CIAO: Chandra's data analysis system
The CIAO (Chandra Interactive Analysis of Observations) software package was first released in 1999 following the launch of the Chandra X-ray Observatory and is used by astronomers across the world
We report the Fermi-LAT discovery of high-energy (MeV/GeV) gamma-ray emission positionally consistent with the center of the radio galaxy M87, at a source significance of over 10 sigma in ten-months
An X-Ray Study of Magnetic Field Strengths and Particle Content in the Lobes of FR II Radio Sources
We present a Chandra and XMM-Newton study of X-ray emission from the lobes of 33 classical double radio galaxies and quasars. We report new detections of lobe-related X-ray emission in 11 sources.
Superluminal Radio Features in the M87 Jet and the Site of Flaring TeV Gamma-Ray Emission
Superluminal motion is a common feature of radio jets in powerful γ-ray-emitting active galactic nuclei. Conventionally, the variable emission is assumed to originate near the central supermassive
X-Ray Emission from Extragalactic Jets
AbstractThis review focuses on the X-ray emission processes of extragalactic jets on scales resolvable by the subarcsec resolution of the Chandra X-ray Observatory. It is divided into four parts. The
X-ray Emission Processes in Radio Jets
The emission processes responsible for the observed X-rays from radio jets are commonly believed to be nonthermal, but in any particular case, it is unclear if synchrotron emission or one or more
The Chandra X-ray observatory resolves the X-ray morphology and spectra of a jet in PKS 0637-752
The core-dominated radio-loud quasar PKS 0637-752 (z = 0.654) was the first celestial object observed with the Chandra X-Ray Observatory, offering the early surprise of the detection of a remarkable
The Outburst of HST-1 in the M87 Jet
The X-ray intensity of knot HST-1, 085 from the nucleus of the radio galaxy M87, has increased by more than a factor of 50 during the last 5 yr. The optical increase is similar, and our more limited
The X-Ray-Radio Alignment in the z = 2.2 Radio Galaxy PKS 1138–262
We present high-resolution X-ray observations of the narrow-line radio galaxy PKS 1138-262 at z = 2.156 with the ACIS-S detector on the Chandra X-Ray Observatory. These observations show that the
