High resolution Chandra HETG and RXTE observations of GRS 1915+105 : A hot disk atmosphere & cold gas enriched in Iron and Silicon
Julia C. Lee,Christopher S. Reynolds,Norbert S. Schulz,Ron Remillard,Eric G. Blackman,A. C. Fabian +5 more
TL;DR: The time-averaged 30 ks Chandra HETGS observation of the micro-quasar GRS 1915+105 in the low hard state reveals for the first time in this source neutral K absorption edges from Fe, Si, Mg, & S ionized resonance absorption from H-, and He-like Fe (XXV, XXVI), Ca XX and possibly emission from neutral Fe Kalpha and ionized Fe XXV (forbidden, or the resonance emission component of a P-Cygni profile) are also seen as mentioned in this paper.

TL;DR: Athena+ X-IFU of young supernova remnants is used in this article to characterize individual parcels of ejected material in the line of sight in terms of kinematics, ionization and composition, providing access to the three dimensional geometry of the explosion.
Journal ArticleDOI
A Detection of an X-ray Wind and an Ionized Disk in the Chandra HETGS Observation of the Seyfert 2 Galaxy IRAS 18325-5926
TL;DR: In this article, Chandra high energy transmission Grating Spectrometer observations of the Seyfert 2 AGN IRAS 18325-5926 were used to detect a photoionized wind originating in the obscuring torus/global covering around the black hole or outer edge of the accretion disk.
Journal ArticleDOI
The Hard X-Ray View of Reflection, Absorption, and the Disk-Jet Connection in the Radio-Loud AGN 3C 33
Daniel A. Evans,Daniel A. Evans,James Reeves,Martin J. Hardcastle,Ralph P. Kraft,Julia C. Lee,Shanil N. Virani +6 more
TL;DR: In this article, the authors present results from Suzaku and Swift observations of the nearby radio galaxy 3C 33, and investigate the nature of absorption, reflection, and jet production in this source.
Journal ArticleDOI
A Search for H I Lyman $\alpha$ Counterparts to Ultra-Fast X-ray Outflows
TL;DR: In this paper, the authors search archival UV spectra at the expected locations of H I Ly$\alpha$ absorption for a large sample of ultra-fast outflows identified in XMM-Newton and Suzaku observations.
