Structure of the X-ray Emission from the Jet of 3C 273
H. L. Marshall, D. E. Harris, J. P. Grimes +12
We present images from five observations of the quasar 3C 273 with the Chandra X-ray Observatory. The jet has at least four distinct features which are not resolved in previous obs…
Chandra Observations of the X-ray Narrow-Line Region in NGC 4151
P. M. Ogle, H. L. Marshall, J. C. Lee +1
We present the first high-resolution X-ray spectrum of the Seyfert 1.5 galaxy NGC 4151. Observations with the Chandra High Energy Transmission Grating Spectrometer reveal a spectru…
Chandra Observations of the Young Pulsar PSR B0540-69
P. Kaaret, H. L. Marshall, T. L. Aldcroft +6
The young pulsar PSR B0540-69 was one of the first targets observed with the Chandra X-Ray Observatory. The high angular resolution of Chandra allows us to resolve the compact nebu…
High Resolution X-Ray Spectra of Capella: Initial Results from the Chandra High Energy Transmission Grating Spectrometer
C. R. Canizares, D. P. Huenemoerder, D. S. Davis +10
High resolution spectra of the active binary Capella (G8 III + G1 III) covering the energy range 0.4-8.0 keV (1.5-30 Angstroms) show a large number of emission lines, demonstrating…
Chandra Discovery of a 100 kpc X-ray Jet in PKS 0637--752
D. A. Schwartz, H. L. Marshall, J. E. J. Lovell +18
The quasar PKS 0637-753, the first celestial X-ray target of the Chandra X-ray Observatory, has revealed asymmetric X-ray structure extending from 3 to 12 arcsec west of the quasar…
Early Results from the Chandra X-ray Observatory
H. L. Marshall
We present some early results on AGN from the Chandra X-ray Observatory, highlighting high resolution spectroscopy using the High Energy Transmission Grating Spectrometer (HETGS).…
