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…
Superluminal Radio Features in the M87 Jet and the Site of Flaring TeV Gamma-Ray Emission
- C. Cheung, D. Harris, Ł. Stawarz
- Physics
- 16 May 2007
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…
An X-Ray Study of Magnetic Field Strengths and Particle Content in the Lobes of FR II Radio Sources
- J. Croston, M. Hardcastle, D. Harris, E. Belsole, M. Birkinshaw, D. Worrall
- Physics
- 9 March 2005
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.…
FERMI LARGE AREA TELESCOPE GAMMA-RAY DETECTION OF THE RADIO GALAXY M87
- A. Abdo, M. Ackermann, Ł. Stawarz
- Physics
- 19 October 2009
We report the Fermi Large Area Telescope (LAT) discovery of high-energy (MeV/GeV) γ-ray emission positionally consistent with the center of the radio galaxy M87, at a source significance of over 10σ…
X-Ray Emission Processes in Radio Jets
- D. Harris, H. Krawczynski
- Physics
- 27 September 2001
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…

X-Ray Emission from Extragalactic Jets
- D. Harris, H. Krawczynski
- Physics
- 11 July 2006
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…
The Chandra X-Ray Observatory Resolves the X-Ray Morphology and Spectra of a Jet in PKS 0637–752
- G. Chartas, D. Worrall, B. Wilkes
- Physics
- 10 May 2000
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…
A High-Resolution X-Ray Image of the Jet in M87
- H. Marshall, B. P. Miller, D. Harris
- Physics
- 10 September 2001
We present the first high-resolution X-ray image of the jet in M87 using the Chandra X-Ray Observatory. There is clear structure in the jet and almost all of the optically bright knots are detected…
The Outburst of HST-1 in the M87 Jet
The X-ray intensity of knot HST-1, 0.″85 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…
