FUSE Observation of the Non-Radiative Collisionless Shock in the Remnant of SN1006
K. E. Korreck, J. C. Raymond, T. H. Zurbuchen +1
The appearance of the young supernova remnant SN1006 is dominated by emission from non-radiative shocks in the NE and NW regions. At X-ray energies the northeast shock exhibits pre…
Simultaneous Chandra and RXTE Spectroscopy of the Microquasar H~1743-322: Clues to Disk Wind and Jet Formation from a Variable Ionized Outflow
J. M. Miller, J. Raymond, J. Homan +7
We observed the bright phase of the 2003 outburst of the Galactic black hole candidate H 1743-322 in X-rays simultaneously with Chandra and RXTE on four occasions. The Chandra/HETG…
Molecular Cloud Formation Behind Shock Waves
Edwin A. Bergin, Lee W. Hartmann, John C. Raymond +1
We examine the formation of molecular gas behind shocks in atomic gas using a chemical/dynamical model, particular emphasis is given to constraints the chemistry places on the dyna…
Chandra Observation of V426 Oph: Weighing the Evidence for a Magnetic White Dwarf
Lee Homer, Paula Szkody, John C. Raymond +6
We report the results of a 45 ks Chandra observation of the cataclysmic variable V426 Ophiuchus. The high resolution spectrum from the high-energy transmission grating spectrometer…
Atomic X-Ray Spectra of Accretion Disk Atmospheres in the Kerr Metric
Mario A. Jimenez-Garate, Duane A. Liedahl, Christopher W. Mauche +1
We calculate the atmospheric structure of an accretion disk around a Kerr black hole and obtain its X-ray spectrum, which exhibits prominent atomic transitions under certain circum…
Reprocessing of Soft X-ray Emission Lines in Black Hole Accretion Disks
Christopher W. Mauche, Duane A. Liedahl, Benjamin F. Mathiesen +2
By means of a Monte Carlo code that accounts for Compton scattering and photoabsorption followed by recombination, we have investigated the radiation transfer of Ly alpha, He alpha…
