Chandra--ASCA--RXTE observations of the micro-quasar GRS 1915+105
J. C. Lee, N. S. Schulz, C. S. Reynolds +2
A Chandra AO1 30ks HETGS observation of the X-ray transient micro-quasar GRS 1915+105 reveals absorption edges and faint line emission over the HETG energy range. We find from a pr…
X-ray iron line variability: constraints on the inner accretion disk
C. S. Reynolds
After reviewing the basic physics of X-ray reflection in AGN, we present three case studies which illustrate the current state of X-ray reflection studies. For the low-luminosity A…
Compton reflection and iron fluorescence in AGN and GBHCs
C. S. Reynolds
Any cold, optically-thick matter in the vicinity of an accreting black hole, such as the accretion disk, can intercept and reprocess some fraction of the hard X-ray continuum emiss…
The changing X-ray period of the Seyfert galaxy IRAS18325-5926
A. C. Fabian, J. C. Lee, W. N. Brandt +3
We report on two observations of the Seyfert galaxy IRAS18325-5926 made in 1997 December and 1998 February with the Rossi X-ray Timing Explorer (RXTE). We find evidence for periodi…
