing X-ray binary IC 10 X-1 has reigned for years as ostensibly the most massive stellar-mass black hole, with a mass estimated to be about twi…
On Estimating the High-Energy Cutoff in the X-ray Spectra of Black Holes via Reflection Spectroscopy
Javier A. Garcia, Thomas Dauser, James F. Steiner +3
The fundamental parameters describing the coronal spectrum of an accreting black hole are the slope of the power-law continuum and the energy at which it rolls over.…
X-ray Reflection Spectroscopy of the Black Hole GX 339-4: Exploring the Hard State with Unprecedented Sensitivity
Javier A. Garcia, James F. Steiner, Jeffrey E. McClintock +3
We analyze {\it simultaneously} six composite {\it RXTE} spectra of GX 339--4 in the hard state comprising 77 million counts collected over 196 ks. The source spectra are ordered b…
NuSTAR and Suzaku X-ray Spectroscopy of NGC 4151: Evidence for Reflection from the Inner Accretion Disk
M. L. Keck, L. W. Brenneman, D. R. Ballantyne +19
We present X-ray timing and spectral analyses of simultaneous 150 ks Nuclear Spectroscopic Telescope Array (NuSTAR) and Suzaku X-ray observations of the Seyfert 1.5 galaxy NGC 4151…
