Collisional Plasma Models with APEC/APED: Emission-Line Diagnostics of Hydrogen-like and Helium-like Ions
- R. Smith, N. Brickhouse, D. Liedahl, J. Raymond
- Physics
- 26 June 2001
New X-ray observatories (Chandra and XMM-Newton) are providing a wealth of high-resolution X-ray spectra in which hydrogen- and helium-like ions are usually strong features. We present results from a… Expand
Detection of an unidentified emission line in the stacked X-ray spectrum of galaxy clusters
- E. Bulbul, M. Markevitch, A. Foster, R. Smith, M. Loewenstein, S. Randall
- Physics
- 10 February 2014
We detect a weak unidentified emission line at E = (3.55-3.57) ± 0.03 keV in a stacked XMM-Newton spectrum of 73 galaxy clusters spanning a redshift range 0.01-0.35. When the full sample is divided… Expand
Ionization Equilibrium Timescales in Collisional Plasmas
Astrophysical shocks or bursts from a photoionizing source can disturb the typical collisional plasma found in galactic interstellar media or the intergalactic medium. The spectrum emitted by this… Expand
Soft X-Ray Scattering and Halos from Dust
Small-angle scatterings of X-rays by interstellar dust particles create halos around X-ray sources. The halo intensity and its projected radial distribution around a source can provide important… Expand
Suzaku Observations of the Local and Distant Hot ISM
- R. Smith, M. Bautz, +18 authors N. Yamasaki
- Physics
- 29 September 2006
Suzaku observed the molecular cloud MBM 12 and a blank field less than 3 ◦ away to separate the local and distant components of the diffuse soft X-ray background. Towards MBM 12, a local (D 275pc) O… Expand
A Million Second Chandra View of Cassiopeia A
- U. Hwang, J. Laming, +20 authors Jessica S. Warren
- Physics
- 30 September 2004
We introduce a million second observation of the supernova remnant Cassiopeia A with the Chandra X-Ray Observatory. The bipolar structure of the Si-rich ejecta (northeast jet and southwest… Expand
Discriminating the Progenitor Type of Supernova Remnants with Iron K-Shell Emission
- H. Yamaguchi, C. Badenes, +11 authors H. Uchida
- Physics
- 20 March 2014
Supernova remnants (SNRs) retain crucial information about both their parent explosion and circumstellar material left behind by their progenitor. However, the complexity of the interaction between… Expand
XMM-Newton Observations of the Galactic Supernova Remnant CTB 109 (G109.1–1.0)
We present the analysis of the X-ray Multimirror Mission (XMM-Newton) European Photon Imaging Camera (EPIC) data of the Galactic supernova remnant (SNR) CTB 109 (G109.1-1.0). CTB 109 is associated… Expand
An X-Ray Jet Discovered by Chandra in the z = 4.3 Radio-selected Quasar GB 1508+5714
- Aneta Siemiginowska, R. Smith, +4 authors C. University
- Physics
- 9 October 2003
We report the Chandra discovery of an X-ray jet associated with the z = 4.3 radio-loud quasar GB 1508+5714. The jet X-ray emission peaks ~2'' to the southwest of the quasar core. We present archival… Expand
Chandra View of Kesteven 79: A Nearly Isothermal Supernova Remnant with Rich Spatial Structure
A 30 ks Chandra ACIS-I observation of Kes 79 reveals rich spatial structures, including many filaments, three partial shells, a loop, and a "protrusion." Most of them have corresponding radio… Expand
