Probing Relativistic Astrophysics Around SMBHs: The Suzaku AGN Spin Survey
C. S. Reynolds, L. W. Brenneman, A. M. Lohfink +5
In addition to providing vital clues as to the formation and evolution of black holes, the spin of black holes may be an important energy source in the Universe. Over the past coup…
X-ray spectral variability in NGC 3783
R. C. Reis, A. C. Fabian, C. S. Reynolds +6
NGC 3783 was observed for approximately 210ks by Suzaku and in this time showed significant spectral and flux variability at both short (20ks) and long (100ks) time scales. The ful…
Suzaku Observations of 4U 1957+11: Potentially the Most Rapidly Spinning Black Hole in (the Halo of) the Galaxy
Michael A. Nowak, Joern Wilms, Katja Pottschmidt +3
We present three Suzaku observations of the black hole candidate 4U 1957+11 (V1408 Aql) --- a source that exhibits some of the simplest and cleanest examples of soft, disk-dominate…
The Microquasar Cyg X-1: A Short Review
Michael A. Nowak, Joern Wilms, Katja Pottschmidt +1
We review the spectral properties of the black hole candidate Cygnus X-1. Specifically, we discuss two recent sets of multi-satellite observations. One comprises a 0.5-500 keV spec…
Using the X-ray Dust Scattering Halo of Cygnus X-1 to determine distance and dust distributions
Jingen Xiang, Julia C. Lee, Michael A. Nowak +1
We present a detailed study of the X-ray dust scattering halo of the black hole candidate \cygx1 based on two \chandra\ HETGS observations. Using 18 different dust models, includin…
The Spin of the Supermassive Black Hole in NGC 3783
L. W. Brenneman, C. S. Reynolds, M. A. Nowak +9
The Suzaku AGN Spin Survey is designed to determine the supermassive black hole spin in six nearby active galactic nuclei (AGN) via deep Suzaku stares, thereby giving us our first…
