The X-Ray Observatory Suzaku
High-sensitivity wide-band X-ray spectroscopy is the key feature of the Suzaku X-ray observatory, launched on 2005 July 10. This paper summarizes the spacecraft, in-orbit performance, operations, and
Evidence for shock acceleration of high-energy electrons in the supernova remnant SN1006
HIGH-ENERGY cosmic rays (relativistic heavy nuclei) play an important role in heating interstellar matter in the Milky Way1,2, and they affect chemical abundances through collisions with atoms in the
Systematic Spatial Variations of the Spectrum of Synchrotron X-rays from the Youngest Galactic Supernova Remnant G1.9+0.3
Our 50 ks Chandra observation of the small radio supernova remnant (SNR) G1.9+0.3 shows a complete shell structure with strong bilateral symmetry, about 100'' in diameter. The radio morphology is
A Chandra X-Ray Survey of Ejecta in the Cassiopeia A Supernova Remnant
We present a survey of the X-ray-emitting ejecta in the Cassiopeia A supernova remnant (SNR) based on an extensive analysis of over 6000 spectral regions extracted on 25-10'' angular scales using the
Constraints on the physics of type ia supernovae from the x-ray spectrum of the tycho supernova remnant
We explore the relationship between the models for progenitor systems of Type Ia supernovae and the properties of the supernova remnants that evolve after the explosion. Most models for Type Ia
ASCA observations of the Large Magellanic Cloud supernova remnant sample: Typing supernovae from their remnants
We present our first results from a study of the supernova remnants (SNRs) in the Large Magellanic Cloud (LMC) using data from ASCA. The three remnants we have analyzed to date, 0509-67.5, 0519-69.0,
RADIOACTIVE SCANDIUM IN THE YOUNGEST GALACTIC SUPERNOVA REMNANT G1.9+0.3
We report the discovery of thermal X-ray emission from the youngest Galactic supernova remnant G1.9+0.3, from a 237 ks Chandra observation. We detect strong K? lines of Si, S, Ar, Ca, and Fe. In
The radio expansion and brightening of the very young supernova remnant G1.9 + 0.3
Recent radio observations of the small Galactic supernova remnant G1.9 + 0.3 made at 4.86 GHz with the Very Large Array are presented, and compared with earlier observations at 1.49 GHz which have a
EXPANSION VELOCITY OF EJECTA IN TYCHO's SUPERNOVA REMNANT MEASURED BY DOPPLER BROADENED X-RAY LINE EMISSION
We show that the expansion of ejecta in Tycho's supernova remnant (SNR) is consistent with a spherically symmetric shell, based on Suzaku measurements of the Doppler broadened X-ray emission lines.
The 'Quiescent' black hole in M87
It is believed that most giant elliptical galaxies possess nuclear black holes with masses in excess of 10 8 M⊙. Bondi accretion from the interstellar medium might then be expected to produce
